Track Lock Lever
The track lock lever is located on the right side of the

auger housing and the method of track operation. Move
the lever to the right, then forward or backward to one of
the three positions. See Figure 7.

driveways to clear snow while leaving gravel
undisturbed.

independently for continuous ground contact.
