PRE-DELIVERY SERVICE OF MOWER BY DEALER
Before proceeding with the Pre-Delivery Service of your mower,
please read the safety instructions manual in its entirety. Only
your authorized Wright dealer should perform the Pre-Delivery
Service of the mower.
WARNING
The Wright Mower is shipped completely assembled and has been adjusted and tested at the factory.
However, due to the jostling of the shipping process and the delivery time lapse, the following items need to
be repeated again before starting the mower. After you have uncrated the mower, follow these procedures in
the order indicated:
Inspect the mower for any damage, unusual conditions or missing parts.
Inspect the mower for all of its decals, especially the warning decals. There should be one blade warning
decal on each side of the deck, the “shield missing” decal under the blade belt cover, and the dash decal.
Check (and fill if necessary) engine oil level according to the engine manufacturer’s recommendation.
Check (and fill if necessary) hydraulic fluid level. Use fully SYNTHETIC oil: Mobil-1 15W-50 (see Hydro
Check/Fill section of this manual).
Check rear tire pressure – 18 – 22 psi. is recommended. Use the higher pressures for heavier operators.
Front Casters are equipped with non-pneumatic tires and do not require any air. Lowering tire pressure will
affect deck pitch. Always check pitch any time tire pressure is set below recommended pressures.
Lubricate all appropriate moving parts (see the Lubrication section of this manual).
Check the battery to see that the cables are tight and connected properly. The battery is 12 volts and is a
maintenance-free battery. Only charge the battery if it will not start the mower properly.
Add regular unleaded gasoline to fuel tank. (use a minimum of 87 octane gasoline) (You may use gasoline
containing up to 10% ethanol and gasoline containing up to 5% of methanol.)
Check brake safety interlock.
Try starting the engine with the parking brake released. (Engine should not start. If engine starts,
service the parking brake locking system)
Apply parking brake
Start the engine according to the engine manufacturer’s recommendation. Let the engine run at low - mid
RPM for several minutes to ensure the engine oil reaches all of the engine parts and gets the hydraulic fluid
circulating through the pumps, etc.
Check if the parking brake locking system prevents the units from being driven while engaged. If not,
service the parking brake locking system.
Release the parking brake. Next, move the hand control levers, one at a time, to make the wheels move in
forward and backward rotation.
Before testing the blade clutch/brake operation, make sure the area is clear and there is nothing vulnerable
to possible thrown objects from under the mower. No one should be near the mower deck or in its line of
discharge at this or at any time. The discharge chute deflector should be in the down position.
Move the engine throttle control to ¾ RPM speed setting.

Turn on the blade clutch switch. Run blades for approximately one minute. Next, engage and disengage
the blades a few times about 10 seconds apart. If the blades do not start and stop in a few seconds each
time, service the blade brake system.
With the blades on, disengage the OPC switch to test the Operator Presence Control switch (OPC). A time
delay has been added to the OPC system. The engine should die and the blades should stop with-in 6-9
seconds after stepping off of the foot platform. If not, service the OPC system.
Disengage the blades.
Drive the mower around on a level parking lot. Check that the mower drives in a straight line when both
hand controls are at the full speed position. (If not, refer to How to Perform The Tracking Adjustment section
of this manual) (The control handles may not line up perfectly)
As you drive the mower, listen for any unusual noises and test for irregular operation and adjust or
service as necessary.
Go over the safety information and operating procedures in this manual with the customer. Instruct each
customer in proper operation and observe the customer during their initial operation on a level parking lot.
Repeat until the customer is familiar and comfortable with the basic operation and use of the mower.
• Dealer:

WARNING
1.6 User Clothing
DO NOT operate the mower while wearing sandals, tennis shoes, sneakers, or shorts. Always wear long
non-baggy pants. Wear high-top leather steel-toed work boots with thick, textured tread, soft-rubber
soled at all times. Hard or smooth soled shoes are too slippery for a good footing on mower platform.
NEVER wear loose-fitting clothing or jacket pockets that can get caught on the handlebars or control
levers of any mower you drive. Wearing safety glasses, ear protection and safety shoes is advisable and
required by some local ordinances and insurance regulations.
1.7 Inspect Mower Before Each Use
DO NOT use the mower if any parts are not maintained in good operating condition. Examine the moving
parts prior to each use. Look for excessive wear, bald or worn tires, cracks in parts, loose or missing bolts,
cotter pins, linchpins and replace before operating the mower. Make sure all safety equipment provided with
the mower is in good operating order, including all the warning decals and the required operator-presence
device which stops the engine and blades when the foot-operated Operator Presence Control (OPC) switch
is released. (To test the OPC, follow instructions in the Operating Instructions section of this manual.)
Inspect the two anti-tip rollers and their respective bolts at the rear of the mower for tightness and proper

