Abstract: The automation mechanism has of three rubber discs, two of which are connected to two swiveling brackets. The brackets are directed by two cables and two cable levers, each one connected to each handlebar. The swivelling brackets consist of two rubber discs that make contact to the center disc at the left side of the shroud. This center disc is connected to the rotating snow auger inside the shroud, which is the driving force for this invention. When one of the rubber discs makes contact with the rotating rubber disc at the center, it rotates a drive chain that is connected to a sprocket near the discharge chute. The sprocket rotates a clutch that rotates a worm gear, and in turn, rotates the discharge chute. Once the discharge chute reaches its maximum rotating limit, the clutch disengages by slipping. The operator can move the chute either right or left by pulling on either the left or right lever on the handlebars, while operating the snow blower at the same time.

Abstract: A snow removing machine including a control unit for controlling lifting and lowering of an auger housing by an electrohydraulic cylinder.

The trailing plow wing may be pivoted or urged to its aligned position in response to the center plow being substantially urged or pivoted toward its angled position or toward a position between its center position and its angled position.

Abstract: A drive arrangement for selectively repositioning a discharge spout of an agricultural harvesting machine by rotating it about a substantially vertical axis includes a drive motor coupled to a driveline incorporating a slip clutch operable for interrupting power flow to the spout in response to the driving torque exceeding a predetermined threshold value so as to prevent damage to the spout and/or drive motor when the spout impacts or is driven against an obstacle. The overload clutch is constructed so as to resist spout movement after the clutch has interrupted the flow of power through the driveline and to automatically reestablish power flow once the cause for the overload no longer exists.

Abstract: The automation mechanism comprises of three rubber discs, two of which are connect to a swivelling bracket. The bracket is directed by two cables and two cable leavers, each one connected to each handlebar. The swivelling bracket consists of two rubber discs that makes contact to a disc at the left side of the shroud. This disc is connected to the rotating snow auger inside the shroud, which is the driving force for this invention. When one of the rubber discs makes contact with the rotating rubber disc at the centre, it rotates a drive chain that is connected to a sprocket near the discharge shoot. The sprocket rotates a clutch that rotates a worm gear, and in turn, rotates the discharge shoot. Once the discharge shoot reaches its maximum rotating limit, the clutch disengages by slipping. The operator can move the shoot either right or left by pulling on either the left or right leaver on the handlebars and while operating the snow blower at the same time.

Abstract: A snow thrower comprised of a snow chute and chute deflector includes a joystick controller that may be adjusted between first, second, third and fourth positions. Adjustment of the joystick into one of the four positions causes rotation of the chute in clockwise and counterclockwise direction or causes the deflector to pivot upward or downward respectively. Both, the chute and the deflector are actuated by electric motors.

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.

Abstract: An electrically powered snow blower discharge chute adjustment mechanism generally comprised of a meshingly engaging gearing arrangement wherein one of the gears is operably connected to a conventional electric motor (the drive gear), and the other gear is fixedly, circumferentially attached to the discharge chute. A three position toggle switch positioned at the operator's station of the snow blower is electrically connected to the motor for permitting the operator selective control of the direction of rotation of the discharge chute through power generated by the motor. Further, two notches are removed from opposite ends of the gear attached to the chute. The notches provide space in which the drive gear may rotatably idle when it is not meshingly engaged with the other gear. In addition, a spring loaded plunger is respectively positioned adjacent each cutout.

Abstract: A convertible grass cutting and snow blowing machine which is supported on wheels and displaced on a surface where grass is to be cut or snow removed by a user controlling the machine from a handlebar. An engine is connected to the rotor housing which serves as a chassis, and has a drive shaft which is coupled to a rotor to impart axial rotation to the rotor. The rotor is supported between opposed side walls of a rotor housing, and is provided with at least two cutting blades secured longitudinally and spaced apart. The blades extend at a uniform height from the central axis of the rotor. Each of the blades defines a bow-shaped curve to direct grass cuttings or snow toward a mid-length region of the rotor when the rotor is rotatably driven and further, in combination with the rotor, impart a centrifugal force to direct the grass cuttings rearward toward an exit chute or snow upward toward a snow chute.

Abstract: The rotation assembly is comprised of a frame structure having a top surface. A longitudinal slot is formed along the top surface extending therethrough. A first pulley and second pulley are rotatably mounted to the top surface of the frame such that the slot is generally therebetween. A hydraulic cylinder is fixably mounted to the frame and has a pin extending through the cylinder arm of the hydraulic cylinder and the slot. Rotatably mounted on the pin atop the frame surface is a third pulley, such that activation of the cylinder arm causes the third pulley to travel along a path defined by the slot. The frame is fixably mounted to the rear of the snowblower housing. A first and second cable is fixably attached at one end to the side of the snowblower chute. The cables are looped around the pulleys in such a manner that activation of the cylinder causes the relative length of the cables with respect to the pulleys to vary, resulting in the rotation of the snowblower chute.
