Initially change hydraulic oil and oil filter after the first 50
hours of operation. Thereafter, change hydraulic oil and oil
filter every 200 hours or every 2 years whichever comes

from your nearest Land Pride dealer. The Kit contains two
filters and two magnetic plugs.

can be accessed and worked on in a safe manner.
2. Place oil pan beneath pump.
3. Remove oil filter from underside of pump with 3/8”
allen wrench and replace with new bypass filter as
quickly as possible to reduce fluid loss from case.

filter.
5. Torque bypass filter to 40-50 in-lbs.
6. Wipe off excess oil from case.
7. Optional: Replace 9/16” magnetic plug with newly
supplied 9/16” magnetic plug as quickly as possible to
reduce loss of fluid.
8. Lower mower safely to the ground.

and check oil level. Oil level should be 1 7/8” from top
of case port.
