ough inspection and any damage is repaired.  
See the instructions in the Recommended Main-  
tenance section of this manual for other items of  
requiredmaintenance.  
WARNING  
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 work boots with thick, textured  
tread, soft-rubber soles at all times. Hard or  
smooth soled shoes are too slippery for a good  
footing on mower platform. NEVER wear loose-  
fitting clothing which could get caught in moving  
parts. Wearing safety glasses, ear protection  
and safety shoes is advisable and required by  
some local ordinances and insurance regula-  
tions.  
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, linchpin or  
“hair” pins and replace before operating the  
mower. Make sure all safety equipment pro-  
vided 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. Ensure that all  
parts of the hand-operated transmission control  
system are tight and secure. This is to reduce  
the possibility that the mower could have a loss  
of control or safety.  
WARNING  
Work Area Conditions and 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 un-  
even ground that may be hidden in the grass.  
Clear the work area of moveable objects such  
as wires, rocks, glass, 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, stub pipes protruding from the  
ground, paving edges, etc. in the path of opera-  
tion 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 near the  
machine while in operation. Thrown objects can  
pass through glass windows and some walls of

excessive speed may cause serious  
injury.  
The discharge chute deflector must be in-  
stalled at all times and in the down posi-  
tion except that it may be raised when  
the grass catcher is completely installed.  
If the mower discharge clogs, turn off the  
blade clutch switch, apply the parking  
brakes, stop the engine and remove the  
key before removing obstruction.  
WARNING  
Initial Operating Safety Guidelines:  
Read and understand the warning on the  
instrument panel of the mower.  
Keep a firm hold on the stationary handle at  
all times.  
Keep all shields and covers in place, espe-  
cially grass discharge chute deflector, the  
blade belt cover, and the pump belt/pulley  
cover over the operator’s toe area.  
Keep hands, feet and clothing away from  
rotating parts, especially the rear wheels,  
blades, engine flywheel, belts and pul-  
leys.  
Do not touch engine or muffler 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 crossing gravel drives, sidewalks or  
roads, turn off the blades and wait for  
them to stop.  
Keep both feet on foot platform at all times.  
Know the controls and how to stop quickly.  
Before attempting to start the engine, follow  
all starting instructions.  
Look behind before backing up.  
Before leaving the operator’s position for  
momentary reasons, turn off the blade  
clutch engagement switch, 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 which would be hazardous if the  
mower were to roll.  
When transporting, driving onto transport  
vehicles, into buildings, across parking  
lots or otherwise not mowing grass, turn  
off the blade clutch engagement switch to

ate and slow down gently. If you ever go  
intoanuncontrolledslidewhilepointing  
down a slope the recommended proce-  
dure is to let go of the handles and jump  
offifnecessary.Otherwise,controlthe  
mower gently and stay off slopes that tend  
to make the wheels slide at this orienta-  
tion.  
The Wright Stander is capable of greater trac-  
tion on slopes than typical riding mowers be-  
cause of the benefits of a lower center of grav-  
ity. It is essential for you to know more about  
the handling characteristics of the mower so that  
you can enjoy more efficient mowing techniques  
and for increasing your safety.  
When crossing a slope sideways, the Stander  
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.  
The Wright Stander mower handles differently at  
different angles of attack on a slope. It is impor-  
tant to understand the following differences so  
that you can use or avoid using the mower at  
different angles for the best advantage. Be  
aware that if you do a turn on a slope you may  
go through all of the following orientations to a  
slope and must handle the mower accordingly.  
As you use the mower you will gain the tech-  
nique to mow more lawn than ever before.  
Recommendations for this angle:  
Stand straight, as far as forward and back-  
ward are concerned, but lean sideways,  
toward the uphill side and stand on the  
uphill side of the foot platform. This adds  
weight to the higher side drive wheel and  
will allow you to mow more quickly

Fuel Safety:  
Always keep a firm grip on the mower handles  
with both hands. Keep both feet firmly on the  
foot platform. Operate the mower very slowly,  
inching it backward until you become familiar  
with how the mower operates and always if in  
an awkward location or position. Never place  
your foot or feet on the ground near the back

