HYDRAULIC SYSTEM OIL FILTER
NOTE: Replace the hydraulic system oil filter
①
after the first 50 hours of operation, and then
following every 300 hours of operation thereafter.
The hydraulic system uses a spin-on type oil filter,
located on the RH side of the front of the
transmission, below and in front of the rear axle.
To replace the filter:
1. Place a suitable container beneath the filter,
to collect any oil that drains out during the
filter change.
NOTE: Removing the hydraulic oil filter will drain
most of hydraulic reservoir.
Remove transmission drain plug ② before
removing hydraulic filter.
2. Unscrew the used oil filter ① and discard.
3. Coat the gasket on the new filter with a thin
film of clean oil. Screw the filter into place
until the gasket contacts the sealing surface,
then tighten the filter BY HAND
approximately three-quarters of a turn. Do
NOT overtighten.
4. Start the engine and check the filter for
leaks.
5. Stop the engine and check the hydraulic
system oil level. Add oil if necessary.
HYDROSTATIC TRANSMISSION (H.S.T.)
SYSTEM OIL FILTER
NOTE: Change the H. S. T. system oil filter
②
after the first 50 hours of operation, and then
following every 300 hours of operation thereafter.
The H.S.T. system oil filter is located just below
the main platform deck in front of the driver's
seat. The filter is mounted inside the LH side of
the chassis frame, facing rearward, and can be
accessed from below the tractor. It is helpful to
remove the plastic access cover in the main
platform deck immediately in front of the driver's
seat, to provide a clear view of the filter during
changeover.
To change the H.S.T. system oil filter ② follow
the procedures found above for changing the
hydraulic system oil filter.
