ABSTRACT:
A snow chute assembly for use with a snowblower. The chute assembly includes a snow chute having a rotatable base to be attached to the snowblower and presenting a circumference with spaced apart notches formed therein. An arc of notches extends around the circumference from one end, through a mid-point, through a second end preferably through an arc of 180.degree.-210.degree.. A gear member as driven by a drive shaft, preferably a worm gear, engages the notches. A limit switch limits the rotation of the chute on the base, the limit switch being substantially at the mid-point of the arc notches. The limit switch will engage limit arms extending from the base. One arm being at each end of the arc of notches. A base activation member includes a drive motor for rotating the drive shaft connected to the gear member, the drive shaft rotation ceasing upon engagement of the limit switch with either limit arms.
