ASSEMBLY OF BLADE TO TRACTOR

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.

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.

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.

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.

22. Align two front holes in Support Bracket with holes

in front of foot rest on right side of tractor frame.

Remove any bolts present in holes, but leave all

brackets in place. Attach the Support Bracket using

two 3/8" x 1-1/4" hex bolts and 3/8" Nylock nuts. If

bolts won't fit, use 3/8" x 1" thread forming bolts

without the Nylock nuts. See figure 22.

17. Move attachment lift lever all the way forward and lock

in position. See figure 28 on page 10.

18. Assemble lift arm link over channel rod and insert pivot

shaft end (from R.H. side of tractor) into hole in L.H. lift

pivot plate. Secure lift arm link to channel rod with 1/8"

(large) hairpin cotter. See figure 19.

19. Assemble a frame bracket under the right hand foot

rest of the tractor using 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. See figure 19.