Operation in Forward Direction:  
Always keep a firm grip on the mower handles  
with both hands. Operate the mower slowly until Keep body and hands away from pin holes or  
you become familiar with how the mower  
handles. Do not operate the mower faster than  
conditions allow. For example hills, wet or  
bumpy ground, dim light or high grass would all  
be conditions where you should work slower  
than normal. Never operate the mower at the  
highest speed unless you are on level, wide,  
open areas of clearly visible ground or trans-

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 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 the Wright mower. Hydraulic fluid  
is under high pressure. If you need service on  
your hydraulic system, please see your autho-  
rized Wright dealer.  
WARNING  
We really want you to be as safe as pos-  
sible. Please read the above again and again  
until you fully understand the methods to  
promote the safest operation possible.  
Operation During Zero-Radius Turns:  
During zero-radius turns (when one mower  
wheel rotates backwards while the other is  
moving forward) drive extra slowly to reduce the  
possibility of losing traction or control, or be-  
coming dizzy. This will help prevent you from  
being thrown off of 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 above and

REMEMBER - YOUR MOWER CAN BE ONLY  
AS SAFE AS THE OPERATOR.  
FAILURE TO FOLLOW SAFE OPERATING  
PRACTICES MAY RESULT IN  
SERIOUS INJURY OR DEATH.

factory. However, duetothejostlingoftheship-  
ping process and the amount of time elapsed  
since this was done at the factory until you re-  
ceived the machine the following items need to  
be repeated again before starting the mower.  
Afteryouhaveun-cratedthemowerfollowthese  
procedures in the order indicated:  
Fill fuel tank with regular unleaded gasoline.  
Open fuel valve under gas tank.  
Remove spark plug wire from spark plug(s)  
Inspect the mower for any damage, unusual  
conditions or missing parts.  
DO NOT START THE ENGINE AT THIS  
TIME. FOLLOW THE NEXT PROCEDURE  
BEFORE STARTING. The hydraulic sys-  
tem MUST be checked for proper opera-  
tion before allowing wheels to operate on  
the ground.  
Set the rear of the machine on jack stands or  
blocks to raise rear wheels off of the  
ground two or three inches and check that  
the mower will not fall off the supports you  
devise. (Do not support the mower's  
weight on any part of the foot platform).  
You must be able to stand on the mower.  
The stand(s) must be able to secure the  
mower from rolling off or away during the  
next procedures. Check under the mower  
deck for any debris or unusual conditions.  
With hand controls in the middle or neutral  
position, apply the parking brake.  
Inspect the mower for all of its decals, espe-  
cially the warning decals. There should be  
one blade warning decal on each side of  
the deck, the “shield missing” under the  
blade belt cover, the dash decal, the  
“shield missing” decal behind the pump  
pulley and belt guard over the operator’s  
toe area.  
Check (and fill if necessary) engine oil level  
according to the engine manufacturer’s  
recommendation.  
Check (and fill if necessary) hydraulic fluid  
level. The level should be about 3"-4"  
below the top of the oil fill. Use synthetic  
oil: Mobil 1 10W-30 or AmsOil 10W-40.  
Check rear tire pressure. 8 to 12 psi. is  
recommended. It should be even on both  
sides. Use the higher pressures for heavier  
operators. Set the tire pressure in the front  
caster tires between 35 and 46 psi. Higher  
pressures will help keep the caster tires on  
their rims when impacted from the side but  
give a harder ride.  
Remove the blade belt cover and check (and  
tighten if necessary) all belt tensions ac-  
cording to specifications further in this  
manual. DO NOT OVERTIGHTEN.  
Rotate the blade pulleys slightly to see if they  
rotate freely and all turn together.  
Open the manual valves on top of each motor  
a half-of-a-turn counterclockwise.  
Reattach spark plug wires to spark plugs.  
Before starting the engine be ready to stop it  
if the wheels begin to turn with the brake  
on.(Ifthishappens,checkthatthemanual  
valves on top of each motor are open at  
least a half-of-a-turn counterclockwise.)  
Start the engine according to the engine  
manufacturer’s recommendation. Let the  
engine run at low RPM for several minutes  
to get the hydraulic fluid circulating through  
the pumps, etc. While standing on the foot  
platform, release the parking brake. Now

