SECTION IV. MAINTENANCE
ENGINE OIL
The engine oil must be drained and replaced with new
oil after the first 5 to 8 hours of engine operation and
then after every 50 hours of operation.
To aid starting, the selection of crankcase lubricating
oils should be based on the lowest anticipated
temperatures until the next scheduled oil change.
Use high quality detergent Engine Oil meeting API
service classification SG, SH, SJ or higher.
NOTE: Synthetic oil meeting ILSAC GF-2, API service
classification SG/CF ENERGY CONSERVING or
higher is an acceptable oil at all temperatures.
For oil change intervals of 50 hours, use the following
oil viscosity chart to determine the correct oil to use in
the engine.
Regularly check the oil level of the engine crankcase to
see that it is filled to the correct level. Always keep the
oil level up to the “FULL” mark on the dipstick. When
checking the oil level, the engine should be cold, the
dipstick must be withdrawn and wiped clean, then
pushed fully into the tube before being withdrawn for a
true reading.
CHECKING THE OIL LEVEL
Before each use, the oil level of the engine crankcase
should be checked to see that it is filled to the correct
level. Close monitoring of the oil level during the first 10
hours of operation of the engine is especially
important. Before checking the oil level, clean the area
around the oil level dipstick to prevent debris from
entering the crankcase. Always keep the oil level up to
the “FULL” mark on the dipstick (See Figure 20). When
checking the oil level, the engine must be cold, the
dipstick must be withdrawn and wiped clean, then
pushed fully into the tube before being withdrawn for a
true reading.
NOTE
Check the oil level only while the engine is
stopped and the tractor is level.
Figure 20
CAUTION
The dipstick must be inserted securely in the
dipstick tube when the engine is operating.
Severe engine damage could result from failure
to do so.
ADDING OIL
CAUTION
Never overfill the engine crankcase. The engine
may overheat and/or damage may result if the
crankcase is below the “LOW” 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 for information
regarding the proper type of oil to add to the
crankcase.
1. Place the tractor on a level surface and engage the
brake pedal lock. Stop the tractor engine and
remove the ignition key.

above 40°F (4°C) will increase oil consumption.
Check the oil more when using them.
