SHORTENING DRIVELINE
1. Move snowblower up and down to get shortest
possible distance between tractor PTO shaft and
gearbox input shaft. Leave snowblower in mini-
mum distance position. Install jack stands under
snowblower for support.
2. Separate driveline into two halves and connect
them to tractor and gearbox.
3. Place driveline halves parallel to one another to
determine how much to shorten the driveline.

4. Measure from end of upper shield to base of bell
on the lower shield (A). Add 1-1/4" to dimension
(A).

7. Repeat step 4 through 6 for other half of drive.
8. File and clean the cut ends of both drive halves.
Ensure the drive halves slide smoothly together.
Do not run tractor if proper driveline engagement can-
not be obtained through these methods.
Connect driveline to tractor PTO shaft, making sure
spring-activated locking collar slides freely and locks
driveline to PTO shaft.
MACHINE BREAK-IN
Although there are no operational restrictions on the
snowblower when used for the first time, the following
items are to be checked.

1. Check all nuts, bolts and other fasteners. Tighten
to their specified torque level.
2. Check drive chain tension. Adjust as required.
3. Check that auger, fan and spout are in good condi-
tion.
