Dozer Blade Assembly

1. Remove blade mount, hitch adapter and dozer blade from boxes; lay blade mount on flat surface; set hitch adapter aside. Ensure all parts are included in the parts bag.

2. Remove the pivot shaft from the back of dozer blade and align the pivot shaft sockets on the blade mount and dozer blade.

3. Begin feeding the pivot shaft through by hand from left to right through the pivot shaft sockets. Then, using a hammer and punch, tap the pivot shaft through the pivot shaft sockets making sure to align the roll pin holes on the left hand side. The pivot shaft should have a snug fit in the sockets with no play or looseness.
   NOTE : If needed, tap the pivot shaft back through the left pivot shaft socket approximately one inch and, using pliers rotate the pivot shaft to more closely align the roll pin holes. Tap pivot shaft back in place, and using a tapered punch inserted into roll pin holes, maneuver pivot shaft into alignment.

4. After ensuring proper alignment of the roll pin guides, use a hammer to tap roll pin into place as shown in figure 1.1.

5. Loop the extension spring through the spring mount tab in the center of the blade mount. Loop the eye bolt over the other end of the extension spring, and pull up on the extension spring so the threads of the eye bolt protrude through the eye bolt bracket as shown in figure 2.1.
   NOTE : Stretching the spring to fit through the bracket may require two hands and an assistant may be needed to install the ESNA nut.
   Place washer over the eye bolt and begin threading the ESNA nut onto eye bolt enough to hold eye bolt in place. Hold the eye bolt with pliers, and finish tightening the ESNA nut as shown in figure 2.2.
   NOTE : Eye bolt threads need to protrude through the ESNA nut by at least 2 threads as in figure 2.3. See Dozer Blade Operation section for additional notes on the extension spring.

Attaching Dozer Blade to Tractor

NOTE : Depending on the tractor, either the H10 or H19 Implement Mount Hitch will need to be installed on the tractor prior to attaching the dozer blade. See page ii to determine the correct implement mount hitch.

1. Method 1: When attaching the dozer blade to the implement hitch, slide hitch adapter onto implement hitch.

2. Method 2: Lower the hitch adapter tongue until it is just above the ground, and slowly drive forward until the tongue is fully engaged in the dozer blade receiver.

3. Once the hitch adapter tongue is fully engaged into the receiver, lock the dozer blade in place.
   H10 Instructions

4. On the H10 implement hitch, pull hitch lock lever fully forward and down to the LOCKED position (figure 3.3), and secure the quick hitch latch with the linch pin (figure 3.4). Close PTO shield.

5. On the H19 implement hitch, pull hitch lock lever fully to the rear and down to the LOCKED position (figure 3.5).

6. Adjust the H19 hitch lock clevis to properly secure the implement. To adjust the tension on the tongue latch, remove the bowtie clip from the clevis pin as shown in figure 3.6, and twist the male clevis clockwise to tighten, or counter-clockwise to loosen, as needed.

7. The hitch lock lever should travel approximately 2” at grip end after implement hitch adapter is fully seated on implement hitch tongue as shown in figure 3.7.

8. Repeat adjustment procedure after first 15 minutes of operation after installing implement to check for secure mounting (to make sure implement “socket” is fully seated on “tongue” of the hitch).

9. Check adjustment of angle stop bolts with blade in the fully angled postion in both directions (figure 4.1). Confirm foot trigger locking tang engages freely in the angle adjust slot while the stop bolt is contacting the side of the hitch adapter frame (figure 4.2). Adjust as necessary.

Removing Dozer Blade from Tractor

H10 Instructions

• Lower dozer blade until just touching the ground.
• Shut off machine and set parking brake.
• Open PTO shield and remove linch pin from the quick hitch latch.
• Pull hitch lock lever fully to rear to “UNLOCKED” position.
• Slide dozer blade off implement hitch, or reverse the tractor out of the attachment.

H19 Instructions

1. Lower dozer blade until just touching the ground.
2. Shut off machine and set parking brake.
3. On the H19 implement hitch, pull the hitch lock lever fully forward to “UNLOCKED” position.
4. Slide dozer blade off implement hitch, or reverse the tractor out of the attachment.

Dozer Blade Operation

Warning
Before operating an implement, become familiar with the location and function of all operator controls. Knowing the location, function, and operation of these controls is important for safe and efficient operation.

Lift/Lower blade: The dozer blade may be raised or lowered by operating a toggle switch located on the Forward Speed Control (FSC) lever.

• Move the switch backward to lift the blade.
• Move the switch forward to lower the blade.

Blade Angle Position

• There are five positions to which the blade can be adjusted:
  • Straight forward
  • Right/Left 15 degrees
  • Right/Left 30 degrees

Adjusting Blade Angle

• While off the ground:
  • Method 1: Use one foot to hold down the foot trigger (figure 5.2) while using your other foot to push the blade into the desired position (figure 5.3). Release the foot trigger to allow locking tang to engage into place.
  • Method 2: To swing the blade into position, hold down the foot trigger (figure 5.4) while turning the tractor using the momentum of the blade to swing the blade into the desired position and release foot trigger to allow locking tang to engage into place.
• While on the ground:
  • Hold down the foot trigger (figure 5.4) and turn the machine. While turning right, dozer blade will pivot left; while turning left, dozer blade will pivot right. Release the foot trigger to allow locking tang to engage into place.

Extension Spring / Trip Spring
The dozer blade is designed to “trip” forward when striking large rocks, tree stumps, etc. Once the blade clears the obstacle, the blade will spring back to normal operating position, eliminating shock to the operator and tractor.

• Adjust the extension spring tension by holding the eye bolt with pliers and tightening the ESNA nut (figure 5.5) to the amount of tension required for safe operation (a minimum of 2 threads should protrude through ESNA nut).

Trip Lock
Rigid use: When the operator can be absolutely certain there are no rigid obstructions on the surface (e.g. broken sidewalks, tree roots, stakes, etc.) while using the dozer blade, and the forward trip action of the blade is NOT required, move the trip lock over the stop rod.

• To engage the trip lock, compress the spring and rotate the trip lock over the stop rod (figure 6.1). Release pressure on the spring, and place lock over stop rod (figure 6.2). Be sure the trip lock seats flush on the stop rod. This procedure “locks” the blade in place and will prevent the forward trip action
  • Using the trip lock is NOT recommended when obstructions can not be seen (e.g. under snow cover).
  • Rigid blade operation should only be used with low ground speed.

Maintenance

For maintenance instructions for your tractor, please see the owner’s manual for your model. If you do not have an owner’s manual, you can download one at www.walkermowers.com. Select your model, then click on “Downloads”.
Lubricate the following oil points every 25 hours of operation with SAE 10 oil:

• Blade angle pivot (figure 7.1)
• Foot trigger pivot (figure 7.2)

Check/Adjust hitch lock tension every 8 hours of operation, or as needed. See page 5 for details.
Inspect wear strip often (approximately every 2 hours of operation). Upon reaching the maximum allowable wear (approximately 1/8” remaining as shown in figure 7.3) either lower wear strip to second row of carriage bolt holes, flip the wear strip, or replace the wear strip. DO NOT allow the wear strip to become so worn as to cause damage to the dozer blade.