operation. Be sure that all parts of the hand-operated hydraulic control system are tight and secure. This is
to reduce the possibility that the mower could have a loss of control during operation and compromise
operator safety. Ensure deck pitch is between 1/4 - 3/8”. (Refer to the maintenance interval chart at the end
of this manual)
WARNING
1.8 Regular Mower Safety Maintenance
Keep your Wright mower in good operating condition, and keep safety devices and shields in place and in
working condition. Replace worn tire(s) with less than 3/32” of any tread groove left. Use tires with the tread
pattern specified by Wright Mfg., Inc. only. DO NOT change the engine governor settings or over-rev the
engine contrary to engine manufacturer specifications. Failure to comply can compromise operator safety,
shorten equipment life and void your manufacturer’s warranty. Keep all nuts, bolts, and screws tight to be
sure the equipment is in safe working condition. Check the blade mounting bolts for proper tightness every
eight (8) hours of operation. Check the blades for excessive wear and sharpness every four to eight (4-8)
hours of operation. Sharpen dull blades. Replace blades when they become excessively worn. The mower
should not be used after the blades or other part of the mower strikes a foreign object, until conducting a
thorough inspection and any damage is repaired. When inspecting or changing blades, turn off the blade
clutch switch, apply the parking brake, stop the engine and remove the key. Make sure the chute deflector is
always in place and operating properly. Replace if the deflector becomes worn or ceases to properly deflect
the grass in a safe manner. (Refer to the maintenance interval chart at the end of this manual)
WARNING
1.9 Work Area Conditions & Inspection
Prior to operating the unit, carefully inspect all lawn/ground areas where you plan to use the mower for
hidden, hard-to-see objects or uneven ground that may be hidden in the grass. Clear the work area of
moveable objects such as wires, rocks, glass, toys, etc. that might be picked up by the mower and
dangerously thrown. Remove, if possible, or mark the location of all immovable objects or irregular areas
and be sure not to hit them with any part of the mower, its deck or the blades. Obstacles such as holes,
abrupt changes in ground contour, tree trunks, stumps or roots, pipes protruding from the ground, paving
edges, etc. in the path of operation can abruptly turn or stop the mower. This could throw you off the mower
or into and possibly over the handle bars causing serious injury or death. The faster you are moving the
more potential there is for injury. Mow only in daylight or in good artificial light. Keep away from drop-offs,
the edges of ponds, streams, pools, etc. especially at the bottom of slopes. Do not mow when children or
others are around. When the Wright mower is in use, never direct the grass discharge toward bystanders,
traffic, cars or buildings nor allow anyone within 50 feet of the machine while in operation. Thrown objects
can pass through glass windows and some walls of buildings. There is extreme risk of danger from thrown
objects or being cut by the blades of the mower or being run over if you lose control. Never operate the
mower in an enclosed area without good, approved ventilation. Exhaust fumes are dangerous.
WARNING
1.10 Initial Operating Safety Guidelines
• Read and understand the warnings on the instrument panel of the mower.
• Keep a firm hold on the stationary handle at all times.
• Keep both feet on the foot platform at all times.
• Know the controls and how to stop quickly.
• Before attempting to start the engine, follow all starting instructions below and in the engine operator’s
manual.
• Look behind before backing up.
7

