8. Attach cable end fitting and long spacer to right
hand hole in angle stop and channel using 1/4" x
1-1/2" hex bolt and 1/4" Nylock nut. Tighten both
1/4" Nylock nuts that secure the angle stop to the
channel. See figure 8. NOTE: Keep cable and
fitting in alignment with cable mount bracket
when tightening nuts.
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.
6. Assemble one 5/16-24 hex jam nut onto threaded
end of control cable approximately 3/4" from end.
Assemble threaded cable end through round hole
in cable mount bracket and secure with another
5/16-24 hex jam nut. See figure 7.

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.
