INTRODUCTION
The Wallenstein backhoe is designed to work with a wide variety of tractors. Some tractors have the
required horsepower to operate a backhoe but do not have the structural strength to handle the stresses
a backhoe will place on the tractor frame. To solve that problem a backhoe subframe has developed by
Wallenstein to strengthen and distribute the stress more evenly along the entire frame.
There are many varieties of tractors in existence and so each sub frame is specific to a tractor model. The
illustrations shown in this manual will vary from what your specific sub frame looks like, but the mounting
procedure is the same for all.
Record your tractor model, serial number and sub frame model number here. Keep this instruction sheet for your records.

ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Working with and around heavy equipment is inherently dangerous, be aware of bystanders, your surroundings and what to do in case of emergency. Understand new your equipment and how to install and operate it safely. Read through and understand these instructions before attempting installation, please contact us if you have any questions.
Preparation:
Tractor should be lined up with the sub frame behind the tractor.
•
Have the sub frame resting on 2x4's or blocking on the ground in behind the tractor. Blocking should
match the width if the sub frame (to clear tractor tires).
•
Backhoe should be assembled but still on the shipping skid, lined up behind the sub frame.
•
The tractor must have a front bucket loader installed before installing the subframe and backhoe. The
front loader is required to offset the weight of the backhoe, as well as provide the stability required to
operate the backhoe safely.
Ensure the sub frame, backhoe, tractor and the area around them are clean and free of debris,
resting on dry level ground. Ensure the tractor is shut off, brake applied and key removed and pocketed.
OPERATOR ORIENTATION - The directions left, right, front and rear, as mentioned throughout this
manual, are determined when sitting in the tractor driver's seat and facing in the direction of travel.

Installation Instructions:
1. Remove the lower link arms of the 3 point hitch (3PH) , and set aside in a safe place.
2. Install the sub frame adaptor plates included with your sub frame kit. The adaptor plates should fit
between the loader attach points and the attach points on the tractor gear case.

3. Next install the sub frame to the backhoe,
•
find the 8 nuts and bolts included with the
sub frame kit,
•
align the sub frame up to the mounting holes
on the backhoe
•
cut the tie wraps and unclip the safety
catches (some models) on the backhoe
stabilizer arms
•
push the stabilizer control forward to release
the stabilizer arms, and manually push them
down.
•
install the bolts through the sub frame into
the backhoe, reach inside main base frame
and install and tighten the nuts.
•
remove the link pins from the sub frame
and set them beside the sub frame hanger
brackets.
Assembly
4. Start up the tractor and carefully back over the
sub frame, get close enough to the backhoe to
hook up the hydraulics. If possible keep the 3PH
pins in front of the pin brackets on the sub frame.
5. With caution, lower the boom till it contacts the
ground, then lower the stabilizers enough to
remove the blocking and skids.
Lower stabilizers and boom
When operating the boom and stabilizers,
ensure the area is clear of bystanders and
operator is safely positioned.
6. Manipulate the stabilizer arms (up or down) to
line up the pin brackets to the 3PH pins on the
tractor.
7. Carefully back the tractor till the pins engage the
pin brackets
8. Stop the tractor and set tractor brakes, slowly lift
the stabilizers then the boom, the sub frame and
backhoe are now mounted on the 3PH pins.

9. The hanger brackets on the sub frame should
be aligned with the adaptor plates on the tractor,
adjust the sub frame till the pin holes on the
adaptors and brackets align.
10. Install the sub frame link pins into the pin holes
and secure with latch pins.
11. Install a top link to the backhoe top
link attach point.

Before operating the backhoe,
•
Check that the 3PH pins and adaptor plates are securely and correctly attached to the sub frame.
•
Ensure that all fasteners are correctly torqued according to the torque specification chart.
•
Inspect and test all hydraulic connections.
•
Thoroughly read the manual and understand the safe operation and features of the backhoe.
CHECKING BOLT TORQUE
The tables shown below give correct torque values for various bolts and capscrews. Tighten all bolts to
the torques specified in chart unless otherwise noted. Check tightness of bolts periodically, using bolt
torque chart as a guide. Replace hardware with the same strength bolt.
Torque figures indicated are valid for non-greased or non-oiled threads and heads unless otherwise specified. Therefore, do not grease or oil bolts or capscrews unless otherwise specified in this manual. When
using locking elements, increase torque values by 5%.
* Torque value for bolts and capscrews are identified by their head markings.
