Beneath the tractor, the idler arm on the bottom of
the clutch/idler assembly should be pivoted to the
left side of the tractor as shown in figure 23.

between the two idler pulleys with the "V” side of
the belt seated in the grooves of the "V" pulleys.

the attachment pin through the holes, securing it
with the 1/8" hairpin cotter. Refer back to figure 22.

tensioning chain as tight as the pre-assembled
hairpin cotter will allow. Secure the chain in this
position with a 1/8” hairpin cotter. See figure 24.

frame at the rear. Assemble the slots in the side
braces down onto the loosened bolts. Do not
tighten yet. See figure 25.

using tire chains with extra-wide tires, assemble the
side braces to the tractor frame using the alternate
instructions with figure 27 on page 14.

fasten the side braces to it using two 5/16" x 1"
carriage bolts, 5/16" lock washers and 5/16" hex
nuts.
Do not tighten yet. See figure 25.
• Fasten the weight tray to the tractor hitch using a
1/2" x 1-1/4" hex bolt, a 1/2" lock washer and a 1/2"
hex nut.
