SERVICE AND MAINTENANCE
Lubrication
WARNING
Before lubricating, repairing, or inspecting, always disengage PTO,
set parking brake, stop engine and remove key to prevent unintended
starting.
Using a quality lubricating oil, lubricate all lubrication points. Refer to maintenance
schedule chart located in this manual for proper service intervals.
Lubricating Front Wheels
Each of the front wheel axles and rims is equipped with a grease fitting. See Figure
36 for the location of the grease fitting on the axles and Figure 37 for the location of
the grease fitting on the rims. Lubricate with a No. 2 multi-purpose grease applied
with a grease gun per the Maintenance Schedule.
Lubricating Deck Wheels
The wheels on the deck which are spherical shaped (50” and 54” decks have 4) are
equipped with a grease fitting. Lubricate with a No. 2 multi-purpose grease applied
with a grease gun per the Maintenance Chart.
Lubricating Pivot Points & Linkage
Lubricate all the pivot points on the drive system, parking brake and lift linkage per
the Maintenance Chart.
NOTE: It is not necessary to grease the steering pinion/sector gear interface. Doing so
will allow dirt to accumulate and can affect steering performance.
Hydrostatic Transmission
The hydrostatic transmission is sealed at the factory and is maintenance-free. The
fluid level cannot be checked and the fluid cannot be changed.
Spark Arrestor Maintenance (If Equipped)
Spark arrestor assemblies must be inspected and cleaned periodically (see the service
interval chart in this manual). Visually inspect the screen for tears, broken wires or loose
welds. Replace the spark arrestor assembly if any of these conditions exist. If the screen is
in good condition, clean the screen by brushing away loose dirt or carbon particles.
Tires
Keep the tires inflated to the recommended pressures. Improper inflation will shorten
the tire service life. See the tire side wall for proper inflation pressures. Refer to
maintenance schedule chart located in this manual for proper service intervals.
Observe the following guidelines:
• Do not inflate a tire above the maximum pressure shown on the sidewall of the tire.
• Do not reinflate a tire that has been run flat or seriously under inflated. Have
it inspected and serviced by a qualified tire mechanic.

Maintenance
Engine
WARNING
Allow machine to cool in an open area for at least five minutes before
storing or refueling.
Refer to the Engine Operator’s Manual for all engine issues and questions.
Note : Maintenance, repair, or replacement of the emission control devices and
systems which are being done at owner’s expense may be performed by any engine
repair establishment or individual. Warranty repairs must be performed by an
authorized dealer.
Changing the Engine Oil
WARNING
If the tractor has been recently run, the engine, muffler and surrounding
metal surfaces will be hot and can cause burns to the skin. Let the engine
cool for at least five minutes. Exercise caution to avoid burns.
NOTE: The oil filter should be changed at every oil change interval.
To complete an oil change, proceed as follows:
1. Run the engine for a short time to warm the engine oil. The oil will flow more
freely and carry away more impurities. Use care to avoid burns from hot oil.
2. Open the tractor’s hood and locate the oil drain port on the side of the engine.
3. Place an appropriate oil collection container with at least a 2.5 quart (2.36L)
capacity below the opening of the oil drain tube, to collect the used oil.
Remove the oil fill cap/dipstick from the
oil fill tube.
4. Open the protective cap on the end of
the oil drain valve to expose the drain
port. See Figure 35.
5. Push the oil drain tube (packed with
this manual) onto the oil drain port.
Route the opposite end of the tube into
an appropriate oil collection container
with at least a 2.5 quart (2.36L) capacity
to collect the used oil.
6. The engine is equipped with a twist-and-pull drain port. Turn the oil drain
valve 1⁄4-turn counter-clockwise, then pull outward to begin draining oil.
After the oil has finished draining, push the end of the oil drain valve back in
and turn 1⁄4-turn clockwise to close the oil drain. Re-cap the end of the oil
drain valve to keep debris from entering the drain port.
7. Replace the oil filter, and refill the engine with new oil as instructed in the
engine operator’s manual.
8. Reinstall the oil fill cap/dipstick.
NOTE: Place
an absorbent towel beneath the oil filter to keep oil off the engine
pulley.
NOTE: Observe proper disposal laws and regulations for gas, oil, etc. to protect
the environment.
NOTE: Maintenance, repair, or replacement of the emission control devices
and systems which are being done at the owner's expense may be performed
by any engine repair establishment or individual. Warranty repairs must be
performed by an authorized dealer.