• Before leaving the operator’s position, even momentarily, turn off the blade clutch engagement switch and
apply the parking brake. Keep others from coming near the mower. Get back on the mower as soon as
possible.
• When leaving the Wright mower unattended, turn off the blade clutch engagement switch, apply the
parking brake, stop the engine and remove the key. Never leave the machine unattended on a slope in
case someone disengages the parking brake. This could create a rollover hazard.
• When transporting, driving onto transport vehicles, into buildings, across parking lots or otherwise not
mowing grass, turn off the blade clutch engagement switch to reduce risk of thrown objects and rotating
blade hazard. After coming to a stop apply the parking brake, stop the engine and remove the key.
• Before performing any maintenance or repair service, disengage power to blades, apply the parking brake,
stop the engine, remove ignition key and spark plug wire from spark plug(s).
• All operators of this mower should exercise caution when driving this mower at high speeds. Sudden
acceleration or deceleration may cause serious injury.
• Do not allow inexperienced persons to operate the mower until they have read and understood these
safety instructions. Operate the mower at slower speeds while becoming familiar with it.
• The grass discharge chute deflector must be installed at all times and in the down position except that it
may be raised when cleaning out the deck or a grass catcher is installed or a mulch kit and block-off plate
is properly installed.
• If the mower discharges grass clogs, turn off the blade clutch switch, apply the parking brake, stop the
engine and remove the key before removing obstruction(s).
• Keep all shields and covers in place, namely, all blade and belt covers, engine shields, and grass
discharge chute deflector.
• Keep hands, feet and clothing away from rotating parts, especially the rear wheels, blades, engine
flywheel, belts and pulleys.
• Do not touch engine, muffler or hydraulic system while engine is running or soon after it is stopped. These
areas can be so hot as to cause severe burns.
• Clean grass, leaves and lubricant spills from surfaces after use to prevent fire hazard.
• Be alert for traffic when crossing roads or operating near roadways.
• Before climbing curbs, crossing gravel drives, sidewalks or roads, turn off the blades and wait for them to
stop.
WARNING
1.11 Safety for Maintenance
• Repairs carried out by untrained or unauthorized personnel may result in personal injury or serious
malfunction of the Stander.
• If Guarding is removed for inspection and component replacement, ensure the parking brake is applied
and key is removed prior to inspecting or making repairs and that the guarding is replaced before
operation.
1.12 Operation In Forward Direction
Always keep a firm grip on the mower stationary handlebar with both hands. Operate the mower slowly until
you become familiar with how the mower operates. Do not operate the mower faster than conditions allow.
For example, hills, wet or bumpy ground, dim light or high grass are all conditions requiring slower speeds.
Never operate the mower at the highest speed unless you are on level, wide, open areas of clearly visible
ground or transporting on paved areas. Speeding with any mower is dangerous, and so is traveling faster
than conditions should permit on this mower. Sudden stops from excessive speed or falling off the mower
may cause serious injury or death.
1.13 Operation In Reverse
Always keep a firm grip on the mower stationary handlebar with both hands. Keep both feet firmly on the
foot platform. Look behind you before backing to prevent injuring yourself or anyone behind you. Operate
8

the mower very slowly, inching it backward until you become familiar with how the mower operates. Always
operate slowly if in an awkward location or position. While backing up never place your foot or feet on the
ground near the back edge of the mower to prevent serious personal injury if the mower were to run over
you.
1.14 Zero-Radius Turn Operation
During zero-radius turns (when one mower wheel rotates backwards while the other rotates forward) drive
extra slowly to reduce the possibility of losing traction, or control, or becoming dizzy. This will help prevent
you from being thrown off the mower. Be aware that if you do a turn on a slope you may go through all of the
orientations to a slope mentioned below and must handle the mower accordingly.
1.15 Operation on Slopes
DO NOT operate on steep slopes 25 degrees or greater for long periods or engine damage may occur. Do
not operate the mower on slopes steeper than you can feel secure about the traction of the tires and the
stability of the mower. Do not operate the mower on slopes at all when the grass is wet. There is a danger
of suddenly sliding sideways or down the hill. When operating on a slope, travel across the grade whenever
possible, not in an up or down pattern. Reduce speed and exercise extreme caution on slopes and in sharp
turns to prevent tipping or loss of control. Be especially cautious when changing direction on slopes.
When pointing up a slope, your mower has the most weight on the drive wheels and therefore the most
traction at the tires. However, this is the angle that it has the most tendency to tip back (“pop a wheelie.”)
This is the preferred angle for mowing small areas of steeper slopes.
Recommendations for this angle:
• Lean as far forward as possible to add your weight to the front of the mower.
• Accelerate gently. Do not accelerate quickly to avoid “popping a wheelie”.
• If backing down the hill, do not stop suddenly but slow down gradually.
When pointing down a slope, your mower has the least weight on the rear drive wheels and therefore the
least traction at the tires. This is the angle that the mower has the most tendency to slide. However, this is
the angle that it has the least tendency to tip back. Avoid this angle, as it has the least advantage for your
mower.
Recommendations for this angle:
• Lean back with arms stretched out straight while holding onto the stationary handlebar. This transfers
more of your body weight to the rear drive wheels for more traction.
• Do not change speed suddenly to minimize the tendency of going into a slide. Accelerate and decelerate
gently. If you ever go into an uncontrolled slide while pointing down a slope the recommended procedure
is to let go of the handles and jump off if necessary. Otherwise, control the mower gently and stay off
slopes that tend to make the wheels slide.
When crossing a slope sideways, your mower has the average amount of weight on the drive wheels
versus the front wheels, similar to level ground. However, this angle leaves the least weight on the higher
side drive wheel, tending to make it slip. This is the preferred angle for mowing large areas of gentle
slopes.
Recommendations for this angle:
Lean back. This adds weight to the rear drive wheels and will allow you to mow more quickly across the
slope without sliding. These are general guidelines only. The mower function and comfort will vary
depending on mowing environment, operator driving style and preference.
• To reduce the chances of “popping-a-wheelie”, do not accelerate quickly.

