SUB-FRAME & BACKHOE INSTALLATION TO TRACTOR
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 in figure 1 to be sure you have
installed mounting kit correctly. Follow all mount-
ing instructions in this manual. Do not operate
backhoe unless there is adequate clearance. Fail-
ure to check and comply with these instructions
may result in serious injury or death.
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 all hydraulic fittings and lines to be
sure they are tight and free of kinks or twists.
____ Check the tractor hydraulic reservoir to
make sure backhoe PTO driven hydraulic sys-
tem is full (approximately 5-7 US gallons). Ser-
vice if necessary.
NOTE: See the BH6500/7500 backhoe operator man-
ual for hydraulic oil recommendations. Do not mix
hydraulic fluid types.
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. Install the pump bracket over the tractor drawbar
to prevent pump rotation. Engage the pump PTO
coupler pin firmly in the tractor PTO spline
groove.
5. With the tractor PTO and transmission in neutral,
start the engine and run at low idle.
6. Smoothly engage the PTO pump to provide back-
hoe hydraulics.
NOTE: Very little engine power is required to operate
the hydraulic system in this mode. Should the engine
pull down excessively, check the plumbing hook-up
for reversed lines or a control lever stuck in an operat-
ing position.
NOTE: You will use the backhoe hydraulics to maneu-
ver the sub-frame into position. Use care in this pro-
cedure to avoid being trapped between tractor and
backhoe or between backhoe parts.
7. Raise rear of sub-frame up by lowering stabilizers
and boom section until crosstube on sub-frame is
level with rear mount channel. Keep front of sub-
frame low enough to clear tractor.
8. Drive tractor back until sub-frame crosstube
slides into rear mount channel. Shut off tractor,
set brake, remove key.
9. Fasten sub-frame in place by placing clevis pins
into channel hole secure with safety pins.
10. With the tractor engine off, relieve pressure in the
backhoe boom and stabilizers to raise sub-frame
into front hanger.
11. Install bent pin and klik pin in front hanger mount.
12. Reinstall seat.
13. Start tractor and put backhoe into transport posi-
tion (see backhoe operator’s manual).
NOTE: Install swing lock before transporting.
