Attach Backhoe to Tractor
1. Back tractor up to backhoe and 3-point mount.
Center between the tractor rear tires. Position
tractor so that the hydraulic system can be con-
nected. Shut off tractor, set brake, and remove
key.
2. Attach hydraulic pump to tractor PTO or connect
hydraulic hoses.
3. With transmission in neutral, start tractor engine
at idle speed and engage PTO or start hydraulic
flow.
NOTE: Use the backhoe hydraulics to maneuver
the 3-point mount into position. Use care in this
procedure to avoid being trapped between tractor
and backhoe or between backhoe parts.
4. Raise backhoe with stabilizer controls and level
backhoe from side to side and front to back. Set
ground clearance between 15-1/2 to 17-1/2
inches. Measure from the center of boom pivot
pin to the ground. See Figure 6.
