Pre-Delivery Service of Mower by Dealer
WARNING
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.
The Wright Stander ZK 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 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 (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 to 22 psi. is recommended. It should be even on both sides. 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 cutter deck for proper adjustment. The deck should be approximately ¼” lower in the front than
in the rear and the deck should be level side-to-side. If the deck is not adjusted properly, please adjust at
this time. See Deck adjustments section of this manual for further instructions.
• Lubricate all moving parts (see Maintenance Items section of this manual).
• Add regular unleaded gasoline to fuel tank. Turn fuel valve, located on the right side of upright to the “ON”
position. The down position controls the right tank, the up position controls the left tank. Center position is
“OFF”. (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.
o Try starting the engine with the parking brake released. (Engine should not start. If engine starts,
service the parking brake locking system)
o With 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.
o 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.
5
• 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. ZK’s are being set at the factory at the 12 MPH setting
of the Speed/Sensitivity Adjustment. (See further in this manual for information on Speed/Sensitivity
Adjustment)(Ground speeds are estimates and could vary from machine to machine plus or minus
1.0 – 0.5 mph.) Be sure that the mower drives in a straight line when both hand controls are held to the
full speed position which is up against the stationary control bar. If not, see further in this manual for
information on tracking adjustment.
• As you drive the mower, listen for any unusual noises and test for irregular operation and adjust or
service as necessary. Next, go over the safety information and operating procedures in this
manual with the customer. Instruct the customer in proper operation and observe the
customer during their initial operation on a level parking lot. Make sure 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.
The limited warranty is considered invalid unless the unit is registered and the above
steps are taken.
Remember, the purchaser is both your customer and our customer and his/her
satisfaction is very important. Thank you for supporting our products.

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 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 transmission
control system are tight and secure. This is to reduce the possibility that the mower could have a loss of
control or safety.
9
WARNING
1.8 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
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.
1.9 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, etc. that might be picked up by the mower and dangerously
thrown. Remove, if possible, or mark the location of all immovable objects or irregular areas and be sure
not to hit them with any part of the mower, its deck or the blades. Obstacles such as holes, abrupt changes
in ground contour, tree trunks, stumps or roots, pipes protruding from the ground, paving edges, etc. in the
path of operation can abruptly turn or stop the mower. This could throw you off the mower or into and
possibly over the handle bars causing serious injury or death. The faster you are moving, the more
potential there is for injury. Mow only in daylight or in good artificial light. Keep away from drop-offs, the
edges of ponds, streams, pools, etc. especially at the bottom of slopes. Do not mow when children or
others are around. When the Wright mower is in use, never direct the grass discharge toward bystanders,
traffic, cars or buildings nor allow anyone within 50 feet of the machine while in operation. Thrown objects
can pass through glass windows and some walls of buildings. There is extreme risk of danger from thrown
objects or being cut by the blades of the mower or being run over if you lose control. Never operate the
mower in an enclosed area without good, approved ventilation. Exhaust fumes are dangerous.
1.10 Initial Operating Safety Guidelines

