TRACTOR PREPARATION
Idler Bracket Installation
NOTICE
It may be necessary to cut off front corners of
drawbar on older tractors to clear idler bracket
push arms.
Locate idler bracket (4) up against inside gear housing
(6) and determine if any of the drawbar will need to be
removed to ensure a good fit. Cut drawbar if necessary.
Install idler bracket (4) with 3/4" hardware as shown in
Figure 14 and torque bolts to 300 lbs-ft.
NOTICE
On some older tractors, it may be necessary
to substitute 5/8" hardware for the 3/4" hardware.
The 5/8" hardware is not furnished with parts pack-
age. If your wheel housing only has two holes in
front, it will be sufficient. Frequently check that
these bolts are tight to prevent idler bracket from
moving. Torque 5/8" bolts to 175 lbs-ft.
If your tractor is equipped with a fast hitch,
move hitch as far as possible to the right to prevent
interference with belt and idlers.
