  • Patent number: 6502335
    Abstract: A self-propelled power implement having a friction drive system to transmit rotation from the engine to the wheels. The friction drive system includes an output disc and a friction disc. The output disc rotates in response to rotation from the engine's output shaft. The friction disc is coupled to the implement's wheels, and contacts the output disc and rotates in response to rotation of the output disc. The location on the output disc that the friction disc contacts determines the rotation speed of the friction disc. A flexible member is interconnected to the friction disc and a controller, and movement of the controller causes the flexible member to actuate the friction disc radially in relation to the output disc. The flexible member adjusts the location on the output disc that the friction disc contacts, and thereby adjusts the rotation speed of the friction disc and the wheels.

  • Publication number: 20020178622
    Abstract: A snow removal apparatus having a housing with first and second chambers that are in communication with each other. A rear wall and a pair of end plates form the first chamber. Each end plate has a leading edge that is positioned in an offset manner by a transition member, and each transition member is configured to act in a wedge-like manner to split sections of hard packed snow from a larger mass of snow. An auger is positioned within the first chamber and configured so that it is able to move snow towards the second chamber in a controlled manner. The auger includes at least one feeder paddle that is configured to break-up and distribute compacted snow before it enters the second chamber. An impeller is positioned in the second chamber so that its blades project into a portion of the first chamber where they are able to engage snow that is extruded past the auger ends. The blades of the impeller include sidewalls, which also break-up and distribute compacted snow before it enters the second chamber.

  • Publication number: 20020166266
    Abstract: An excavating apparatus having a rotating cutting head for precision removal of soil, for site preparation prior to construction projects where level grade is required. The powered cutting head is mounted on a longitudinal frame, with travel of the cutting head guided along the length of the frame. Adjustable positioning is provided to maintain position of the cutting head longitudinally along the frame. The frame is pivotally anchored to the ground at one end and is supported by wheels at the other end. Wheels are positioned to facilitate rotation of the frame and cutting head around the anchoring pivot, which is located at the center of the area to be excavated. The elevation of the frame is adjustable to selectively raise and lower the depth of the cutting head. The apparatus is easily transported and has the ability to perform precision excavating operations in confined areas.

  • Patent number: 6470602
    Abstract: An improved single-stage snow thrower including a wheeled frame assembly for supporting the snow thrower upon a ground surface and a driven impeller capable of being placed in ground contact to forwardly propel the snow thrower across the ground surface. A handle assembly including a user interface is further provided to permit the operator to selectively control the normal force associated with the driven impeller, and thus selectively control the propulsive drive force of the snow thrower. A bail control assembly may be provided upon the handle to permit the operator to selectively control a downward movement of the impeller to selectively control the degree of impeller ground contact.

  • Publication number: 20020152646
    Abstract: A snow removing machine having an electromagnetic clutch mounted to an output shaft of an engine, and a drive pulley. The electromagnetic clutch is mounted to a proximal end of the output shaft to be remotely separate from the engine. As a result, heat generated in the engine during operation thereof is not directly transferred to the electromagnet clutch whose magnetic force generated during operation is not deteriorated. The drive pulley is mounted to the output shaft at an area closer to the engine. The drive pulley has a lower weight than the electromagnet clutch, thereby mitigating load to be exerted to a part which supports the output shaft.

  • Patent number: 6449800
    Abstract: A blower head, comprising a frame, a brush rotatably supported by the frame, a sweeper drive adapted for rotating said brush to sweep a surface, and a blower unit adapted for removing swept-up particles away from the surface. The frame includes a mouth portion and a throat portion. The brush is rotatably supported by the frame within the mouth portion. The sweeper drive rotates the brush to sweep particles such as snow or ice on a surface toward the frame. The mouth portion and the throat portion are constructed and arranged to funnel swept-up particles from the mouth portion and into the throat portion and the blower unit positioned therein. The blower head further includes an exit chute. The blower unit creates a pressure differential between the mouth portion and the exit chute sufficient to draw the swept-up particles from the mouth portion and into the throat portion, and to blow the swept-up particles out through the exit chute.

  • Publication number: 20020095824
    Abstract: A snow blower augers snow scrapped from a path to a fan. The fan is co-axial with the auger at one end of an auger housing. A fan shaft extends through an auger tube. The fan shaft is supported on one end by a fan housing bearing attached to the housing and at the other end by a bearing in the auger tube. The auger is supported at one end by a drive housing bearing attached to the housing and at the other end by a bearing on the fan shaft. This arrangement makes it possible to have an open passage for the snow to move from the auger to the fan.

  • Publication number: 20020007573
    Abstract: A chute structure for a snow removing machine includes first and second chutes connected through a hinge to each other. The hinge includes first and second hinge plates connected together by means of a connecting pin. The first hinge plate has a tubular portion through which the connecting pin extends. The length of the tubular portion is substantially equal to the width of the first chute. The second hinge plate has first and second plates. The first plate has an opening formed therein. The opening of the first plate is aligned with an entrance of the tubular portion. The second plate has an opening formed therein. The opening of the second plate is aligned with an exit of the tubular portion. The second hinge plate has a cover portion extending between the first plate and the second plate. The cover portion is integral with the first and second plates. The cover portion covers the tubular portion. Provision of the cover portion prevents snow from being discharged from around the hinge.
