Continuous Tracks
The snow blower is equipped with an auto-
tensioner on both the left and right sides.
The system is designed to maintain constant
tension on both tracks. However, if the snow
blower fails to propel itself because the track
wheel is "jumping" drive lugs, the tracks are
too loose and are in need of adjustment. See
an authorized Service Dealer to have the tracks
properly adjusted. See Figure 4-13.
