Abstract
Abstract A snowblower is disclosed having an engine, a friction disc rotatably driven by the engine, the friction disc including a friction surface and being rotatable about a first axis, a driven disc rotatable about an axis transverse to said first axis, the driven disc including a peripheral edge engageable with the friction surface, and being drivingly connected to the snowblower wheels for driving the wheels when the driven disc is driven by the friction disc. The snowblower also includes controls for controlling driving connection of the engine and an auger and for controlling driving connection of the engine and the wheels, the controls causing engagement of the auger drive before engagement of the traction drive and disengagement of the traction drive before disengagement of the auger drive.
