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.
LOWER LINK:
3. CATEGORY I 3-PT HITCH - Connect to backhoe and
secure using hitch pins (6) and lynch pins (10).
CATEGORY II 3 PT HITCH - Use 1-7/8 long x 1-1/8
O.D. bushings (20) hitch pins (6) and lynch pins (10).

link assembly to upper connecting point on tractor 3-
point hitch using clevis pin and lynch pin from tractor. If
required, insert bushing (8, 9 or 22) into center front
link (5) to match tractor clevis pin diameter.
CAUTION: Upper connecting point where
backhoe fastens to tractor is under high load
when backhoe stabilizers lift rear of tractor.
Check backhoe and tractor components in
this area often for signs of fatiguing, loose
hardware and wear.

mainframe to maintain 90° and 15-18 inch positions
(Figures 1 & 2). If upper link interferes with seat, move
seat bracket into forward set of holes.
