Engine
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
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
(c)
Figure 39. 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
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 located in this manual for proper service intervals.

WARNING
Spark Arrestor Maintenance (If equipped)
Spark arrestor assemblies must be inspected and cleaned periodically (see the
Maintenance Schedule 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 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. Under
normal operating conditions, the oil level in the expansion reservoirs does not need
to be checked and no additional oil is needed.
Changing the Transmission Oil
Please see your authorized service dealer for transmission oil changes.
Off-Season Storage
If your tractor is not going to be operated for an extended period of time (30 days
or more), the tractor should be prepared for storage. Store the tractor in a dry
and protected location. If stored outside, cover the tractor (including the tires) to
protect it from the elements. The procedures outlined below should be performed
whenever the tractor is placed in storage.
1. Change the engine oil and filter following the instructions provided in this
manual as well as the engine manual packed with this tractor.
Never store the tractor with fuel in the tank indoors or in poorly ventilated
enclosures, where fuel fumes may reach an open flame, spark, or pilot
light as on a furnace, water heater, clothes dryer, etc.
2. If storing the tractor for 30 days or more:
a. To prevent gum deposits from forming inside the engine's carburetor
and causing possible malfunction of the engine, the fuel system
must be either completely emptied, or the gasoline must be treated
with a stabilizer to prevent deterioration.
b. Using a fuel stabilizer for storage between 30 and 90 days:
• Read the product manufacturer's instructions
and recommendations.
• Add to clean, fresh gasoline the correct amount of stabilizer
for the capacity (approximately 5 gallons) of the fuel system.
• Fill the fuel tank with treated fuel and run the engine for 2-3
minutes to get stabilized fuel into the carburetor.
• Fuel left in the fuel tank deteriorates and will cause serious
starting problems.
c. Emptying the fuel system for storage of more than 90 days:
• Prior to putting the tractor in storage, monitor fuel
consumption with the goal of running the fuel tank empty.
• Run the engine until it begins to stall. Use the choke to
keep the engine running until all fuel in the carburetor has
been exhausted.
• Referring to the engine manual, drain the fuel from the
carburetor bowl.
3. Clean the engine and the entire tractor thoroughly.