•
•
WARNING
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 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 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.
10
• Before performing any maintenance or repair service, disengage power to blades, apply the parking
brake, stop the engine, remove ignition key and spark plug wire from spark plug(s).
• All operators of this mower should exercise caution when driving this mower at high speeds. Sudden
stops from excessive speeds may cause serious injury.
• DO NOT allow inexperienced people to operate the mower until they have read and understood these
safety instructions. Operate the mower at slower speeds while becoming familiar with it.
• The grass discharge chute deflector must be installed at all times and in the down position except that it
may be raised when the grass catcher is completely installed or a mulch kit is completely installed.
• If the mower discharge clogs, turn off the blade clutch switch, apply the parking brake, stop the engine and
remove the key before removing obstruction.
• Keep all shields and covers in place, especially grass discharge chute deflector and the blade belt covers.
• Keep hands, feet and clothing away from rotating parts, especially the rear wheels, blades, engine
flywheel, belts and pulleys.
• 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 climbing curbs, crossing gravel drives, sidewalks or roads, turn off the blades and wait for them to
stop, then place the deck into transport position.
1.11 Safety for Maintenance
WARNING
• Repairs carried out by untrained or unauthorized personnel may result in personal injury or serious
malfunction of the Stander ZK.
• If Guarding is removed for inspection and component replacement, ensure the parking brake is applied
and key is removed prior to inspecting or making repairs and that the guarding is replaced before
operation.
1.12 Operation in Forward Direction
WARNING
Always keep a firm grip on the mower stationary handlebar with both hands. Operate the mower slowly until
you become familiar with how the mower operates. Do not operate the mower faster than conditions allow.
For example, hills, wet or bumpy ground, dim light or high grass are all conditions requiring slower speeds.
Never operate the mower at the highest speed unless you are on level, wide, open areas of clearly visible
ground or transporting on paved areas. Speeding with any mower is dangerous, and so is traveling faster
than conditions should permit on this mower. Sudden stops from excessive speed or falling off the mower
may cause serious injury or death.
1.13 Operation in Reverse
WARNING
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.
1.14 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
11
you from being thrown off the mower. Be aware that if you do a turn on a slope you may go through all of
the orientations to a slope mentioned below and must handle the mower accordingly.
1.15 Operation on Slopes
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. There is a danger of suddenly sliding sideways or down the hill. When operating on
a slope, travel across the grade whenever possible, not in an up or down pattern. Reduce speed and
exercise extreme caution on slopes and in sharp turns to prevent tipping or loss of control. Be especially
cautious when changing direction on slopes.
When pointing up a slope, your mower has the most weight on the drive wheels and therefore the most
traction at the tires. However, this is the angle that it has the most tendency to tip back (“pop a wheelie.”)
This is the preferred angle for mowing small areas of steeper slopes.
Recommendations for this angle:
• Lean as far forward as possible to add your weight to the front of the mower.
• Accelerate gently. Do not accelerate quickly to avoid “popping a wheelie”.
• If backing down the hill, do not stop suddenly but slow down gradually.
When pointing down a slope, your mower has the least weight on the rear drive wheels and therefore the
least traction at the tires. This is the angle that the mower has the most tendency to slide. However, this is
the angle that it has the least tendency to tip back. Avoid this angle, as it has the least advantage for your
mower.
Recommendations for this angle:
• Lean back with arms stretched out straight while holding onto the stationary handlebar. This transfers
more of your body weight to the rear drive wheels for more traction.
• Do not change speed suddenly to minimize the tendency of going into a slide. Accelerate and decelerate
gently. If you ever go into an uncontrolled slide while pointing down a slope the recommended procedure
is to let go of the handles and jump off if necessary. Otherwise, control the mower gently and stay off
slopes that tend to make the wheels slide.
When crossing a slope sideways, your mower has the average amount of weight on the drive wheels
versus the front wheels, similar to level ground. However, this angle leaves the least weight on the higher
side drive wheel, tending to make it slip. This is the preferred angle for mowing large areas of gentle slopes.
Recommendations for this angle:
• Stand straight, 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 across the slope
without sliding.
• 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.

1.16 Fuel Safety
WARNING
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.
WARNING
1.17 Hydraulic Safety
Keep body and hands away from pin holes or fittings that eject hydraulic fluid under high pressure. Use
paper or cardboard and not hands to search for leaks. Hydraulic fluid 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 your Wright mower. Hydraulic fluid is under
high pressure. If you need service on your hydraulic system, please see your authorized Wright dealer.
1.18 Using a Spark Arrester
The engine in this machine is not equipped with a spark arrester muffler. It is in violation of California Public
Resources Code Section 4442 to use or operate the engine on or near any forest-covered, brush-covered, or grass
covered land unless the exhaust system is equipped with a spark arrester meeting any applicable local or state laws.
Other states or federal area may have similar laws.
1.19 Replacement Parts
Use of parts other than specified parts supplied by Wright Manufacturing, Inc. may compromise the safe use
of the mower, are not recommended and their use could void the warranty. Always check with your Dealer
or the Wright Mfg website for the latest Illustrated Parts List for your equipment.
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.