Electric Start:  
Start the engine according to the engine manu-  
facturer’s recommendation, see engine  
manual. You will need to start the engine by  
turning the key on the mower’s instrument  
panel. Do not engage the starter for more  
than 10 seconds at a time. This may over-  
heat the starter and the wiring systems. Wait  
10 seconds between attempts. If the engine  
does not start within ten tries or stalls fre-  
quently take the mower in for service.  
After starting the engine according to the engine  
manufacturer’s recommendation, 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.  
Basic Operation: The following procedures are  
to guide you through the basic operation of the  
mower. You should be a qualified mower opera-  
tor according to the safety section of this manual.  
If this is your first time, this should only be done  
with the assistance of your dealer on a level area.  
You should go through each step, in the order  
indicated, everytimeyoustartthemower.  
Be Aware Of Unusual Noises or Ir-  
regular Operation  
As you drive the mower listen for any unusual  
noises and test for irregular operation and adjust  
or service as necessary.

Adjustment,furtherdescribedbelow.  
If the rod is made shorter it will speed up 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 rod)  
or the right side needs to go slower (by length-  
ening the rod). And, if the mower is tracking to  
the right either the right side needs to go faster  
(by shortening the rod) or the left side needs to  
go slower (by lengthening the rod). It is impor-  
tant that neither rod should be shortened too far  
as mentioned above.  
How to Perform the Tracking and  
Neutral Adjustment  
The only reference point to limit the adjustment  
from becoming extremely off is the relative  
position of the pump internal stop and the sta-  
tionary bar in the faster Speed/Sensitivity set-  
ting. 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 to be accu-  
rate and then change to the slower speed range  
and tweak the tracking only one or two turns on  
either side.  
First ensure that the tire pressure is equal on  
both rear drive tires. Drive the mower on a level  
parking lot with 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 removing the "hair  
pin" from one or the other of the swivel ends at  
the lower ends of the control rods and screwing  
the swivel to either make the control rod longer or  
shorter. Beforechangingthelengthoftherods  
several facts are important to know:  
BE SURE THE “HAIR” PINS IN THE SWIVEL

should be shortened so much that at full speed it

between 8 and 12 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 35 and 46 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.  
How to Test/Use the Blade Clutch/  
Brake Switch  
Hydraulic Motor Support Adjustment  
The various holes in the tractor frame and the  
hydraulic motor supports may be used to make  
a fine forward/rearward adjustment to the  
balance of the Stander. This adjustment should  
always be made in combination with the coarse  
height-of-cut adjustment and anti-tip roller ad-  
justment as described below. When the motor  
supports are set in the forward position, the  
Stander will be balanced lighter in the front than  
when set in the rearward position, giving more  
traction to the drive tires. Heavy operators (over  
250 lbs. or so) may find that the rearward  
position helps keep the front of the mower  
down.  
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 the highest RPM speed set-  
ting. (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.)  
Stand 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. Under mowing  
load, the clutch's longevity will be the greatest at  
the highest RPM setting.  
Blade Adjustments and Height-of-Cut  
Before Adjusting the Height-of-Cut be sure of  
proper air pressure in all four tires and check for  
even tire wear. The height-of-cut can be ad-  
justed the following ways:  
Coarse Adjustment: For the coarse adjust-  
ment the rear wheels, the front casters and  
the anti-tip rollers should be adjusted at the  
same time. Adjust the rear wheel motor  
supports equally in one of the three settings  
up or down 0.75" each in a 1.5" total range.  
a. Use the highest holes in tractor frame  
for cutting heights of 1.75" - 3.0".  
How to Test the Operator Presence  
Control (OPC) Switch  
With the parking brakes applied and the blades  
ON, try stepping 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.  
b. Use the middle holes in tractor frame  
for cutting heights of 2.5" - 3.75",  
factory setting.  
c. Use the lowest holes in tractor frame  
for cutting heights of 3.25" - 4.5".

