Mount Sub-Frame & Backhoe to Tractor
This mounting kit is designed to provide
secure mounting and adequate operator clear-
ance when properly installed. Check clearance
dimensions shown below to be sure you have
installed seat bracket correctly. In some cases it
may be necessary to adjust the seat to the lowest
position and/or as far forward as possible in order
to achieve the 40-inch clearance.
The only time the backhoe may be operated
from a position other than the operator seat is
during backhoe attachment and removal. Opera-
tor must:
• Read Mounting Kit Manual instructions on
attaching and removing backhoe and use
extreme care.
• Always stand between rear tire and back-
hoe stabilizer arms or along side of tractor to
avoid being trapped should the boom swing
control be accidentally activated.
Remove seat and upper support assembly
before installing or removing backhoe from trac-
tor. Failure to comply may result in equipment
failure and/or personal injury.
Hydraulic System Check List
Complete check list prior to backhoe operation.
____ Check that backhoe hydraulic pump is
secured to the tractor PTO, if equipped.
____ Check the backhoe hydraulic reservoir to
make sure backhoe PTO driven hydraulic sys-
tem is full (approximately 5 - 7 US gallons). Ser-
vice if necessary.
____ Check all hydraulic fittings and lines to be
sure they are tight and free of kinks or twists.
NOTE: See the BH6500/7500 backhoe operator man-
ual for hydraulic oil recommendations. Do not mix
hydraulic fluid types.
Mount Backhoe
1. Remove the backhoe seat assembly.
2. Place sub-frame flat on a hard level surface.
3. Back tractor over the sub-frame and center
between the tractor rear tires. Position tractor so
that the hydraulic system can be connected. Shut
off tractor, set brake, remove key.
4. Connect hydraulics.
5. Start tractor.
NOTE: You will use the backhoe hydraulics to
maneuver the sub-frame into position. Use care
in this procedure to avoid being trapped between
tractor and backhoe or between backhoe parts.
6. Raise rear of sub-frame up by lowering stabilizers
and boom section until even with channels of rear
mount OR hooks are even with 3-point lift arm
pins. Keep front of sub-frame low enough to clear
tractor.
7. Drive tractor back so that crosstube slides into
channel OR sub-frame hooks attach to 3-point lift
arm pins. Shut off tractor, set brake, remove key.
8. Fasten sub-frame in place by placing clevis pins
into channel holes and secure with safety pins
OR attach lock bars, clevis pins, and klik pins.
9. With the tractor engine off, relieve pressure in the
backhoe boom and stabilizers to raise sub-frame
into front hanger.
10. Install bent pin and klik pin in front hanger mount.
11. Start tractor and put backhoe into transport posi-
tion (see backhoe operator’s manual).
NOTE: Install swing lock before transporting.