Note: Excessively worn tire tread is dangerous. Replace tire(s) with less than 3/32” of any tread groove left.
Use tires with the tread pattern recommended by Wright Mfg., Inc. only. Keep the tire pressure in the drive
tires between 18 and 22 psi. Higher pressures will cause the tires to have less traction which may prevent
safe operation. Lower pressure will affect the deck pitch, thus creating a level deck or a reverse pitched deck
and this WILL compromise cut quality. (Refer to tire maintenance and pressure section)
1.16 Fuel Safety
Handle gasoline with care – it is highly flammable. Do not smoke while
handling gasoline. Use an approved gasoline container. Never remove the
fuel cap or add gasoline to a running or hot engine or an engine that has not
been allowed to cool for several minutes after running. Never fill the tank
indoors and always clean up spilled gas. NEVER store the equipment with
gasoline in the tank inside a building where fumes may reach an open flame
or spark. Allow the engine to cool before storing in any enclosure.
1.17 Hydraulic Safety
Keep body and hands away from pin holes or fittings that eject hydraulic fluid under high pressure. Use
paper or cardboard and not hands to search for leaks. Hydraulic fluid escape under high pressure may have
sufficient force to penetrate skin and cause serious injury. If foreign fluid is injected into the skin, it must be
surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.
Seek medical attention immediately. Make sure all hydraulic fluid connections are tight and all hydraulic
hoses and lines are in good condition before starting your Wright mower. Hydraulic fluid is under high
pressure. If you need service on your hydraulic system, please see your authorized Wright dealer.
1.18 Using a Spark Arrester
The engine in this machine is not equipped with a spark arrester muffler. It is in violation of California Public
Resources Code Section 4442 to use or operate the engine on or near any forest-covered, brush-covered, or
grass covered land unless the exhaust system is equipped with a spark arrester meeting any applicable local
or state laws. Other states or federal area may have similar laws.
1.19 Replacement Parts
Use of parts other than specified parts supplied by Wright Manufacturing, Inc. may compromise the safe use
of the mower, are not recommended and their use could void the warranty. Always check with your Dealer
Wright is fully concerned with your safety. Please read the above repeatedly until you fully
understand the methods to promote the safest operation possible.
REMEMBER – YOUR MOWER CAN BE ONLY ASSAFE AS THE OPERATOR.
FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT IN
SERIOUS INJURY OR DEATH.

4 OPERATING INSTRUCTIONS
If you are not completely familiar with the Safety Instruction
Manual read it now before proceeding with the operation of the
mower. REMEMBER THERE ARE CERTAIN PRECAUTIONS
LISTED IN THIS MANUAL THAT YOU MUST NOW TAKE BEFORE
STARTING THE MOWER.
WARNING
4.1 Inspect Mower Before Each Use
Inspection of Mower: Do not use the mower if any parts are not maintained in good operating condition.
Examine all moving parts prior to each use. Look for excessive wear, bald drive tires or worn out front tires
(normally smooth), cracks in parts, loose or missing bolts, cotter, linchpin or “hair” pins or cable yoke pins
and replace before operating the mower. Make sure all safety equipment provided with the mower is in good
operating order, including all warning decals and the operator-presence device which stops the engine and
blades when the foot-operated Operator Presence Control (OPC) switch is released. To test the OPC, follow
the instructions given later in this manual. Inspect the two anti-tip rollers and their respective bolts at the rear
of the mower for tightness and proper operation. Ensure that all parts of the Quad-Lever™ control system
are tight and secure. This is to reduce the possibility that the mower could have a loss of control or safety.
Basic Operation: The following procedures are to guide you through the basic operation of the mower. You
should be a qualified mower operator according to the safety section of this manual. If this is your first time,
operation should only be done with the assistance of your dealer on a level area. You should go through
each step, in the order indicated, every time you start the mower.
4.2 How to start the mower
Before starting the engine
• Move mower to an open, well ventilated area.
• Make sure the control levers are in the exact neutral position.
• Apply the parking brake if it is not already set.
• Turn OFF the blade engaging switch if it is on.
• Check the engine oil.
• Turn fuel valve to the “ON” position.
Starting the engine
• Start the engine according to the engine manufacturer’s recommendation, see engine manual. Set the
throttle control lever near mid throttle, pull out on the choke control knob and
turn the key to the start position. Do not engage the starter for more than ten (10) seconds at a time. This
may overheat the starter and the wiring systems. Wait ten (10) seconds between attempts. If the engine
does not start after several attempts or stalls frequently, take the mower in for service.
After starting the engine according to the engine manufacturer’s recommendation, push in on the choke
control knob to open the choke valve, let the engine run for several minutes to get the hydraulic fluid
circulating through the pumps, etc. and to allow the engine to warm up. Do not over-rev a cold engine.
4.3 How to drive the mower
While standing, both feet should be firmly placed on the foot platform. Set the engine speed about a fourth of
the way from idle. Release the parking brake. Now try moving the hand control levers, one at a time, very
slightly, forward and backward. Check to see if the wheels move forward and backward according to the
position of the levers. If not, check to see that the pump release valves are closed. With both feet still firmly
placed on the foot platform, increase the engine speed to about half of the way from idle speed. Release the
16

