9. Attach the backhoe to the lower lift arms of the tractor
using the pins that are attached to the pallet. Refer to
Figure 1-9.
10. Remove the two 7/8” bolts in order to free the top link.
Refer to Figure 1-9.
11. Mount the top link to the tractor. There is no correct
side up for the top link. There are four different offset
positions for the top link’s vertical and horizontal
adjustment to match backhoe frame depending on
your tractor’s 3-point.
12. Mount the top link of the backhoe to the main frame
of the backhoe. To do this, maneuver the backhoe
until you can align two holes in the backhoe frame
with a set of holes in the top link. It is important to
pick a set of holes that places the backhoe in a
vertical position in relationship to the ground with a
10” to 12” ground clearance. There are four possible
positions.
13. If you have to make adjustments, make sure that the
backhoe tilts towards the tractor rather than away. If
you cannot find a satisfactory set of holes, turn the
top link upside down and try again. In some cases it
may be necessary to drill additional holes in the top
link or to shorten the top link.

backhoe to the top link using the two 7/8” x 2-1/2”
bolts and hardware that were removed in Step 20.

WARNING!
Tractor roll bars and tractor cabs can present a danger in the
operation of a three point mounted backhoe. We do not
recommend the use of a three-point backhoe in conjunction with
either a roll bar and/or a tractor cab.
!
WARNING!
Tractors with cabs must have at least 24” minimum clearance
between the end of lower links and tractor cab. Operator must
have at least 8” clearance between his back and tractor cab.
!
WARNING!
Tractor should be equipped with a front end loader or
equivalent front-end weight for safe and stable operation.
!
CAUTION!
No warranty shall be allowed as to the attachment of the
backhoe to specific tractors. It is beyond our control that tractor
manufacturers make changes which may require minor
alterations of the BH3512.
!
CAUTION!
For tractors with a top link draft control system, make sure the
draft control is in its heavy position. It is very important to
prevent the top link from exerting pressure that may activate the
draft control system. Continued operation with the draft control
system activated can cause overheating of the hydraulic fluid
and can cause tractor hydraulic pump failure. Put the draft
control lever to the bottom of the quadrant.
!
WARNING!
You must secure the backhoe top link to the main backhoe frame
with TWO 7/8” x 2-1/2” bolts and hardware. EXTREME
DANGER exists to the operator if the procedure is not properly
followed.
