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 supply by your tractor manufacturer.

The Dozer:

1. The Ag Pro Plus 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 and in good condition to ensure your safety.

4. Make sure the area around you 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 trapped hydraulic 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.

Unpacking Components

Unstrap and remove any components that are attached for shipping. If any components are missing, call

Grouser.

Caution:

• Always use caution when working around any equipment.

• Always wear safety glasses.

• Follow tractor manufacturer’s safety guidelines when installing this product.

2. If applicable, remove front weights, weight bracket, and toolbox. If a tow cable kit was purchased from Grouser,

the tow cable will be reinstalled in a later step.

1. Read all instructions prior to performing installation.

NOTE: When installing hardware, only nger tighten until you get to the torquing steps.

NOTE: A full diagram of the assembly with the full list of parts is on Page 8.

NOTE: Refer to Page 10 to see a picture of the undercarriage assembly on the tractor if further clarication

of location on the tractor is needed.

4. Position undercarriage under tractor, center on the frame of the tractor.

5. Lift the rear of the undercarriage up and set the top

plates at the rear of the undercarriage on the tractor

cross member (1). Push the undercarriage back until

the vertical push plates are rmly against the cross

member.

NOTE: Tractor frame not shown in some diagrams for clarity.

8. At the rear of the undercarriage and pivot area of

the tractor, hook the rear hose routing bracket to the

tractor frame and bolt to the rear of the undercarriage

with 1” x 3” bolts, 1” hardened washers, and 1” nuts.

The nut will t between the plates on the brackets (3).

12. Torque the front vertical 20mm bolts to 432 ft-lbs.

9. Center the bracket on the undercarriage and tractor

as close as you can. Torque the 1” bolts on the bracket

to 903 ft-lbs. There can be a gap between the bracket

and the undercarriage.

3. Remove brackets from the undercarriage to make room for installing the undercarriage on the tractor and

unscrew the 1” vertical bolts at the rear of the undercarriage.

6. Lift the front of the undercarriage up and insert

8 - 20mm x 90mm bolts with a .375” thick washer

on each bolt from the bottom through the front slots

of the undercarriage that line up with the vertical

holes on the tractor frame (2).

7. After all 8 bolts are through the tractor frame,

attach with a 3/4” hardened washer and a 20mm nut

from the top. Verify that the rear of the undercarriage

is still rmly against the cross member.

11. Torque the rear vertical 1” bolts to 500-600 ft-lbs.

10. Tighten the 1” x 2” vertical at the rear of the

undercarriage (4).

13. Attach the front upper support arms to the

undercarriage with 2 - 1” x 3-1/4” bolts, 2 - 1”

hardened at washers, and a 1” nut on the top bolt

on each side (5).

14. Attach the front upper support arms to the tractor

with a 1-1/4” x 4-1/2” bolt, a 1-1/4” at washer, and

a 1-1/4” nut on each side.

15. Install the front side tube bracket on each side

of the undercarriage. The pins on the bracket will t

into the chain down hook on the inside of the tractor

frame. Attach to the undercarriage with 2 - 3/4” x 2”

bolts, 4 - 3/4” at washers, and 2 - 3/4” lock nuts on

each side (7).

16. Torque the upper support arm 1-1/4” bolts to

1,105 ft-lbs.

17. Torque the upper support arm 1” bolts to 903

ft-lbs.

18. Torque the side tube bracket 3/4” bolts to 257

ft-lbs.

19. Attach the rear hose routing plate to the tractor

frame behind the pivot point and before the drawbar.

There will 2 bolts sticking down. Attach with a 20mm

nut on each side (8). Make sure the lip of the plate is

facing towards the front of the tractor.

20. Torque the 20mm nuts to 432 ft-lbs.

23. After rst 8 hours of use, re-torque all bolts.

24. Check all fasteners regularly to ensure proper

operation of equipment.

NOTE: If applicable, refer to Page 11 to attach the

front of the tow cable.

21. Install the grill guard to the front of the

undercarriage with 3 - 3/4” x 2-1/2” bolts, 6 - 3/4” at

washers, and 3 - 3/4” lock nuts on each side (9).

22. Torque the 3/4” bolts to 257 ft-lbs.

Hose Routing

1. Route hoses through the hose loops on the

undercarriage and through the large loop at the rear

of the undercarriage.

4. Use Zip Ties to group some hoses on the left and

right side of the hose routing plate. Strap the Zip Ties

over the top part of the routing plate that is bolted

to the tractor frame to keep the hoses towards the

outside of each side of the routing plate.

6. Strap the hoses to the drawbar with a set of

hose holding plates in 2 locations (2). Place 1 set

as close to the front of the drawbar as possible and

the other behind the axle before the hoses would

be routed upwards to be plugged in.

5. Continue to route the hoses down the top of the

drawbar to the back of the tractor where you can plug

them into the tractor SCV Ports.

9. Tighten the 1/2” nuts so the hoses are tight and

don’t move. If you have the nuts as far as they

go and can’t get the plates tight against the hoses,

use the provided 3/4” spacers and 1/2” washers

between the plates and the nuts to get everything

tight against the drawbar. Refer to drawing on

pages 8-9 for clarication.

2. Send hoses through the bracket at the pivot point

but stay on the outside of the rods that are by the

center large nut on the tractor. The hoses should be

between the rods and the inside plates of the bracket

(1).

3. Route the hoses through the hose routing plate

that was installed in Step #19 on Page 5.

7. Make sure to keep some slack in the hose

between the pivot point of the tractor and the rst

set of hose holding plates. The hoses will move

when the tractor moves and oscillates.

8. For each set of plates, use 2 - 1/2” x 5-1/2” bolts

and 2 - 1/2” lock nuts. If you have a 12-20 or 3-5

dozer blade, use 1/2” x 6” bolts instead.

10. Make sure you still have some slack in the

hoses by the pivot area so the hoses don’t get

pulled too tight when the tractor moves but don’t

make them too lose that they will get caught on any

debris. Turn the tractor and oscillate the tractor to

verify there is enough slack.

11. Plug the hoses into the open SCV’s at the back

of the tractor.

NOTE: The quantity of hoses may vary depending on blade system.

NOTE: If blade system has Dual Remote Hydraulic Angle, verify that the 35” hose is used and installed

correctly. Refer to hydraulic schematic in the Owner’s Manual & Parts Book if necessary.