parking brake. The higher engine speed will make the controls much more responsive and the mower much
quicker; Use caution if it is your first time. Now try moving the hand control levers, one at a time, very
slightly, forward and backward. Gradually increase your speed until you are well acquainted with the
operation of the hand controls and the mower’s behavior. After gaining a good feel for how the mower
handles, gradually attempt higher engine speeds until familiar with operation at full throttle engine speed.
Unusual noises or irregular operation:
As you drive the mower, listen for any unusual noises and test for irregular operation and adjust or service as
necessary.
4.4 How to Stop and Park the Mower
Come to a complete stop. If the blades are on, turn them off using the switch on the instrument panel. Make
sure the control levers are in the exact neutral position. Set the parking brake, reduce the engine speed to
idle, (keep engine running at the idle speed for about 1 minute) shut off the ignition switch to stop the engine
and then remove the key from the ignition switch. Turn fuel valve to the “OFF” position. The mower is now
parked. Do not leave mower unattended on a sloped surface.
WARNING
4.5 Driving the Mower Over a Curb
To climb a curb, first see the Safety Instructions section of this manual, especially the parts on:
• Initial Operating Safety Guidelines
• Operation In Reverse
• Operation In Forward Direction
Drive the mower in reverse at a 45 degree angle to the curb (with the left side of the mower closest to the
curb) until you are within an inch or two of the left-rear tire hitting the curb. Stop and then gradually bump
into the curb with that tire until it is just on top of the curb. If the tire slips even while lurching the mower into
the curb, then the curb is too high and you should use ramps or find another way. The mower should still be
at a 45 degree angle to the curb. Now, while maintaining the same angle to the curb, continue to back up
until the right-rear tire is close to the curb. Using the same technique lurch the right tire onto the curb. After
both wheels are on top of the curb, turn the mower counterclockwise and back up so the left caster wheel
comes over and last should be the right caster wheel as the mower is twisting to the left (counterclockwise).
The technique works the best if you try not to drive backwards at a near 90 degree angle to the curb but get
all of the wheels to go over while the mower is moving at least a 45 degree angle to the curb. To drive off a
curb, first try driving up onto it to make sure the curb is not too high. If the curb is not too high, drive the
right-front caster off first while driving toward the curb at a 45 degree angle (the curb should be to your right).
Then, maintain that 45 degree angle so the left caster goes over, then the right-rear wheel, then the left rear
wheel. WARNING: Do NOT step off the mower during ANY maneuver.
WARNING
4.5.1 Never drive straight onto or off a curb.
Never drive straight onto or off a curb. If you do the whole procedure at a very sharp angle it will tend to
minimize the contact of the mower deck with the curb and you will be able to more safely control the mower.
4.6 Mowing on Varying Terrain
See the Safety Instructions section of this manual, especially the parts on:
• Initial Operating Safety Guidelines
• Operation On Slopes
• Operation In Reverse
• Operation In Forward Direction
• Operation During Zero-Radius Turns

4.7 How to Adjust Neutral
Neutral refers to the mower movement when the engine is set to
full throttle, parking brake is off, and the control levers are in the
neutral position. The mower should not move forward or
backward during this time. If the mower is moving forward or
rearward, the neutral setting must be adjusted. The hydraulic
pump has a Return-to-Neutral (RTN) device built into the linkage
of the pump. Before adjusting neutral, it is necessary to lift the
rear drive wheels off the ground using a jack and stands. To make
the adjustment, loosen the ¼” Allen bolt (A) and rotate the RTN
device on the pump corresponding to the wheel that needs
adjustment. If the right wheel turns in the neutral position, then
the right pump RTN needs to be adjusted. The RTN mechanism
should be rotated until the neutral position is found and then
retighten the ¼” allen bolt. Use care not to over tighten the allen
bolt. Repeat the procedure on the other pump if necessary.
A
4.8 Changing the Speed/Sensitivity
Adjustment
The controls are initially set with the Speed/Sensitivity Adjustment
in the faster, more sensitive position. If an operator is not
completely familiar with the mower operation the operator may
desire to decrease the ground speed. The slower setting has a
corresponding decrease in the sensitivity of the controls. In other
words, a given amount of movement of the control levers will cause
about a 25-30% change in the ground speed making the controls
less sensitive. After stopping the engine, the adjustment is made
by removing rod ends from the current holes in the pump levers and
reinstalling them into the alternate holes. The holes farthest from
the operator position are for the faster, more sensitive setting and
the holes closest to the operators position are the slower, less
Slow Hole
sensitive setting. You must then perform the Tracking Adjustment described below.
WARNING
4.9 How to Perform the Tracking Adjustment
First ensure that the tire pressure is equal on both rear drive tires (18-22 psi). Drive the mower on a level
parking lot with the engine at full throttle. Check that the mower drives in a straight line when both hand
controls are held to the full speed position. If not, park the mower and stop the engine. The adjustment is
made by loosening the jam-nuts on the control rods (this may need to be done to one or both control rods)
and adjusting the control rods. Once the jam-nuts are loosened at the top and bottom of the control rod
proceed to turning the control rod clockwise or counter-clockwise. Shortening the control rod will increase
the speed of the forward movement of the mower on that side. Lengthening the control rod will slow the
forward movement of the mower on that side.
In the “faster” Speed/Sensitivity setting (this is the factory setting) neither rod should be lengthened so much
that at full speed it pulls the pump control lever (on the sides of the pumps) against the internal pump stop.
Therefore, to reach the maximum capable speed, the rods should be lengthened one turn at a time until you
can feel, in the hand control, that the internal pump stop has been contacted. Then shorten the rod one turn
(damage to the hydro pump will occur if the controls are adjusted in a way that put direct pressure on the
internal pump stop). You will feel the slight resistance. There is no need to start the engine while checking
this incrementally. Remember, this procedure does not apply if the Speed/ Sensitivity Adjustment is in the
slower setting.
18

