performed by trained technicians only.
Hydraulic Filter
Refer to Figure 4-5
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
first. Filter replacement kit #356-552A may be purchased
from your nearest Land Pride dealer. The Kit contains two
filters and two magnetic plugs.
Change hydraulic oil filter as follows:
1. Raise mower so that filter and 9/16” magnetic plug
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.
4. Caution: filter is plastic, excessive torque will damage
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.
9. Remove breather assembly located on top of pump
and check oil level. Oil level should be 1 7/8” from top
of case port.
10. Replace lost oil with 20W-50 Mobil oil.
11. Reinstall breather assembly into case port
12. Wipe off excess oil. A degreaser may need to be used
to remove excess oil.
