Safety Precautions
A careful operator is the best operator. Most accidents can be avoided by observing certain precautions. To
help prevent accidents, read and take the following precautions before operating this equipment. In addition
to these precautions, please follow all safety and operational instructions of your tractor manufacturer.
The Dozer:
1. The Ag Pro Plus HD Dozer should be operated only by those who are responsible and instructed to do so.
2. Read the owner’s manual carefully before using this equipment. Lack of operating knowledge can lead to
accidents.
3. Keep the dozer maintained in reliable and satisfactory condition to ensure your safety.
4. Make sure the area is clear of people before moving any equipment.
5. Do not modify or permit anyone else to modify or alter the equipment and its components without rst
consulting Grouser Products.
Servicing the Dozer:
1. Read and follow all safety instructions provided by the tractor manufacturer.
2. Always use proper personal safety gear when performing maintenance on equipment.
3. Before servicing, relieve hydraulic pressure, stop engine and fully engage parking brake.
4. Escaping hydraulic uid under pressure can penetrate skin causing serious injury. If uid is injected into
skin, obtain medical attention immediately.
– DO NOT use your hand to check for leaks. Use a piece of cardboard or paper to search for leaks.
– Stop the engine and relieve pressure before connecting or disconnecting lines.
– Tighten all connections before starting the engine or pressurizing lines.
Storing the Dozer:
1. Thoroughly clean the dozer before storage. Use paint where necessary to prevent rust.
2. Check for worn or damaged parts. Install new parts as required.
3. Lubricate all pins and joints.

Assembling Lift Components
Install undercarriage per the tractor specic mounting instructions. Some assembly of Lift system components is
necessary. Follow the steps listed below. Refer to Page 5 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.
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 top arm with 2 - 1/2” Carriage bolts and 2 - 1/2” Nuts. See Page 20 for proper orientation.
Take the lift hoses that are already attached to the bulkhead ttings on the undercarriage and attach them to the
lift cylinders.
Note: For Step #9-15, refer to Page 20 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 on the undercarriage to 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 long hoses and attach each one to a tting at the center of the undercarriage.
Mark each hose clearly so that once the hoses are routed to the back of the tractor, it’s easy to determine what
cylinder base or rod end they are connected to.
Route the hoses thru the hose loops on the undercarriage.
Continue to route the hoses thru the tractor and plug into the rear remotes on tractor. Keep away from all moving
parts.
If applicable, attach the male blade break away end of the wire harness to the coupler mount. Hold in place with
a zip tie. Run the switch end of the wire harness up into the cab of the tractor.
Locate the keyed and fused power supply. Connect the red wire to power and the black to ground. 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.
Get the blade ready to hook up by removing the 3/4” pin (#19 on Page 7) so that the skid shoes can move freely.
The blade will lean back further for easier connection onto the male quick attaches. Store the pin in the empty
hole right behind the hole you just took the pin out of.
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.
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.
Lift the male quick attaches up 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 the lock the handle in place.
Plug the male couplers into the female couplers on the top arm. Refer to Page #20 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.
Lock the Mushroom Skid Shoe Link back in place with the 3/4” pin you moved in Step #18 above.
To disconnect the blade, see Page 6.
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.
