Pre-Delivery Service of Mower by Dealer
If you are not completely familiar with the Safety Instruction
Manual read it now before proceeding with the Pre-Delivery
Service of the mower. Only your authorized Wright dealer
should perform the Pre-Delivery Service of the mower.
WARNING
The Wright Stander RH is shipped completely assembled and has been adjusted and tested at the factory.
However, due to jostling during 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” under the blade belt covers, 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.
• 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.
• Check the Rapid-Hite deck height adjustment mechanism for proper operation.
• Lubricate all moving parts (see Maintenance Items section of this manual).
• 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)
With the hand controls in the middle or neutral position, apply the 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:

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.
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. 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. See the instructions in the
Recommended Maintenance section of this
manual for other items of required maintenance.
WARNING
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
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 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.
WARNING
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
WARNING
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

area without good, approved ventilation. Exhaust
fumes are dangerous.
• 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.
WARNING
• 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.
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.
• 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).
• Before climbing curbs, crossing gravel drives,
sidewalks or roads, turn off the blades and
wait for them to stop, then place deck into
transport position.
WARNING
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.
• 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.

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.
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 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.
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.
WARNING
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.
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.
WARNING
Operation on Slopes
DO NOT operate on steep slopes. 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.
Heavier operators may consider obtaining the
optional weight bar which is designed to add
weight to the front of the machine.
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. If
your mower is equipped with the optional
weight bar on the front, the mower may not
handle as well crossing slopes as without
the weight bar on the front. Weight on the
6

front of the mower reduces the traction of
the rear drive wheels and can cause the
mower to slide or nose dive down hill. Use
of the optional weight bar is determined by
the width of cut of the mower and the
operator’s weight. For 36” cut mowers,
operators over 175 pounds may prefer the
optional weight kit. For 52” cut mowers,
operators over 225 may prefer the optional
weight kit. Remember it is recommended
that operators weigh at least 120 pounds
and not more than 325 pounds. These are
general guidelines only. The mower
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.
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.
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.
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 or the Wright Mfg website for the
latest Illustrated Parts List for your equipment.
WARNING
Wright is fully concerned with your safety.
Please read the above again and again until
you fully understand the methods to promote
the safest operation possible.
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.
REMEMBER – YOUR MOWER CAN BE ONLY
AS SAFE AS THE OPERATOR.
FAILURE TO FOLLOW SAFE OPERATING
PRACTICES MAY RESULT IN
SERIOUS INJURY OR DEATH.
WARNING
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 escaping
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

How to start the mower
Inspect Mower Before Each Use
Before starting the engine
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
• 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.
• Turn fuel valve to the “ON” position.
Starting the engine

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.
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.
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.
How to drive the mower
WARNING
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

engine speed to about half of the way from idle
speed. Release the 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.
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. Do NOT step off the mower during ANY
maneuver.

panel. Make sure the control levers are in the
exact neutral position. Set the parking brake,
reduce the engine speed to idle, shut off the
ignition switch to stop the engine and then
remove the key from the ignition switch. The
mower is now parked. Do not leave mower
unattended on a sloped surface.
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.
Mowing on Varying Terrain
See the Safety Instructions section of this
manual, especially the parts on:
• Initial Operating Safety Guidelines
• Operation On Slopes
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 Reverse
• Operation In Forward Direction
• Operation During Zero-Radius Turns
• Operation In Forward Direction
Next, raise the mower deck into the highest
position for. Then 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 he
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
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 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.
control rod clockwise will shorten the control rod
and slow the forward movement of the mower
on that side. Turning the control rod counter-
clockwise will lengthen the control rod and
increase the speed of the forward movement of
the mower on that side.
Changing the Speed/Sensitivity
Adjustment
The controls are initially set with the Speed/
Sensitivity
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.
Otherwise you will wind the swivels way up the
rods and the mower will go faster but will lose
most or all of its reverse capability and then the
gap between the handlebar and the control
levers becomes excessive when at the neutral
position.
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 the
bolts that hold the control rods onto the control
lever from the current holes in the control levers
and reinstalling them and the rods into the
alternate holes. The top holes closest to the
control handles are for the faster, more sensitive
setting and the bottom holes, farthest from the
control handles, are the slower, less sensitive
setting. BE SURE THE BOLTS IN THE
CONTROL RODS ARE SECURELY IN PLACE
EACH TIME YOU REMOVE THEM. You must
then perform the Tracking Adjustment described
below.
If the rod is made longer it will increase the
forward speed capability for that side of the
mower and if the rod is made shorter 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 lengthening the left-side rod) or the
right side needs to go slower (by shortening the
right-side rod). If the mower is tracking to the
right, either the right side needs to go faster (by
lengthening the right-side rod) or the left side
needs to go slower (by shortening the left-side
rod). It is important that neither rod should be
lengthened too far, as mentioned above.
How to Perform the Tracking
Adjustment
First ensure that the tire pressure is equal on
both rear drive tires (18-22 psi) and also the
front caster tires (30-40 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. Turning the
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.
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. Keep the tire pressure in the front
caster tires between 30 and 40 psi. Higher
pressures will help keep the caster tires on their
rims when impacted from the side but give a
harder ride. They do not have any tread but
should be replaced when excessively worn.
After getting the mower to track straight, 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.
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. The
parking brake should now be applied. 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 a few 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.
Height-of-Cut
Before adjusting the height-of-cut be sure the
mower engine is off, and all four tires have
proper air pressure. Check for even tire wear.
The height-of-cut can be adjusted the following
way:
• While holding the deck lift lever grip to the left
of the upright, push down (with thumb or other
hand) on the button at the top of the deck lift
lever. With the button pushed down, pull back
slightly and then move the deck lift lever
forward to lower the deck or pull back to raise
the deck. When the deck is at the desired
height, release the button and make sure the
internal stop block is fully locked into place.
There is also a détente pin that can be used to
insure the deck is not lowered to a cutting
height that is lower than the lowest desired
cutting height.
Belt Tension Adjustment
The pump drive belt is self-adjusting, and
requires no adjustment, just replacement. The
blade drive belt is self-adjusting also and
requires no adjustment, just replacement.
How to Test the Operator Presence
Control (OPC) Switch
With the parking brakes applied and the blades
ON, 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 a few seconds. If not, service
the OPC system or contact your local Wright
dealer.
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.
WARNING
Service and Adjustments
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
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

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 level
should be between 1”-1.5” below the top of the
oil fill tube. Use fully synthetic oil: Mobil1 15W-
50. Lift the mower so that the rear wheels are
off the ground. Be careful to support the mower
so that it will not fall or tip while the system is
bled of air. 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.
Battery Service
The battery is 12 volts and is a maintenance free
battery. Charge the battery only if it will not start
the mower properly. Remove the battery from
the mower before charging. Follow the
instructions of the battery charger for proper and
safe charging of the battery.
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
electrical connections causing an electrical
short, rust and corrosion. When washing with
water, 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. 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
