ASSEMBLY OF BLADE TO TRACTOR

TO PREPARE TRACTOR:

A. Remove the mower or any other attachment you

may have mounted to your tractor. Mark all loose
parts and save for re-assembly. Refer to tractor
owners manual for instructions on removal of the
mower or attachment.

B. Remove and save both suspension arms, along

with the nuts and washers which fasten them to
the lift link rods. Also remove the 3/8" self-tapping
bolts from each side of the tractor frame as shown
in figure 9. On some tractors the lift link nuts

will be reused to fasten the dozer blade lift
assembly to the lift link rods.

12. Assemble a lift rod trunnion (facing in) to each lift link

rod using either a, b or c:

a. two 7/16-20 hex jam nuts (48" mower decks)
b. a 3/8-16 Nylock nut and the original lock

nut you removed earlier (models before 1995).

c. a 3/8-24 hex jam nut and the original lock nut

you removed earlier (all other models)
The correct nuts will screw on easily. Tighten nuts so
that one thread of rod extends past bottom nut.

10. Assemble a frame bracket to the outside of the

tractor frame under the left foot rest. Use two 3/8"
x 1-1/4" hex bolts, two 3/8" lock washers and four
short spacers. Use two spacers on each bolt,
between the frame bracket and the tractor frame.
Use only one spacer on the rear bolt if it goes
through a sway bar bracket. See figure 15.

11. Assemble the lift pivot plate to the inside of the
frame bracket using two 3/8" x 3/4" clevis pins and
two small hairpin cotters. See figure 15.

rest of the tractor using two 3/8" x 1-1/4" hex bolts, two

spacers on each bolt, between the frame bracket
and the tractor frame. See figure 19.
