ATTACHING WEIGHT TRAY TO TRACTOR
Loosen the top hex bolt on each side of the tractor
frame at the rear. Assemble the slotted end of the
side braces down onto the loosened bolts. Do not
tighten yet. See figure 33.
Place the weight tray on top of the tractor hitch and
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 33.
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. Do not tighten yet. See figure 33.
Fasten the cross brace to the side braces using
two 5/16" x 1" carriage bolts, 5/16" lock washers
and 5/16" hex nuts. See figure 33. Tighten all
loose bolts at this time.
NOTE: Tire chains on extra wide tires may rub the
hex bolt. See the alternate instructions on page 17.
INSTALLING THE ATTACHMENT PIN
Lift the front of the snow blower to align the holes
in the mounting plates and the side plates. From
the left side of the tractor install the attachment pin
through the holes, securing it with the 1/8" hairpin
cotter. Refer back to figure 29 on page 15.
FIGURE 33
SETTING THE AUGER BELT TENSION
Pull the tensioning chain until the end of the spring
is pulled through the hole in the side of the Clutch/
Idler assembly. Install the 1/8" hairpin cotter
through the end of the spring, securing it on the
outside of the Clutch/Idler assembly. See figure 32.
IMPORTANT: For correct belt tension, the 1/8"
hairpin cotter must attach to the end of the spring,
not to the chain.
Hold this drawing above you while viewing the
Clutch/Idler Assembly from underneath the
tractor. Right and left in the drawing will be the
reverse of the viewer's right and left.
