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” flange nuts. See Page 16 or 18 for proper orientation.
Take the lift hoses that are already attached to the furthest forward fittings 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° fitting to all the hoses.
Install a female quick coupler onto each 90° fitting 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” flange nuts. 
Take the 318” hoses and attach each one to their designated fitting 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 clarification 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.
Refer to Page #11 for clarification on the wire harness ends.

Initial System Startup

Start the tractor and run the blade thru all the functions. If any function does not work properly, bleeding of the 

system may be required. If problem still persists, call Grouser Products.
