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.

Figure 2.1 Figure 2.2 Figure 2.3

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.

Figure 3.1 Figure 3.2

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.