5.0 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 foot-operated Operator Presence Control (OPC) switch is released. To test the OPC,
follow the instructions given later in this manual. Inspect the two anti-tip rollers and their respective bolts at
the rear of the mower for tightness and proper operation. Ensure that all parts of the Quad-Lever™ control
system are tight and secure. This is to reduce the possibility that the mower could have a loss of control or
safety.
Basic Operation: The following procedures are to guide you through the basic operation of the mower.
You should be a qualified mower operator according to the safety section of this manual. If this is
your first time, operation should only be done with the assistance of your dealer on a level area.
You should go through each step, in the order indicated, every time you start the mower.
5.2 How to Start the Mower
Before starting the engine
• 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
Electric Start:
•Start the engine according to the engine manufacturer’s recommendation, see engine manual. Set the
throttle control lever near mid throttle, pull out on the choke control knob and turn the key to the start
position. Do not engage the starter for more than ten (10) seconds at a time. This may overheat the
starter and the wiring systems. Wait ten (10) seconds between attempts. If the engine does not start
after several attempts or stalls frequently, take the mower in for service.
After starting the engine according to the engine manufacturer’s recommendation, push in on the choke
control knob to open the choke valve, let the engine run for several minutes to get the hydraulic fluid
circulating through the pumps, etc. and to allow the engine to warm up. Do not over-rev a cold engine.
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
While standing, both feet should be firmly placed on the foot platform. Set the engine speed about a fourth
of the way from idle. Release the parking brake. Now try moving the hand control levers, one at a time,
very slightly, forward and backward. Check to see if the wheels move forward and backward according to
20
the position of the levers. If not, check to see that the pump release valves are closed. With both feet still
firmly placed on the foot platform, increase the engine speed to about half of the way from idle speed. 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.
5.4 How to Stop and Park the Mower
Come to a complete stop. If the blades are on, turn them off using the switch on the instrument panel.
Make sure the control levers are in the exact neutral position. Set the parking brake, reduce the engine
speed to idle, 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.
Brake OFF
Brake ON
5.5 Driving the Mower Over a Curb
WARNING
To climb a curb, first see the Safety Instruction Manual 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 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 rightrear wheel, then the left rear wheel.
21
5.5.1 Never Drive Straight Onto or Off a Curb
WARNING
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 Instruction Manual 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, 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. To make the adjustment, loosen the ¼” allen bolt
and rotate the RTN device until the neutral position is found and
then retighten the ¼” allen bolt. Use care not to over tighten the
allen bolt.
A
5.8 Changing the Speed/Sensitivity Adjustment
The WZK has three Speed/Sensitivity settings. The settings are changed by removing the control rod at the
control levers and inserting into the alternate holes.
Slow Hole
10 MPH
Factory Setting
12 MPH
Fast Hole
13.5 MPH
The controls are initially set with the Speed/ Sensitivity adjustment in the 12 MPH position. With operators
not completely familiar with the mower operation the operator may desire to leave the controls in the factory
setting or move to the slow hole position until becoming familiar with the operation. The faster setting has a
corresponding increase in the sensitivity of the controls. In other words, a given amount of movement of the
control levers will cause about a 10-15% increase in the ground speed making the controls more sensitive.
After stopping the engine, the adjustment is made by removing rod ends connected to the control rods from
the current holes in the control levers and reinstalling them into the alternate holes. The holes closest to the
operators position are for the faster, more sensitive setting and the holes farthest from the operators position
are the slower, less sensitive setting. You must then perform the Tracking Adjustment described below.
22
5.9 How to Perform the Tracking Adjustments
WARNING
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 which is up against the stationary control bar. If not, park the mower and stop the
engine. Before proceeding to adjusting the mower tracking, check and make sure both controls move freely
through the forward and reverse range. Make sure that debris has not hindered the movement of the upper
and lower control rods and linkages. If all control linkages move freely and mower tracking is off, proceed to
the next step.
5.9.1 Tracking in the 10 & 12 MPH Setting
It is essential to start with the lower (and shorter) control rods located near the pumps. With the control
levers in the neutral position, the right and left lower control rod should be adjusted to allow their respective
torsion bar to remain level at the end connected to the lower control rod. Specifically, with the pump in the
Return-To-Neutral position, the lower rod end should be the same height as the rigidly fixed ball joint
connected on the same end of the torsion rod. NOTE: This adjustment may not be necessary if tracking is
slightly off. Upper control rods should be the only adjustment required. Perform this adjustment on both the
right and left side. Now that the lower end of both torsion rods are set, proceed to the upper control rods
connected to the control levers.
Loosen the jam nuts on both ends of the upper control rod. Note: the Speed Sensitivity setting on both
sides should be set together in the middle hole (factory) position. Rotate control rod to either lengthen or
shorten. So, if the mower is tracking to the left, either the left side needs to go faster (by lengthening the
upper control rod on the right) or the right side needs to go slower (by shortening the upper control rod on
the left). If the mower is tracking to the right, either the right side needs to go faster (by lengthening the
upper control rod on the left) or the left side needs to go slower (by shortening the upper control rod on the
right).
5.9.2 Tracking in the 13.5 MPH Setting
It is essential to start with the lower (and shorter) control rods located near the pumps. With the control
levers in the neutral position, the right and left lower control rod should be adjusted to allow their respective
torsion bar to remain level at the end connected to the lower control rod. Specifically, with the pump in the
Return-To-Neutral position, the lower rod end should be at the same height as the rigidly fixed ball joint
connected on the same end of the torsion rod. Perform this adjustment on both the right and left side. Now
that the lower end of both torsion rods are level, proceed to the upper control rods connected to the control
levers.
Loosen the jam nuts on both ends of the upper control rod. Note: the Speed Sensitivity setting should be set
to the fast position. Before changing the length of the control rods several facts are important to know.
In the faster Speed/Sensitivity setting neither control rod should be shortened so much that at full speed it
pulls the pump control lever (on the sides of the pumps) against the pump’s internal stop. The pumps have
an internal stop that is not designed to take this type of force and could eventually cause pump leakage or
other damage to the pump. 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 stop has been contacted with the
control handles in the maximum forward position. Then shorten the cable one turn. This will enable the
stationary bar to stop the control handle and protect the internal pump stop from damage. Remember, this
procedure does not apply if the Speed/Sensitivity Adjustment is in the slower setting.
So, if the mower is tracking to the left, either the left side needs to go faster (by lengthening the upper control
rod on the right) or the right side needs to go slower (by shortening the upper control rod on the left). If the
mower is tracking to the right, either the right side needs to go faster (by lengthening the upper control rod on
the left) or the left side needs to go slower (by shortening the upper control rod on the right).
The only reference point to limit the adjustment from becoming extremely off is the relative position of the
pump internal stop and the stationary bar in the faster Speed/Sensitivity setting. Therefore, if everything is
23
extremely 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 accurate. After getting the mower to track straight, readjust
the neutral adjustment, if necessary. It is normal to need to make these adjustments from time to time as the
linkage breaks in or wears.
5.10 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. 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 within 6-9 seconds each time, inspect the clutch or contact your local Wright
dealer. Under mowing load, the clutch’s life will be the greatest at the highest RPM setting.
5.11 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 6-9 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 24 psi. Higher pressures will cause the tires to have less traction which
will force you to go slower and with less safety and give you a harder ride. Front Casters are equipped with
non-pneumatic tires and do not required any air. They do not have any tread but should be replaced when
excessively worn.
6.2 Height of Cut
Before adjusting the height-of-cut be sure the mower blades are not spinning,
and rear tires have proper air pressure. Check for even tire wear. The heightof-cut can be adjusted the following ways:
• Pull the deck lift lever on the right hand side of the mower towards the rear of
the mower until it clicks once into the locked transport position. Then set the
mower blade height with the selector pin on the left hand side of the mower.
Once the proper height setting is set on the left, pull back on the deck lift
lever on the right hand side and then lower the lever towards the front of the
machine until it stops at the set height of cut.
24
6.2.1 Deck Adjustments
The mower deck can be adjusted for pitch and side-to-side lever. Pitch is the relationship between the front
of the deck and the rear of the deck in regards to height of cut. In most cases, a positive pitch (front of the
deck lower than the rear of the deck) of ¼” is the optimum setting. These two adjustments can easily be
made by using the deck lift rod assemblies attached to the front deck arms and the threaded deck hangers
located at the rear of the deck frame. These hangers are connected to the chains that hold the deck.
Adjust the rear deck hangers (by using a socket through the hole above the toe area of the platform)
to achieve a ¼” pitch. These hangers are right-han ded threads. If you raise any of these settings
above the factory setting, the deck may not raise all the way up into transport position. Be sure and
check the deck height of cut range after any adjustments are made to these hangers to ensure that
the height of cut adjustments work properly. If unable to make the adjustments needed by only
using these hangers, contact your dealer for assistance.
Lengthening the
rod will lower the
deck on the side
adjusted.

