Abstract

A snow thrower having a discharge chute rotation and locking device. The snow thrower includes a discharge chute rotatable about a chute axis with respect to the snow thrower housing to discharge in a selected direction snow under the influence of the auger. The snow thrower also includes a rod having a longitudinal axis non-parallel to the chute axis, the rod being rotatable about the longitudinal axis and movable axially along the longitudinal axis. The snow thrower further includes a first crank member fixed for rotation with the rod and engaging a portion of the chute to cause the chute to rotate in response to rotation of the rod. A locking member is movable into and out of engagement with the portion of the chute in response to axial movement of the rod. The chute is prevented from rotating under the influence of rotation of the rod when the locking member is moved into engagement with the portion of the chute.
