Maintenance
WARNING! Before performing any maintenance or
repairs, disengage PTO, move shift lever into neutral
position, set parking brake, stop engine and remove
key to prevent unintended starting.
Refer to the Engine Operator/Owner Manual for engine
maintenance instructions.
Check engine oil level before each use as instructed in the Engine
Operator/Owner Manual packed with your unit. Follow the
instructions carefully.
ChangingEngine Oil (Modelswith Briggs& Stratton Engines)
For draining oil from the engine's crankcase of select model
tractors, a plastic oil drain sleeve is packed with this Operator's
Manual. To drain the oil, proceed as follows:
1. Run the engine for a few minutes to allow the oil in the
crankcase to warm up. Warm oil will flow more freely and
carry away more of the engine sediment which may have
settled at the bottom of the crankcase. Use care to avoid
burns from hot oil.
2. Open the tractor's hood and locate the oil drain port on
the right side of the engine.
3. Unscrew the oil fill cap and remove the dipstick from the oil
fill tube.
Snap the small end ofoil drain sleeve onto the oil sump.
See Fig. 6-1.

with a capacity of no less than 64 oz.
6. Service oil filter (ifso equipped) as instructed in the separate
Engine Operator/Owner Manual packed with your unit.
Perform the above steps in the opposite order after oil has
finished draining.
5. Refill the engine with new motor oil as instructed in the
Engine Operator/Owner Manual packed with your machine.
NOTE: Refer to the Engine Operator/Owner Manual packed with
your unit for information regarding the quantity and proper
viscosity of motor oil.
ChangingEngine Oil (Modelswith KohlerEngines)
_ ARNING! If the engine has been recently run, the
engine, muffler and surrounding metal surfaces will
be hot and can cause burns to the skin. 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 few minutes to allow the oil in the
crankcase to warm up. Warm oil will flow more freely and
carry away more of the engine sediment which may have
settled at the bottom of the crankcase. Use care to avoid
burns from hot oil.
2. Open the tractor's hood and locate the oil drain port on
the right side of the engine.
3. Pop open the protective cap on the end of the oil drain
valve to expose the drain port. See Fig 6-2.
