Connecting the Upper Link

1. Connect the upper link to the holes in the blower
bracket and secure it with a clevis pin and lynch pin
(Fig. 3).

2. Rotate the adjusting link to tighten the link. Do not
overtighten to raise the back end of the blower off the
ground.
3. Tighten the locknut to secure the upper link into
position.

Adjusting the PTO Shaft
Length
Important
A long PTO shaft is supplied with the
machine to accommodate large variations in the tractor's
PTO and 3 point locations. For most tractors this shaft is
too long and must be cut to the correct length or damage
may result.
1. With the blower on a level surface, lower the blower
until the input shaft is approximately the same height as
the tractor PTO shaft. This is the shortest distance
between the two shafts.
2. Measure the distance from the lock groove of the tractor
PTO shaft to the lock groove of the blower input shaft.
Record this dimension.
3. Fully collapse the PTO shaft and measure the distance
between the lock pin collars. Record this dimension.
4. At it's shortest length, the two halves of the PTO shaft
must have at least 1-1/2 inches (37 mm) of additional
clearance to collapse (Fig. 4). If the dimension in step 2
is not at least 1-1/2 inches (37 mm) greater than the
dimension in step 3, the PTO shaft is too long; proceed
to step 5. If there is enough clearance to allow the PTO
shaft to collapse, proceed to step 10.

5. Use the following calculation to establish how much
shorter the shaft must be, when connected, to ensure a
clearance of 1-1/2 inches (37 mm):
A. Subtract the dimension recorded in step 3 from the
dimension recorded in step 2. Record this
dimension.
B. Subtract the result in step 5A from 1-1/2 inches
(37 mm). The PTO shaft must be shortened by this
amount.
6. Using a hacksaw, cut the guards and the steel tubes
shorter by the calculated length. Cut both halves of the
PTO shaft.
7. Deburr the ends of the steel tubes internally and
externally.
