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.

Abstract: A rear tined tiller having a guiding handle which is readily adjustable vertically and laterally and wherein adjustment of the guiding handle position may be controlled by a handle position control lever attached to the free end of the guiding handle and readily accessible to the operator. The guiding handle is also supported for pivotal movement through a 180.degree. arc about a vertical pivot axis for storage and transport of the machine. The handle position control lever is also connected to the traction drive and the tine drive mechanisms to interrupt power to both the drive wheels and the tiller tines during adjustment of the guiding handle position.

Abstract: A vertical crankshaft engine is the power source of a snowblower. Two horizontal drive belts extend from a double pulley arrangement on the engine crankshaft. One drive belt extends to the vertical input shaft of the traction gear case to power the snowblower wheels. The other belt extends to the vertical input shaft of a right angle gearbox at one axial end of the collector assembly to transmit rotary motion to the collector assembly. A horizontally pivotal idler pulley selectively tensions the belt providing the motive power for the collector assembly and a clutch assembly is associated with the traction axle assembly to selectively power the snowblower wheels.The right angle gearbox housing is made in two complementary pieces which are held together by a type of snap ring and when assembled is bolted to one end of the housing of the collector assembly.

Abstract: A discharge guide is mounted on the same base as the snowblower engine. A rotatable flange assembly surrounds an outlet tube in the collector housing and a drive engagement between the rotatable flange assembly and the discharge guide transmits rotary motion therebetween. A flexible cord extends from a control assembly in the snowblower handle along the snowblower frame to the rotatable flange assembly to afford control over turning movement of the discharge guide.

Abstract: A mower is provided having an engine, handle bar assembly, and handle height adjustment braces connected to the mobile housing of the mower through resilient shock mounts for reducing engine noise and vibration; and for isolating the operator from the engine vibrations, as well as from ground induced vibrations and shocks while at the same time utilizing certain of the shock mounts for resiliently urging the handle height adjustment braces against the handle bar assembly to aid in retaining the braces coupled to the handle bar assembly.
