Mount Backhoe to Tractor
This mounting kit is designed to provide
secure mounting and adequate operator clear-
ance for most operators 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 ideal 40-inch
clearance. For 36.5-inch radius operation, taller
operators may need to wear a hardhat for greater
comfort and safety.
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 backhoe
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 power
unit. 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 backhoe hydraulic reservoir (if
equipped) to make sure backhoe PTO driven
hydraulic system is full (approximately 6.5 to 7
US gallons). Service if necessary.
NOTE: See the BH90-X Backhoe Operator’s Manual
for hydraulic oil recommendations. Do not mix
hydraulic fluid types.
Mount Backhoe
1. Remove the backhoe seat assembly.
2. Back tractor up to backhoe and center mount
between the tractor rear tires. Position tractor so
that the hydraulic system can be connected. Shut
off tractor, set brake, remove key.
3. Attach backhoe hydraulic system.
A. Connect hydraulic hoses. See Figure 16.
OR
B. Connect hydraulic pump.
3. With the tractor PTO and transmission in neutral,
start the engine and run at low idle. Hydraulic
power is provided when the tractor is started.
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 con-
trol lever stuck in an operating position.
NOTE: You will use the backhoe hydraulics to
maneuver the backhoe brackets into position.
Use care in this procedure to avoid being trapped
between tractor and backhoe or between back-
hoe parts.
