ADDING ENGINE OIL
WARNING: Never overfill the engine
crankcase. The engine may overheat
and/or damage may result if the
crankcase is below the "ADD" mark or
over the "FULL" mark on the dipstick.
For best results, fill to the "FULL" mark
on the dipstick as opposed to adding a
given quantity of oil. Always check the
level on the dipstick before adding
more oil.
Refer to the LUBRICATION TABLE in the MAINTE-
NANCE SECTION of this manual to determine the
proper type of oil to add to the crankcase for the
conditions under which the engine will be operated.
• Place the tractor on a level surface and engage
the parking brake. Stop the tractor engine and
remove the ignition key.
• Clean the area around the oil filler cap to
prevent debris from entering the crankcase.
Refer to Figure 51.
• Turn the oil filler cap counterclockwise to
unscrew from the right valve cover.
• SLOWLY pour oil into the crankcase until the
oil level reaches the "FULL" mark on the
dipstick. Refer to Figure 52.
• Insert the oil fill cap into the valve cover and
turn clockwise until fully tightened. Reinsert the
dipstick into the dipstick tube and push firmly
into the tube.
IMPORTANT: The oil fill cap and dipstick must
always be installed securely in place when the
engine is running. Severe engine damage could
result from failure to do so.
CHANGING THE ENGINE OIL AND FILTER
WARNING: Because the engine is run
prior to draining the oil, the engine may
be hot. Use caution to avoid burning
yourself on engine surfaces.
The engine oil and oil filter should be changed after
the first eight hours of operation and every 100
hours thereafter. Refer to the LUBRICATION
TABLE in the MAINTENANCE SECTION of this
manual for the quantity of oil needed, and to deter-
mine the proper type of oil to use for the conditions
under which the engine will be operated.
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 engine impurities. Use
care to avoid burns from hot oil. While the engine
oil is warm, proceed as follows:
• 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.
• Remove the dipstick and oil fill cap from the
engine. Refer to Figure 51.
• Locate the engine drain valve on the rear of the
engine (See Figure 53). Place a suitable
container below the open end of the drain valve
to collect the old oil.
• Turn the valve's hex drain cock counter-
clockwise to open the valve.
• Allow the old oil to completely drain from the
engine crankcase into the container below.
• Remove the filter by turning it counterclockwise
using an automotive type filter wrench to
loosen. See Figure 54.
