PRE-DELIVERY SERVICE OF MOWER BY DEALER
WARNING
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.
The Wright ZTO 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, raise and lock the ROP’s to the upright position.
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 service, parts and recall bulletins to ensure unit does not need any updates.
Check (and fill if necessary) engine oil level according to the engine manufacturer’s recommendation.
Check hydraulic expansion tanks oil levels. Use motor oil: 20W-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.
Check the “Quick Cut Height” deck adjustment system for proper operation.
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.
Put the control handles in the”Drive” (handles in) position, this releases the internal parking brake. Try
starting the engine. (Engine should not start. If engine starts, service the parking brake locking system)
Apply parking brake by moving the control handles to the “Park/Brake” (Handles out) position.
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 transaxles, etc.
Release the parking brake by moving the control handles to the drive position. 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.
Move the control handles to the “Inward” operational position.
2
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 4-7
seconds after leaving the seated position. 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:
Register the mower online within 14 days from the date of retail purchase.
(If unable to use the online registration process, contact your Distributor to
register for you)
Registering the product indicates you have successfully completed the pre-delivery
service checklist.

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.
1.8 Inspect the Mower Before Each Use
WARNING
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, control system ball joints 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
seat-operated Operator Presence Control (OPC) switch is released. (To test the OPC, follow instructions in
the Operating Instructions section of this manual.) 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.
1.9 Regular Mower Safety
WARNING
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. Make sure the chute deflector is always in
6
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.
1.10 Work Area Conditions and Inspection
WARNING
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 possibly throw you into
the control levers or even off the mower, 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 nearby. 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. Never operate the mower in an enclosed area without
good, approved ventilation. Exhaust fumes are dangerous.

WARNING
Read and understand the warnings on the general warning decal on the mower.
Regularly check and test the safety devices for correct function.
Recommended PPE is safety shoes, safety glasses and ear protection.
Use seat belts with the roll bar in the raised and locked position.
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 seat, even momentarily, turn off the blade clutch engagement switch and
move the control handles to the outward “Park/Brake position. 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, move the control
handles to the Park/Brake position, stop the engine and remove the key. Never leave the machine
unattended on a slope in case someone moves the control handles to the inward (Brake Off) position. This
could create a rollover hazard.
When transporting, driving onto transport vehicles, into buildings, across parking lots or otherwise not
mowing grass, raise deck and lock in the transport position and turn off the blade clutch engagement
switch to reduce risk of thrown objects and rotating blade hazard. After coming to a stop, move the
controls to the Park/Brake position, stop the engine and remove the key.
Before performing any maintenance or repair service, disengage power to blades, 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.
7
• 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, move the control levers to the
Park/Brake position, 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 transaxle 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, and then place deck into transport position.
• Inspect/Deploy/Packout ROP’s prior to operation. Additional operational safety guidelines with regards to
the ROP’s may also be found in this manual.
1.12 Safety for Maintenance
WARNING
• Repairs carried out by untrained or unauthorized personnel may result in personal injury or serious
malfunction of the ZTO.
• If Guarding is removed for inspection and component replacement, ensure the control levers are in the
Park/Brake position and the key is removed prior to inspecting or making repairs and that the guarding is
replaced before operation.
1.13 Operation in Forward Direction
WARNING
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.
1.14 Operation in Reverse
WARNING
Keep both feet on the foot platform at all times. 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. The control system is
equipped with a return to neutral from reverse spring. This is to aid the operator in returning the mower to
neutral after a reverse maneuver.
1.15 Zero-Radius Turn Operation
WARNING
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 or into the control levers. 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.
8
1.16 Operation on Slopes
WARNING
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. DO NOT mow near drop-offs or near water. Keep the roll bar in the raised and locked
position and use seat belt. 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. The operator is responsible for safe operation 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 in the seat as possible to shift 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:
• Sit back as far as you can on the seat. This adds more of your body weight to the 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, 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:
• Sit back, as far as you can on the seat and angle yourself to the higher side. This adds weight to the rear
drive wheels and will allow you to mow more quickly across the slope without sliding. Remember it is
recommended that operators weigh at least 120 pounds and not more than 350 pounds. 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. The front caster tires do not require air.
1.17 Fuel Safety