6.2.2 Deck Lift Assist Spring
To adjust deck spring tension, tighten or loosen the eye-bolt Nylock jam nut located in the front tank bracket.
If tightening for more lift assist make sure not to over tighten creating the deck to hop over rough terrain.
6.3 Spring platform Adjustment
The factory setting is both springs set at the most forward position.
The more rearward the spring position, the stiffer the platform gets.
Adjustment will be to preference of feel. The two adjustment springs
should at all times, be positioned next to each other not one forward
or back more than the other. To adjust, loosen each spring retaining
bolt from the top just enough to slide it, then tighten with impact
wrench. The nut may spin using hand wrench. NOTE, do not loosen
too much, if the nut falls off, the foot platform will have to be removed
to reinstall.
There is an extra hole for a third spring for operators heavy enough to
bottom out the duel spring stock set up.
6.4 Belt Tension Adjustment
The pump drive belt is self-adjusting, and requires no adjustment, just replacement. The blade drive belts
are self-adjusting also and require no adjustment, just replacement.
25
6.4.1 Replacing the Drive Belt
• Stop engine and remove the key and wait for all moving parts to stop.
• Remove deck covers.
• Remove cutter deck engine to blade belt from clutch.
• Raise front of unit and secure
• Remove the clutch stop
• Remove belt by using a ½” ratchet and extension to relieve belt tension.
• Reinstall in reverse order. Figure shows belt configuration.
NOTE: Ensure clutch stop is reinstalled.

