SERVICE AND 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 maintenance procedures and
instructions.
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 very 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. Locate the oil drain hose (a) on the side of the engine.
2. Place an appropriate oil collection container with at least a 2.5 quart (2.37
liter) capacity below the opening of the oil drain hose, to collect the used oil.
Remove the oil fill cap/dipstick (b) from the oil fill tube.
3. While holding the
free end of the oil
drain hose over the oil
collection container,
unscrew the square
head hose plug (c)
from the end of the oil
drain hose. See Figure
37. Drain the engine
oil into the collection
container.
4. After draining the oil, wipe any residual oil from the oil drain hose. Thread the
square head hose plug into the oil drain hose fitting and tighten the square
head hose plug to 16 ft.-lbs. (22 N-m).
5. Remove the oil filter (d) and drain into the collection container.
6. Replace the oil filter (d), and refill the engine with new oil as instructed in
the Engine Operator’s Manual.
Note:
Place an absorbent towel beneath the oil filter to keep oil off the clutch.
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 owner’s expense may be performed
by any engine repair establishment or individual. Warranty repairs must be
performed by an authorized dealer.
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.

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.
Hydrostatic Transmission
Your zero turn tractor is equipped with two hydrostatic pumps/transaxles. Some
models are equipped with a transmission oil expansion reservoir. Under normal
operating conditions, the oil level in the expansion reservoirs does not need to be
checked and no additional oil is needed.
Checking & Adding Transmission Oil
WARNING
Check the oil level ONLY before starting the tractor when the transmission
oil is fully cooled.
1. Clean the
reservoir cap
and the area
around the
cap to prevent
debris from
contaminating
the transmission
oil. See Figure 38.
2. Turn the
reservoir
cap counter-
clockwise to
remove, then check the oil level in the reservoir. Oil should be visible at the
bottom of the cup, but the oil level must NOT be above the “FULL COLD” line.
See Figure 38. DO NOT FILL THE RESERVOIR.
3. If necessary to add oil because of some type of leakage, use a quality 20W50
motor oil and add only enough oil to bring the level to the “FULL COLD” line.
Reinstall the cap and fully tighten.
Note:
Prior to the initial operation of the tractor, the oil level in the reservoir may
be slightly higher than the maximum due to air in the oil lines. Operation of the
tractor will eventually purge the air from the lines and the oil level will settle to the
maximum.
4. Repeat the process for the other transmission.
Changing the Transmission Oil & Filter (If Equipped)
Note:
Refer to maintenance schedule chart located in this manual for proper service
intervals.
To change the transmission oil:
1. Remove the cap from the transmission oil expansion reservoir. See Figure 38.
2. Remove the three filter guard screws (a) and the filter guard (b). Clean any
loose debris from around the filter (c). See Figure 39.
3. Place and oil drain pan with an eight quart (7.6 liter) capacity below the
filter.
4. Remove the filter.
