LUBRICATION AND MAINTENANCE
NOTE: More frequent engine oil and filter changes
are recommended if the tractor is operated for
extended periods of time at maximum rated power
and speed. Under such conditions, or other types of
continued severe operating conditions, the engine
oil and the engine oil filter should be changed at 70
hour intervals.
1 .With the engine off, but at normal operating
temperature, drain and discard the engine oil
by removing two drain plugs, Figure 43.
Reinstall the plugs after the oil has drained
and discard the oil.
2. Unscrew the oil filter, Figure 41, catching the
used oil in a suitable container placed below
the filter. Discard the filter.
3. Coat the gasket on the new filter with a film of
oil. Screw the filter into place until the gasket
contacts its mating surface, then turn the filter
approximately 3/4 of a turn by hand. Do not
overtighten.
4. Add new oil of the type specified, page 34.
Start the engine and check the filter for leaks
after adding the oil. Be sure the oil is at the
proper level.