6.5 How to Move the Mower if the Engine Won’t Start
Rotate both of the manual “release” valve levers on the rear 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
6.6 Hydraulic System
Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from
getting into the system. Clean off all parts before disassembly and assembly. When any of the hydraulic
parts are disconnected or removed or when the oil is changed, air must be bled from the system. If air is
entrained in the system, loss of power, excessive heat, and damage to the hydraulic pumps may occur.
First, make sure the oil level in the reservoir is correct. 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.

6.7 Oil Cooler Screen Removal and Cleaning
WARNING
Your Stander ZK is equipped with an oil cooler, the oil cooler debris screen will need to be cleaned several
times a day. Clean more often in bush hog conditions. To clean, “STOP ENGINE” lift thigh pad for access,
either wipe screen or remove screen for cleaning. To remove screen, lift and rotate spring locks to free the
screen. The screen is bowed to prevent a rattle and should be installed hump down, like a “U”. Using
compressed air or water to clean may or may not be necessary.
27
6.8 Oil Cooler Removal and Cleaning
WARNING
Clean oil cooler weekly. Clean more often in dry
conditions. To remove oil cooler for a thorough cleaning
“STOP ENGINE”, lift thigh pad for access. Loosen knob
(1) as far as necessary to slide the cooler back about 3/81/2” until clears locking tabs and then lift up and out.
(The cooler knob does not need to be removed) Watch
cooler hoses so they do not snap pump fans. The debris
screen should be removed before blowing cooler out from
the bottom. When reinstalling the cooler, make sure the
cooler hoses do not interfere with the fans and ensure the
cooler housing is secure under the four tab points of the
cooler bracket. Tighten knob securely.

6.13 Cutting Blades
WARNING
In order to maintain the best cut, it is important that the blades are well sharpened and not damaged. Bent or
cracked blades or blades with large nicks need to be replaced. Blades must be balanced after sharpening.
To change the blades:
• Stop engine, remove the key and wait for all moving parts to stop.
• Engage the parking brake
• Lift front of mower and secure in the raised position with jack stands.
• Remove the blade bolt by turning counterclockwise.
• Apply anti-seize to the blade bolt.
• Install new or re-sharpened blade, start mounting bolt by hand. (Ensure the blade spacers are
reinstalled with the same qty and location)
• Torque blade bolt to 70-80 ft/lbs / 95-108 Nm
6.14 Transporting
Use a heavy duty trailer or truck to transport the Stander ZK. Lock brake and block wheels. Securely fasten
the unit to the trailer or truck with straps, chains, cable or ropes.
6.15 Loading and Unloading
WARNING
Use extreme caution when loading and 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.
6.16 Lubrication
Grease with No. 2 general purpose lithium base or molybdenum base grease.
• Set parking brake, stop the engine
and remove the key.
• Clean grease fittings with a rag.
• Connect grease gun to fitting and
pump until grease begins to ooze
out from the bearings.
• Wipe off excess grease.
• Do not use spray lube of any kind
on choke and/or throttle cables.
• Service intervals:
First 8 hours

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 bearings and electrical
connections causing an electrical short, rust and corrosion. When washing with water, avoid spraying near
the hydro cap and do so when the unit has cooled down. Washing a hot machine can cause various
unseen system damage. If water is used for cleaning, immediately dry it with a leaf blower or low-pressure
compressed air and run with blades engaged for approximately 10 minutes. Once the wash is complete,
always lubricate and grease all applicable areas.
