Abstract
A single joystick type control handle controls the chute and deflector of a snowthrower. The control handle can be moved laterally from side to side and a second linkage including a gear connection laterally rotates the chute from side to side in the same direction, i.e. movement of the control handle to the left rotates the chute to the left and vise versa. The gear connection has a mechanical advantage that increases the amount of the angular rotation of the chute, i.e. the chute rotates further than the angular movement of the control handle. The control handle can also be moved longitudinally from fore to aft and a second linkage comprising a flexible cable pivots the deflector up and down on the chute in the same direction, i.e. moving the control handle forward pivots the deflector down and vise versa. A locking mechanism is provided to hold the chute and the deflector in their adjusted positions.
