SETTING THE AUGER BELT TENSION

STEP 58:  (SEE FIGURE 57)
•  Pull the tensioning chain until it is extended out as far 

as the 3/32" hairpin cotter installed in the chain will 
allow. Install a 1/8" hairpin cotter through the chain to 
secure it in the extended position.

NOTE:  After pulling the chain out, check to make sure 

the belt does not rub against the keeper bolts. If the 
belt rubs, slightly loosen the bolts, move them as far 
from the pulleys as possible, and retighten.

REAR REFLECTORS

 

ATTACH REFLECTORS TO REAR FENDER

STEP 60:  (SEE FIGURE 59)
•  If your tractor is not equipped with rear reflectors, 

assemble the supplied rear reflectors to the rear 
fender. Place the reflectors as close to the bottom of 

the fender and as far apart as the shape of the fender 
will allow.

CHECKLIST

Before you operate your snow thrower, please review the 
following checklist to help ensure that you will obtain 
the best performance from your snow thrower.

1.  All assembly instructions have been completed with all 

bolts and nuts properly tightened.

2.  Check the engine belt and the auger belt. Make sure 

they are routed properly around pulleys and inside all 

belt keepers.

3.  Check discharge chute for proper rotation.

4.  Check operation of tilt control for upper chute.

5.  Verify that the lift handle will lock into and release from 

the raised transport position. (Refer to the Service and 

Adjustments section.)

6.  Check skid shoe adjustment. (Refer to the Service and 

Adjustments section.)

Operating instructions begin on page 25.

raised, and the scraper plate has approximately 3" to 

4" of ground clearance.
