See (Figure 25), VISCOSITY CHART,
below for the proper type of oil.
Figure 25
The oil filter is located behind the left
side panel and is mounted on the
engine. See Accessing Engine
Compartment on page 19 for details
on removing the side panels.
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.
Figure 26
• 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
24 and Figure 26.
• Unseat the plastic dust cap from the
engine oil drain valve. To prevent
loss of the cap, do not remove the
cap’s retaining ring from the drain
valve. Remove the dipstick.
• Attach the flexible tubing to the
drain valve. Place an appropriate
container below the open end of the
tubing to collect the old oil.
• To open the drain valve, push it
slightly inward and turn it
counterclockwise until it stops, then
pull it outward.
• Remove the filter by turning it
counterclockwise using an
automotive type filter wrench to
loosen.
• Allow the old oil to completely drain
from the engine crankcase into the
container below. To close the drain
valve, push it inward, turn clockwise
until it stops and then release it.
• Remove the flexible tubing from the
drain valve. Clean the tubing and
store in a safe place for future use.
• Clean the drain valve and push the
plastic dust cap onto the 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 oil filter an
additional 1/2 to 3/4 turn.
• Refill the crankcase with the
appropriate quantity and type of oil.
• Check oil level and make sure that
oil filler cap, dipstick and drain valve
are in place and closed.
Sparkplugs
WARNING: To avoid
possible injury, be sure the
engine is off and has cooled
before making any
adjustments or repairs.
Remove all dirt from around the spark
plug before removing.
