Seat, always engage the brake and set the
Power Unit transmission in parking gear,
disengage the auxiliary hydraulics, stop the
engine, remove the key, and wait for all
moving parts to stop.
2. Using backhoe hydraulics, lower stabilizers until
backhoe can be connected to 3-point hitch. Bottom of
backhoe boom pivot should be 15 to 18 inches off
ground when attaching to tractor lower 3-point arms.

this area often for signs of fatiguing, loose
hardware and wear.