5 OPERATING INSTRUCTIONS
WARNING
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.
5.1 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 seat-operated Operator Presence Control (OPC) switch is released. To test the OPC, follow
the instructions given later in this manual. Ensure that all parts of the control-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.
5.2 How to start the mower
Before starting the engine
• Make sure the control levers are in the Parked/Brake, outward position
• Turn OFF the blade engaging switch if it is on.
• Turn fuel valve to the Left or Right, depending which tank you
choose to use. Note: The fuel valve is located on the left side, rear
of the seat frame.
Starting the engine
•Start the engine according to the engine manufacturer’s recommendation, see engine manual. Set the throttle
control lever near mid throttle. Set the choke lever to full choke. Turn the key to the start position. Do not
engage the starter for more than five (5) 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, pull back on the choke
control knob to open the choke valve, let the engine run for 3-5 minutes at mid throttle to allow sufficient warm
up. Do not over-rev a cold engine.
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.
5.3 How to drive the mower
WARNING
While sitting, 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 by moving the control handles to the “In” position. 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. With both feet still firmly placed on the foot
platform, increase the engine speed to about half of the way from idle speed. 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
17
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.
5.4 How to Stop and Park the Mower
Come to a complete stop. If the blades are on, turn them off using the blade switch on the instrument panel.
Make sure the control levers are in the outward position, parked/brake on. Reduce the engine speed to idle
and let run for 3-5 minutes, 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.
Parked / Brake On
5.5 Driving the Mower Over a Curb
WARNING
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
Next, raise the mower deck into the locked transport position. This is the highest position for the mower deck.
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 rear
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.
Do NOT step off the mower during ANY maneuver.
5.5.1 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.

5.6 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
5.7 How to Adjust Neutral
Neutral refers to the mower movement when the engine is set to full throttle, control handles are moved to the
inward/operate position and 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
A
transaxle has a Return-to-Neutral (RTN) device built into the
linkage of the assembly for reverse only. Before adjusting
neutral, it is necessary to lift the rear drive wheels off the
ground using a jack and stands. Additionally, the OPC seat
switch will need to be engaged. To make the adjustment,
remove the rear tire and remove the control rod at the
transaxles control arm. (Fig. 1, A) Loosen the ¼” Allen bolt
(Fig.1, B) and rotate the RTN device on the pump
corresponding to the wheel that needs adjustment. If the
B
right wheel turns in the neutral position, then the right
transaxle 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
Figure 1
allen bolt. Repeat the procedure on the other transaxle if
necessary.
5.8 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 (Fig. 1, Transaxle) (Fig.2, Control Handle) (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
front and rear of the control rod proceed to turning the control rod clockwise or counter-clockwise to lengthen
or shorten the effective length of the control rod.
Figure 2
Figure 1
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. Therefore, 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.
19
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.
5.9 How to Test/Use the Blade Clutch/Brake Switch
WARNING
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. Sit evenly on seat and keep 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.
5.10 How to Test the Operator Presence Control (OPC) Switch
With blades ON, try lifting your weight off the seat to test the Operator Presence Control switch (OPC). The
engine should begin to kill after a ½ second delay and the blades should stop within a few seconds. If not,
service the OPC system or contact your local Wright dealer.

6 SERVICE AND ADJUSTMENTS
6.1 Tire Maintenance and Pressure
WARNING
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. Lowering tire pressure will affect deck pitch. Always check pitch
any time tire pressure is set below recommended pressures. 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. The front
casters are equipped with non-pneumatic tires and do not require any air. They do not have any tread but
should be replaced when excessively worn.
20
6.2 Height-of-Cut
Before adjusting the height-of-cut be sure the mower
blades are off, and the rear tires have proper air pressure.
Detent Pin
Check for even tire wear. The height-of-cut can be
adjusted the following way:
• The cut height is set by allowing the foot lever to rest on
a detent pin inserted into the height selection plates. To
set the height of the pin, raise the mower deck to the
transport height position and lock in. This is achieved
Locking
by pressing the pedal all the way forward until the latch
Latch
system engages the pedal and locks the deck up in the
Mechanism
Deck Lift System
transport position. With the load removed from the
detent pin, it can be changed to the desired cut height.
Once the pin is securely connected to the selector plate,
the deck can be lowered to the desired cutting height by pressing in on the deck-lift foot pedal until the latch
releases the pedal. Now the deck can be lowered until it comes in contact with the pin.
6.2.1 Deck Lift Spring Assist Adjustment
To adjust the deck lift assist spring, raise the deck to the up and locked (transport) position. Remove spring
from the front spring attachment. Remove and reinstall in the upper hole (less tension) and lower hole (more
tension). Reinstall spring to front attachment.
6.2.2 Deck Adjustments
The mower deck can be adjusted for pitch and side-to-side levels. Pitch is the relationship between the front off
the blade and the rear of the blade in regards to the height of the cut. A positive pitch (front of the blade is
lower than the rear of the blade) of ¼” is the optimum setting.
Each of the four chain hangers connecting the mower deck to the lift assembly has an adjustable pivot plate
located on the top of the mower deck. On a flat and level surface, the pitch and side-to-side variation should be
checked regularly. Note: it is necessary to have a front to rear pitch of 1/4 inch aiming the front of the deck
toward the ground. Adjust one side at time when setting deck height adjustment.
If the deck is leaving stripes, it may be necessary to check the adjustment on the four deck hangers.

with limited grease fittings therefore only the front castor wheels and
caster pivots need to be greased. (See maintenance chart for service
intervals)
• Caster Pivots - Remove dust cap, cotter pin and hex nut.
Inspect grease seal and bearings. Fill chamber with grease and
reinstall in reverse order.
• Caster Wheels – Wipe grease zerk with clean rag, using grease
gun, pump in several pumps per side, weekly.

