Hydraulic Filter (Gear & Hydrostatic Drive)
Change Interval
NOTE: Replace the hydraulic filter
after the first 50 hours of operation
and every 200 hours of operation
thereafter. Your Dealer has approved
genuine filters. Do not use other type
filters.
CHANGE THE HYDRAULIC FILTER AS FOLLOWS:
1. Put the tractor on level ground, move the range shift lever to the L
position and apply the park brake.
2. Put an oil canister under the hydraulic filter.
3. Turn the filter counterclockwise to remove. Use a filter wrench if
necessary.
4. Apply clean oil to the O-ring on the new filter.
5. Install the filter. Turn the filter until the O-ring comes in contact with the
case surface. Tighten the filter an additional 2/3 turns by hand.
IMPORTANT: DO NOT use a filter wrench to install the hydraulic filter.
When the filter is too tight, you can cause damage to the O-ring and filter.
6. Wipe around the hydraulic filter with a dry cloth.
7. Change the transmission oil. See Transmission Oil Change in this
manual.
