Assembling Lift Components
Now that the undercarriage is installed, some assembly of components is necessary. Follow the steps listed
below. Refer to Page 7 for the correct hardware and orientation of parts.
Remove all pins on each side of the undercarriage.
Position the lift frame between the two plates on both sides of the undercarriage.
Align the lift frame to the bottom holes of the undercarriage and attach with the proper pins and hardware.
Lift the end of the cylinders up and attach to the undercarriage with the proper pins and hardware.
Attach the top arms to the top of the undercarriage with the proper pins and hardware.
Remove the male quick attaches that are in the female quicks on the blade, angle frame, or tilt frame.
Attach the male quick attaches to the lift frame and top arms with the proper pins and hardware.
If the quick couplers and coupler mount are not already attached to the left top arm, attach the coupler
mount to the left top arm with 4 - 3/8” ange nuts. See Page 16 or 18 for proper orientation.
Take the lift hoses that are already attached to the furthest forward ttings on the left and right side of the
undercarriage and attach them to the lift cylinders.
Note: For Step #10-15, refer to Page 18-21 for further information on hose routing and hose
positions. The amount and location of the female couplers is determined by functions the blade
is set up for.
Run the remaining hoses thru the hose loop on the top arm and attach a 90° tting to all the hoses.
Install a female quick coupler onto each 90° tting from the previous step.
Install each coupler into the designated hole on the coupler mount and hold them in place with the
coupler retainer plate, 3/8” x 3/4” bolts and 3/8” ange nuts.
Take the 318” hoses and attach each one to their designated tting at the center of the undercarriage.
Route the hoses thru the hose loops on the undercarriage.
Continue to route the hoses thru the tractor. Keep away from all moving parts. Refer to Page 8 for hose
routing.
If applicable, attach the wire harness to the coupler mount on the top arm with 1/4” bolts and 1/4” nuts.
Run the other end of the wire harness up into the cab of the tractor.
Locate the fused power supply. Connect the red wire to power and the black to ground. Attach the 2-lever
plug to the wire harness or install provided switch into an open switch hole in the right overhead console
or another convenient place in the tractor. Connect the wire harness to the switch.
Pull the pin puller handle on the left side of the quick attach system towards the outside of the blade to
open the quick attach system. Refer to Page #12-13 for further clarication on the quick attach system.
Tilt the male quick attaches forward slightly.
Drive the tractor forward slowly until the top edge of the male quick attach is under the top lip of the
female quick attach already on the blade assembly.
Tilt the male quick attaches backward till the blade is off the ground and the female quick attaches are
against the front of the male quick attaches.
Shut off machine and set the parking brake.
Move the pin puller handle on the left side of the blade assembly towards the center of the blade to lock
the blade in place and use the latch to lock the handle in place. If applicable, turn up the blade stands on
the blade.
Plug the male couplers into the female couplers on the top arm. Refer to Page 20-21 for proper coupler
locations for all functions. If applicable, plug the male blade break away end of the wire harness into the
female blade break away end of the wire harness on the top arm.

Hose Routing
Note: Installer is responsible to route hoses in a practical manner. The hoses need to be
routed away from sharp corners and moving parts and need to be secure.
1. Route the hoses from the bulkhead ttings at
the middle of the undercarriage thru all the hose
loops on the undercarriage. Once at the end of the
undercarriage route the hoses up along the tractor
frame following any of the tractor’s hoses while still
staying away from any sharp corners and moving
parts.
4. After attaching the hoses, enter the rear frame and
route the hoses thru the hose loops along the inside of the
frame.
5. Exit thru the rear frame as shown in the picture. Install a
90° and a male coupler at the end of each hose. Plug each
coupler into a rear SCV. As an example, keep both lift hoses
together on one section. Refer to hydraulic schematics on
Page 27 for further information.
6. After all hoses are routed, group hoses together and secure
with zip ties. Use the heavy duty zip ties for securing the
hoses that are routed thru the tractor frame. See the picture in
Step #1 above for an example.
8. Return to Page 6 and continue the installation with Step
#16.
NOTE: These pictures show 4 sets of hydraulic
hoses. The same applies for any number of
hoses. Hoses should be routed on the left side
rst and then route the remaining hoses on the
right side of the tractor frame.
2. Route 1 and/or 2 sets of hoses on the left side
of the tractor as shown in the picture. Use a 5/16” x
1” bolt, 2- 5/16” washers, and a 5/16 nut to bolt the
2 clamps to the plate on the tractor. Use the 1-1/4”
long spacer to space out the wire harness on the
tractor. Use a 5/16” x 2” bolt, 2 - 5/16” washers and
a 5/16” nut.
3. Route 2 sets of hoses on the right side of the tractor as
shown in the picture. Use the 3/4” long spacer to space out
the hose clamps on the tractor. Use a 5/16” x 2” bolt,
2 - 5/16” washers and a 5/16” nut to attach to the tractor.
NOTE: If there are more than 2 sets of hoses to
run to the back of the tractor, continue with Step
# 3. If there is only 1 or 2 sets of hoses continue
with step #4.
7. Check the hoses when the tractor is at full oscillation and
fully turned to check for any intererence.

Electric Hydraulic Angle System Operating Instructions
If your Grouser blade was purchased with the Electric Hydraulic Angle Option, you will have the ability to
angle the blade 30 degrees left or right. To achieve these angles, the two cylinders are designed to operate
independently of each other through an electric diverter valve. To angle the blade to the left, actuate the tractor
hydraulic control lever in the cab with the diverter valve un-powered. Then fully retract. To angle the blade to
the right, apply power to the diverter valve and then actuate the tractor hydraulic control lever. Always retract
cylinders fully prior to switching functions. If a cylinder fails to retract fully, clear any possible obstruction.
CAUTION: Do not bypass the hydraulic valve and plumb each cylinder to separate valves on the
tractor.
To ensure proper use and life of equipment, it is recommended to have both cylinders closed for straight ahead
dozing and only one cylinder partially or fully extended for angled dozing as shown in the diagrams below. If
the angle system is not used correctly, damage may occur.
Please contact Grouser Products with any questions by:
Phone - 701-282-7710 or 800-747-6182; Fax - 701-282-8131
CORRECT
(Left or RIght)
INCORRECT
Angle Position Sensor Adjustment
The angle position sensor is set from the factory. If the system does not function correctly, verify the gap
between the sensor and the plate and the position of the sensor. If any adjustments are necessary, follow the
instructions below.
With cylinder retracted, verify that the proximity sensor is in the center of the plate that is on the cylinder end.
To adjust the spacing between the plate and the sensor, loosen one of the nuts and turn the other nut till the
spacing between the plate and the sensor is between 3/16” and 3/8”. Once the correct spacing is achieved,
tighten the locking nut.