If the rod is made shorter it will increase the forward speed capability for that side of the mower and if the rod
is made longer it will slow down that side of the mower. So, if the mower is tracking to the left, either the left
side needs to go faster (by shortening the left-side rod) or the right side needs to go slower (by lengthening
the right-side rod). If the mower is tracking to the right, either the right side needs to go faster (by shortening
the right-side rod) or the left side needs to go slower (by lengthening the left-side rod). It is important that
neither rod should be shortened too far, as mentioned above.
The only reference point to limit the adjustment from becoming extremely off is the relative position of the
pump stop and the handlebar in the faster Speed/Sensitivity setting. Therefore, if everything is way off either
because you are installing new parts (or other reasons) you should only use the faster Speed/ Sensitivity
setting to get the tracking accurate and then change to the slower speed range and adjust the tracking only
one or two turns on either side.
After getting the mower to track straight, check and/or readjust the neutral adjustment on the pump by using
a ¼” allen wrench at the Return-to-Neutral (RTN) mechanism, if necessary. It is normal to make these
adjustments from time to time.
WARNING
4.10 How to Test/Use the Blade Clutch/Brake Switch
Before testing the blade clutch/brake operation, make sure the area is clear and there is nothing vulnerable
to thrown objects from under the mower. No one should be near the mower deck or in its line of discharge.
The discharge chute deflector should be in the down position. Move the engine throttle to ¾ speed setting.
When mowing, the engine speed should always be at its highest setting. The engine governor will regulate
the engine according to the different mowing conditions at that setting. Place both feet firmly on the foot
platform and turn on the blade clutch switch. Run blades for a minute or so. Try engaging and disengaging
the blades a few times about 10 seconds apart. If the blades do not start and stop in 6-9 seconds each time,
service the blade brake system or contact your local Wright dealer. Under mowing load, the clutch’s life will
be the greatest if engaged and disengaged at the ¾ throttle level.
4.11 How to Test the Operator Presence Control (OPC) Switch
A three second time delay was added to eliminate clutch cycling on bumpy terrain.
To test, apply the parking brake and turn ON the blades, try lifting your feet off the
foot platform to test the Operator Presence Control switch (OPC). The engine
should kill and the blades should stop within 6-9 seconds. If not, service the OPC
system or contact your local Wright dealer.

