WARNING
PRE-DELIVERY SERVICE OF MOWER BY DEALER
Before proceeding with the Pre-Delivery Service of your mower,
please read the safety instructions manual in its entirety. Only your
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.
authorized Wright dealer should perform the Pre-Delivery Service of
the mower.
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:

1.5 Safety for Operation
The ZTO should only be used by fully trained operators to prevent the risk of injury to themselves or other
personnel. The owner’s/user’s obligation is to instruct themselves and all potential users in the safe
operation of this equipment and be sure they read and follow the instructions in this safety manual and other
material provided by Wright Manufacturing, Inc. before using or allowing others to operate the equipment.
DO NOT operate this unit unless you carefully read, understand and follow the operation and safety
instructions contained in this manual and the warning decals provided on the unit. DO NOT allow other
persons to use this unit unless you make sure they carefully read, understand and follow these instructions.
Never allow children to operate or play on the unit.
1.6 User Qualifications
This product is designed for use by physically fit, experienced, professional commercial mower operators
who have a minimum of 160 hours of experience operating twelve horsepower and greater industrial
mowers. Operators must be 18 years or older and weigh at least 120 pounds and no more than 350
pounds. They must have read and understood this manual. DO NOT allow children to operate the mower.
Never allow passengers on the mower. DO NOT allow adults to operate the mower without proper
instruction as mentioned above.
1.7 User Clothing
DO NOT operate the mower while wearing sandals, tennis shoes, sneakers, or shorts. Always wear long
non-baggy pants. Wear high-top leather steel-toed work boots with thick, textured tread, soft-rubber soled at
all times. Hard or smooth soled shoes are too slippery for a good footing on mower platform. NEVER wear
loose-fitting clothing or jacket pockets that can get caught on the handlebars or control levers of any mower
you drive. Wearing safety glasses, ear protection and safety shoes is advisable and required by some local
ordinances and insurance regulations.
1.8 Inspect the 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, 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
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
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.
1.11 Initial Operating Safety Guidelines
• 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
WARNING
• 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
• 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
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
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
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
WARNING
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
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.
