STEP 5:
(SEE FIGURE 5)
This step is for tractor brands other than Sears.
If you have a Sears tractor, skip to step 9 on page 10.

the bottom of the Frame Bracket is closest to being
6" from the ground. The height of this hole will be
referred to as distance "H" in step 6.
•
Measure the inside distance between the Frame
Brackets. This distance will be referred to as distance
"W" in step 6.
STEP 6:
(SEE FIGURE 6 AND THE ILLUSTRATIONS
ON PAGE 9)

distance
"L"
in step 5.
•
Hold the Hanger Brackets with the ends pointing up.
Stack the short Hanger Bracket on top of the long
Hanger Bracket. If distance
"H"
measured in step 5
was less than 6", hold the brackets together and fl ip
them over so that the ends point down.
•
Slide the Hanger Brackets apart so that the overall
length is slightly less than distance
"W"
measured
in step 5. Center the Hanger Brackets on top of the
Thrust Channel and attach them to the selected slots
using two 3/8" x 1-1/4" carriage bolts (G) and 3/8"
nylock nuts (K).

STEP 12:
(SEE FIGURE 12)
•
Place the rear of the Thrust Channel between the
two Rear Support Channels. Install four 3/8" x 1"
carriage bolts (H) and 3/8" nylock nuts (K) using the
most widely spaced holes that are aligned with slots.
Finger tighten only.
•
If the Rear Support Channels bump against bottom
of the tractor, reattach the rear of the channels to a
lower set of holes in the Rear Mounting Bracket. If
there is more clearance than necessary between the
Rear Support Channels and the bottom of the tractor,
reattach the rear of the channels to a higher set of
holes in the Rear Mounting Bracket.
• Spread the Hanger Brackets apart as far as possible
and center the Thrust Channel under the tractor.
•
Tighten
all bolts and nuts installed up to this point.
• Measure the height of the front plate on the Thrust
Channel. If it is not 4" to 5" above the ground, reinstall
the clevis pins in the Hanger Brackets to a higher or
lower hole position to attain the correct height.
STEP 13:
(SEE FIGURE 13)
•
Assemble the pivot support bracket to the front of the
Thrust Channel using four 3/8" x 1" carriage bolts (H)
and four 3/8" nylock nuts (K). Make sure the bracket is
straight and then
tighten.