WARNING
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 transaxles may occur.
6.7 Transaxle Fluid Change Procedure
WARNING
To ensure constant fluid quality levels and longer life, an initial oil and filter change at 75 – 100 hours, then
every 400 hour thereafter is recommended.
Work on a level surface and move control levers to the outward “Park/Brake On” position.
1. Remove filter guards from both transaxles. (a)
2. Clean any loose debris from around the filter. It is very important that no dirt or contamination enter the
hydraulic system.
3. Remove filters and allow oil to drain from the drive system.
4. After the oil has drained, wipe the filter base surface off and apply a film of new oil to the gasket of the
new replacement filter (Wright Mfg. P/N 39410007).
5. Install filters by hand, turn ¾ to one full turn after the filter gasket contacts the filter base surface.
6. Reinstall the filter guards and torque screws to 65 In lbs (7.3 Nm) each.
7. Relieve drive belt tension and remove belt from stationary pulley. (b)

6.8 Transaxle Purging Procedure
WARNING
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. Open both bypass valves (see section 6.5). Start the machine and
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. When the transaxles
operate at normal noise levels and moves smoothly forward and reverse at normal speeds, then the
transaxle is considered purged. After purging is complete, close both bypass valves and adjust the oil level
in the reservoir if necessary.
6.9 Battery Service
WARNING
The battery is 12 volts and is a maintenance free battery. Charge the battery only if it will not start the
mower effectively. Remove the battery from the mower before charging. Follow the instructions of the
battery charger for proper and safe charging of the battery. Always make sure the Positive terminal is
connected to the Positive battery post and the Negative terminal is connected to the Negative battery post.
Reversal could cause damage to the electrical system.
•
Keep the battery and terminals clean.
•
Keep battery bolts tight.

6.12 Loading and Unloading
WARNING
Use extreme caution when loading or unloading units on/off trailers or trucks. One full width ramp that
extends beyond the rear tires is recommended rather than individual ramps for each side of the unit. The
ramp should be long enough so that the angles between the ramp and the trailer or truck does not exceed
15 degrees. A steeper angle may cause the mower deck components to get caught as the unit moves from
ramp to trailer or truck. Always put the deck in the transport (up & locked) position when loading or
unloading. Never attempt to turn the mower around on the ramp. Avoid sudden acceleration when driving
up a ramp and sudden deceleration when backing down a ramp.
6.13 ROP’s Installation & Operation – P/N 98410135
IMPORTANT when using a ROPS:
1. DO NOT cut, drill, modify or repair ROPS in any manner.
2. Always replace a damaged ROPS.
3. Always use the seatbelt and ROPS together.
4. Frequently inspect roll bar and seat belts for damage or loose hardware.
5. Use extreme care when working close to fences, ditches, trees and on hills.
6. Check overhead clearances carefully before driving under any objects.
7. DO NOT leave operator’s position while unit is running.
8. DO NOT carry riders.
25
9. If ROPS is a folding ROPS, ROPS should be in the upright position and pinned when operating the
machine.
10. See General Safety Information below;
This symbol means ATTENTION! YOUR SAFETY IS INVOLVED. The message that
follows the symbol contains important information about safety. Carefully read the message.
This Roll Over Protective Structure (ROPS) has been certified to industry and/or government
standards. Any damage or alteration to the ROPS, mounting hardware, or seat belt voids
the certification and will reduce or eliminate protection for the operator in the event of a rollover. The ROPS, mounting hardware, and seat belt should be checked after the first 100
hours of machine operation and every 500 hours thereafter for any evidence of damage,
wear, or cracks. In the event of damage or alteration, the ROPS must be replaced prior to
further operation of the machine.
The seat belt must be worn during machine operation when the machine is equipped with a
certified ROPS. Failure to do so will reduce or eliminate protection for the operator in the
event of a roll-over.
Substitution of mounting hardware, seat belt, etc, with components not equal or superior to
the original certified components will void the certification and will reduce or eliminate
protection for the operator in the event of a roll-over.
All labels, caution decals, ROPS certification data, etc. must be kept intact and legible.

6.17 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.

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.
36
(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.

Mowing Tips
Always mow at full throttle
Check deck pitch, front blade tip MUST be 1/4" - 3/8" lower
than the back of the blade tip.
Cut 1/3 of the grass blade, cutting more is not
recommended unless grass is sparse
Use a slower ground speed when grass is wet and lush or
when using a mulch kit.
Clean the under side of the cutter deck after each use.
Grass build up WILL eventually effect cut quality.