The anti-tip rollers at the back end of the  
mower must be adjusted to correspond to  
the above holes used for the coarse

five settings up or down 0.25" each in a 1.25"  
total range. The shims on the blade bolts are  
moved from under the spindle to the top of the  
spindle. If possible, leave at least one shim at  
the top and the bottom of the spindle shaft.  
Usingthemaximumsandminimumsofthese  
methods gives you a total range of 2.75" from  
1.75" to 4.5" in eleven distinct settings. The  
factory setting is 3" when measured to a hard  
floor surface at the front of the deck.  
Use the higher holes for the anti-tip roller for  
motor supports in highest holes in tractor  
frame, setting "a" above.  
Use the lower holes for the anti-tip roller for  
motor supports in middle or lowest holes  
in tractor frame, settings "b" or "c" above.  
Adjust the front caster arms at their respec-  
tive support brackets equally in one of the  
seven settings up or down 0.25" each  
through a 1.5" total range.  
Belt Tension Adjustment  
The pump drive belt is self-adjusting, and nor-  
mallyrequiresnoadjustment,justreplacement. It  
is spring loaded to prevent strain on the pump  
bearings. However, there are three holes for  
locating the bolt where the spring attaches for  
increasing the spring tension. Factory setting is  
the hole to the right side of the mower which is  
the least tension. The blade drive belts should  
be tightened only so that you can deflect the belt  
about 1/2 inch when pushing 8 lbs. with your  
thumb. DO NOT OVER TIGHTEN OR THE  
SPINDLE AND IDLER BEARINGS WILL WEAR  
PREMATURELY OR YOU COULD DAMAGE  
THEENGINEBEARINGS. Thisadjustment  
should be checked at forty (40) hour intervals  
except new belts should be checked every four  
(4) hours for the first twenty (20) hours. A loose  
belt will not cut grass, will run hot and wear  
prematurely.  
a. This should be done with two shims (or  
"C" spacers) on the bottom and one  
shim on the top of the caster support  
arm.  
b. The front-to-rear leveling of the blades  
should be between level (preferred)  
to .25" lower at the front of the blades  
but never higher at the front.  
c. Use the lowest holes in tractor frame  
for heights of 3.25" - 4.5".  
Temporary Height-of-Cut Adjustment: using  
the caster shims (or "C" spacers) you can  
adjust the blades downward temporarily .5"  
or 1" below the original coarse setting as  
described above. This assumes that the  
blades are level with two shims (or "C"  
spacers) on the bottom and one shim on the  
top of the caster support arm. With the  
blades level at this assumed starting point,  
you should never move all of the shims to the  
bottom since that would make the blades  
higher at the front.  
How To Move The Mower If The En-  
gine Won’t Start  
Rotate both of the manual “dump” valve levers  
on the top of each hydraulic pump about 1/2 turn  
counterclockwise. Tighten the valves again  
The angle of attack of the blades should  
always be level or lower at the front. This before starting the mower again.

mower. It also allows more efficient  
mowing and grass catching or dispersal.  
If you mow in an area of the country  
where the lawnis very thick and spongy  
you may have to set these two adjust-  
ments 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.

the top of the oil fill. Use synthetic oil: Mobil 1  
10W-30 or AmsOil 10W-40. Whenever servicing  
the hydraulic system, it is of the utmost impor-  
tance to keep any dirt or debris from getting into  
the system. Clean off all parts before disassem-

Maintenance Service Intervals  
It is very important to keep good maintenance records. Use the hour meter on the mower and record  
the hour reading of each maintenance service so you will not forget how long it has been since you  
last did certain maintenance. The more faithful and consistent you are, the longerthe mowerwill  
last and slower it will depreciate.
