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. While the
engine oil is warm, proceed as follows:
Note:
A length of flexible tubing is
supplied with the tractor and should be
used to drain the engine oil.
• Place the tractor on a level surface
and engage the parking brake. Stop
the tractor engine and remove the
ignition key.
• Clean around the base of the oil
filter, the oil filler cap, and the
dipstick tube to prevent debris from
entering the crankcase. See Figure
27.
• Remove the dipstick.
• Attach the flexible tubing to the
drain valve on the front of the
engine.
Place
an
container below the open end of the
tubing to collect the old oil.
• Turn the valve's hex drain cock
counterclockwise until it stops.
• Allow the old oil to completely drain
from the engine crankcase into the
container below.
• Remove the filter by turning it coun-
terclockwise using an automotive
type filter wrench to loosen.
• Close the drain valve.
• Remove the flexible tubing from the
drain valve. Clean the tubing and
store in a safe place for future use.
• Clean the drain valve.
• Apply a light coating of clean oil on
the gasket of the new oil filter.
Thread the filter on by hand until
the gasket contacts the oil filter
adapter, then tighten the filter an
additional 1/2 to 3/4 turn.
• Refill
the
quantity and type of appropriate oil.
• Check oil level and make sure that
oil filler cap, dipstick and drain valve
are in place and closed.

Changing Fuel Filter
WARNING:
the front fuel filter when
engine is hot.
The tractor is equipped with two in-line
fuel filters. One filter is located at the
engine, in the fuel line to carburetor.
The second filter is between the fuel
tank and fuel pump located beneath
the rear fender. Visually inspect the
filters periodically for a build-up of
residue inside the filter body, and for a
dirty element, which can be indicated
by discoloration. Replace the fuel
filters when dirty.
NOTE: To inspect or replace the rear
fuel filter it will be necessary to remove
the seat assembly by removing the
four torx screws securing the seat
track to the tractor frame.