5 Service and Adjustments
5.1 Tire Maintenance and Pressure
Excessively worn tire tread is dangerous on all hills. Replace drive tires with less than 3/32” of any tread
groove left. Use tires with the tread pattern recommended by Wright Mfg., Inc. only. Keep the tire pressure
in the drive tires between 18 and 22 psi. Higher pressures will cause the tires to have less traction, which will
force you to go slower and with less safety and give you a harder ride. Front Casters are equipped with non-
pneumatic tires and do not required any air. They do not have any tread but should be replaced when
excessively worn. Lowering the tire pressure below the recommended pressure will change the pitch of the
deck which may require further deck pitch adjustment.
5.2 Height-of-Cut
Before Adjusting the Height-of-Cut be sure of proper air pressure in rear drive tires and check for even tire
wear. Your mower is set from the factory at 3” with a ¼” forward pitch. The height-of-cut can be adjusted the
following ways:
1. Coarse Adjustment: For the coarse adjustment (1/2 inch increments) the rear motor supports
(A) and (1 inch increments) front caster arms (B) need to be adjusted up or down to achieve a
1.5”-5” deck height.
2. Fine Adjustments: For fine adjustments (1/16”-1/4”) adjust either the ¼” blade spacers, ¼”
caster “C” spacers (C) or 1/16” caster washer (D).
3. Temporary Height-of-Cut Adjustment: using the caster shims ("C" spacers) you can adjust the
blades downward
A
B
C
D
*Blade spacers can be added or removed for additional adjustment in ¼” increments. Use three blade
spacers for optimum cut.
*For optimal deck pitch use one caster spacer. Always keep the 1/16” washers above the “C” spacers to
prevent the spacers from sliding off of the caster pin.
The angle of attack of the blades should always be lower at the front. This makes the blade cut the grass
only once and saves fuel and wear on the whole mower. It also allows more efficient mowing and grass
catching or dispersal. If you mow in an area of the country where the lawn is very thick and spongy you may
have to set these two adjustments as they would appear on the grass and not on a hard surface due to the
tires “floating” up on or “sinking” down into the lawn.

5.4 Spring platform Adjustment
The factory setting is both springs set at the most forward position. The more rearward the spring position,
the stiffer the platform gets. Adjustment will be to preference of feel. The two adjustment springs should at
all times, be positioned next to each other not one forward or back more than the other. To adjust, loosen
each spring retaining bolt from the top just enough to slide it, then tighten with impact wrench. The nut may
spin using hand wrench. NOTE, do not loosen too much, if the nut falls off, the foot platform will have to be
removed to reinstall. There is an extra hole for a third spring for operators heavy enough to bottom out the
duel spring stock set up.
WARNING
5.5 Hydraulic System
Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from
getting into the system. Clean off all parts before disassembly and assembly. When any of the hydraulic
parts are disconnected or removed or when the oil is changed, air must be bled from the system. If air is
entrained in the system, loss of power, excessive heat, and damage to the hydraulic pumps may occur.
5.7 Hydro Oil Tank Check/Fill
Checking oil
• Ensure mower is on a level surface.
• Lift hinged pad and remove hex socket plug from oil level port on the back of the tank.
• Hydro oil should be at the bottom of the threads.
22

Filling oil
• Lift hinged pad and remove hex socket plug.
• Using a funnel, fill tank through oil level port until oil
reaches bottom threads of the port.
5.8 How to Move the Mower if the Engine Won’t Start
Rotate both of the hydro bypass valve levers on the side of each hydraulic pump about ½ turn
counterclockwise. It is important not to over tighten these levers. Damage may occur to the pump if this
valve is over tightened.
5.9 Bleeding Air from the Hydraulic System
Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from
getting into the system. Clean off all parts before disassembly and assembly. When any of the hydraulic
parts are disconnected or removed or when the oil is changed, air must be bled from the system. If air is
entrained in the system, loss of power, excessive heat, and damage to the hydraulic pumps may occur.
First, make sure the oil level in the reservoir is correct. The oil should be level with the bottom threads of the
oil level port. Use fully synthetic oil: Mobil1 15W-50. With the bypass valves open and the engine running,
slowly move the control levers back and forth five or six times. Now close the bypass valves and with the
engine running, slowly move the control levers back and forth five or six times. It may be necessary to
repeat the above steps until all the air is purged and the rear wheels are turning at normal speed. After
purging is complete, adjust the oil level in the reservoir if necessary.
5.10 Lubrication
Grease with No. 2 general purpose lithium base or molybdenum base grease.
•
•
•
•
•
•
Set parking brake, stop the engine and remove the key.
Clean grease fittings with a rag.
Connect grease gun to fitting and pump until grease begins to ooze out from the bearings.
Wipe off excess grease.
Do not use spray lube of any kind on choke and/or throttle cables.

5.13 Cleaning the Mower
The underside of the mower deck should be checked and cleaned twice daily and more often if the grass
being mowed is lush or wet. The entire mower should be cleaned daily at the end of the work day.
Cleaning should be done with a leaf blower or low-pressure compressed air. Wash with water only when
necessary and do not use a pressure washer or nozzle as the water can enter bearings and electrical
connections causing an electrical short, rust and corrosion. When washing with water, avoid spraying near
the hydro cap and do so when the unit has cooled down. Washing a hot machine can cause various unseen
system damage. If water is used for cleaning, immediately dry it with a leaf blower or low-pressure
compressed air and run with blades engaged for approximately 10 minutes. Once the wash is complete,
always lubricate and grease all applicable areas.

