WARNING
Unless specifically required, DO NOT have engine running
when servicing or making adjustments to the mower. Place
both control levers in the park position and remove ignition
switch key. Read and observe all safety warnings in front of
manual.
Repairs or maintenance requiring engine power should be
performed by trained personnel only. To prevent carbon
monoxide poisoning, be sure proper ventilation is available
when engine must be operated in an enclosed area.
Your Zero Turn Riding Mower was adjusted before it left
the factory and checked for proper operation during
pre-delivery set-up. However, break-in wear and
continued use can cause some adjustments to change.
•
Be alert for unusual noises while operating the mower.
They could be signaling a problem.
•
Visually inspect for abnormal wear or damage while
servicing and making adjustments to the mower.
Proper servicing and adjustment is the key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly down time and repair.
!
WARNING
Keep your machine clean. Remove heavy trash deposits and
clippings from the machine. Keep all moving parts, hydraulic
system, engine cooling system and exhaust system clean of
trash and clippings. Accumulation of trash and/or clippings
can cause fires, hydraulic overheating and excessive belt
wear.
Clear away heavy build-up of grease, oil and dirt.
Especially clean in the areas around oil openings, fuel
openings and air inlets. Minute dust particles are
abrasive to close-tolerance engine and hydraulic
components.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled
personnel. Consult your Land Pride service center when
assistance is needed.
Torque Requirements
Refer to “Torque Values Chart” on page 58 to determine
correct torque values when tightening hardware. See
"Additional Torque Values" at bottom of chart for
exceptions to standard torque values.
Tire Pressure
Before considering any adjustment, check tire air
pressure. Unequal tire pressure will cause mower to drift
to one side. Refer to “Tire Inflation Chart” on page 58.
Front Floating Axle

Refer to Figure 3-1:
The front axle on the ZSR Models will pivot. Simply lock
the axle in place with locking pins (#1 & #2) to keep the
