摘要： A lawn vehicle having a passive roll-over protection system attached thereto is provided. The roll-over protection system includes an elongated roll-bar that extends rearwardly at an angle from the frame of the lawn vehicle. The roll-bar is a generally U-shaped tubular member in which opposing distal ends of the roll-bar are operatively connected to the frame of the lawn vehicle. The system also includes a support member that provides lateral support to the roll-bar. The support member is operatively connected to the roll-bar and extends laterally from the roll-bar to the frame of the lawn vehicle for distributing the weight and forces experienced by the roll-bar.

摘要： A three-stage snow thrower having a housing, a power supply operatively connected to said housing, a longitudinal drive shaft extending from the power supply into the housing, and a lateral drive shaft extending rotatably attached to opposing side walls of the housing and being meshingly engaged with the longitudinal drive shaft within a gear assembly. The power supply drives the longitudinal drive shaft, thereby causing the longitudinal drive shaft to rotate, and at least a portion of such rotation is transferred to the lateral drive via a gear assembly. The first stage assembly includes a plurality of augers attached to the lateral drive shaft, wherein the first stage assembly pushes loosened snow axially toward the gear assembly. The second stage assembly includes at least one auger attached to the longitudinal drive shaft, wherein the second stage assembly pushes the snow from the first stage assembly axially rearward in a transverse manner relative to the first stage assembly. The third stage assembly includes an impeller that rotates to throw the snow from the second stage assembly through a chute attached to the housing to expel the snow from the housing.

摘要： A utility vehicle includes a frame, a power source, and a plurality of steerable structures. Ground engaging members are connected to the steerable structures. An operator seating area includes a steering control and a speed control. Controllers receive input from the steering control and the speed control. Motors drive the ground engaging members at different speeds and in different directions. A controller integrates a steering input with a speed input to effect rotation of the steerable structures and effect rotation of the ground engaging members. The steering control, speed control, controllers, steerable structures, and motors are configured to work together to control the rotational speed of all of the ground engaging members based upon a steering angle input and the lateral side the ground engaging member is connected to. Other examples include braking mechanisms, adjustable track width, and a sealed tubular frame.

摘要： A multiple-stage snow thrower having a housing, a power supply operatively connected to a plurality of drive shafts for rotating a plurality of stage assemblies. Each stage assembly of the multiple-stage snow thrower is configured to move snow either axially along the axis of rotation or radially away from the axis of rotation. The first stage assembly is configured to expel snow from the housing, thereby throwing the snow away from the snow thrower. The second, third, and fourth stages assemblies are configured to push the snow toward the longitudinal centerline of the housing and then rearwardly toward the first stage assembly.