FEDERAL AND CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The United States Environmental Protection Agency (EPA), California Air Resources Board (CARB) and
Wright Manufacturing, Inc. (WMI) are pleased to explain the evaporative emission control system (EECS)
warranty on your 2011 commercial mower. In the United States, new equipment that use small off-road
engines must be designed, built and equipped to meet the Federal’s stringent evaporative emissions
standards. In California, new equipment that use small off-road engines must be designed, built and
equipped to meet the State’s stringent anti-smog standards. WMI must warrant the EECS on your
commercial mower for the period of time listed below provided there has been no abuse, neglect or
improper maintenance of your equipment.
Your EECS may include parts such as the carburetor, fuel-injection system, the ignition system, catalytic
converter, fuel tanks, fuel lines, fuel caps, valves, canisters, filters, vapor hoses, clamps, connectors, and
other associated emission-related components.
Where a warrantable condition exists, WMI will repair your commercial mower at no cost to you including
diagnosis, parts and labor.
MANUFACTURER’S WARRANTY COVERAGE:
This evaporative emission control system is warranted for two years. If any evaporative emission-related
part on your equipment is defective, the part will be repaired or replaced by WMI.
OWNER’S WARRANTY RESPONSIBILITIES:
•
•
•
As the commercial mower owner, you are responsible for performance of the required maintenance
listed in your owner’s manual. WMI recommends that you retain all receipts covering maintenance
on your commercial mower but WMI cannot deny warranty solely for the lack of receipts.
As the commercial mower owner, you should however be aware that WMI may deny you warranty
coverage if your commercial mower or a part has failed due to abuse, neglect, or improper
maintenance or unapproved modifications.
You are responsible for presenting your commercial mower to WMI’s distribution center or service
center as soon as the problem exists. The warranty repairs should be completed in a reasonable
amount of time, not to exceed 30 days. If you have a question regarding your warranty coverage,
you should contact WMI’s warranty claims department at (301) 360-9810.
GENERAL EMISSIONS WARRANTY COVERAGE:
WMI warrants to the ultimate purchaser and each subsequent purchaser that the commercial mower is:
Designed, built and equipped so as to conform with all applicable regulations; and
Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in
all material respects to that part as described in WMI’s application for certification.
The warranty period begins on the date the commercial mower is delivered to an ultimate purchaser or first
placed into service. The warranty period is two years.
Subject to certain conditions and exclusions as stated below, the warranty on emission-related parts is as
follows:
(1) Any warranted part that is not scheduled for replacement as required maintenance in the written
instructions supplied, is warranted for the warranty period stated above. If the part fails during the period of
warranty coverage, the part will be repaired or replaced by WMI according to subsection (4) below. Any such
part repaired or replaced under warranty will be warranted for the remainder of the period.

(2) Any warranted part that is scheduled only for regular inspection in the written instructions supplied is
warranted for the warranty period stated above. Any such part repaired or replaced under warranty will be
warranted for the remaining warranty period.
(3) Any warranted part that is scheduled for replacement as required maintenance in the written instructions
supplied is warranted for the period of time before the first scheduled replacement date for that part. If the
part fails before the first scheduled replacement, the part will be repaired or replaced by WMI according to
subsection (4) below. Any such part repaired or replaced under warranty will be warranted for the remainder
of the period prior to the first scheduled replacement point for the part.
(4) Repair or replacement of any warranted part under the warranty provisions herein must be performed at a
warranty station at no charge to the owner.
(5) Notwithstanding the provisions herein, warranty services or repairs will be provided at all of our
distribution centers that are franchised to service the subject engines or equipment.
(6) The commercial mower owner will not be charged for diagnostic labor that is directly associated with
diagnosis of a defective, emission-related warranted part, provided that such diagnostic work is performed at
a warranty station.
(7) WMI is liable for damages to other engine or equipment components proximately caused by a failure
under warranty of any warranted part.
(8) Throughout the commercial mower warranty period stated above, WMI will maintain a supply of
warranted parts sufficient to meet the expected demand for such parts.
(9) Any replacement part may be used in the performance of any warranty maintenance or repairs and must
be provided without charge to the owner. Such use will not reduce the warranty obligations of WMI.
(10) Add-on or modified parts that are not exempted by the Air Resources Board may not be used. The use
of any non-exempted add-on or modified parts by the ultimate purchaser will be grounds for disallowing a
warranty claims. WMI will not be liable to warrant failures of warranted parts caused by the use of a non-
exempted add-on or modified part.
WARRANTED PARTS:
The repair or replacement of any warranted part otherwise eligible for warranty coverage may be excluded
from such warranty coverage if WMI demonstrates that the commercial mower has been abused, neglected,
or improperly maintained, and that such abuse, neglect, or improper maintenance was the direct cause of the
need for repair or replacement of the part. That notwithstanding, any adjustment of a component that has a
factory installed, and properly operating, adjustment limiting device is still eligible for warranty coverage. The
following emission warranty parts listed below are covered:
