Abstract: A suspension for a tracked utility vehicle is provided. The trailing link suspension for the tracked utility vehicle has at least two trailing links. Each of said trailing links has a shock and a walking beam. The first end of the trailing link is pivotably connected to the tracked utility vehicle chassis. The second end of said trailing link is pivotably connected to the walking beam. The first end of the shock is pivotably connected to the chassis and the second end is pivotably connected to the trailing link. The walking beam has a plurality of axle mounted bogey wheels for engaging one or both of the track of said tracked utility vehicle or the track lug or guide. The shocks are independently adjustable to permit more of the tracked utility vehicle's weight to be supported at the suspension midpoint.

Abstract: A steering assembly for a lawn maintenance vehicle having a control assembly that receives a user rotational input, a transfer assembly for transferring the rotational input from the user to a pair of wheel assemblies. Each wheel assembly includes a knuckle connected to a pivot bar by way of a kingpin, wherein the kingpin is positioned within the rim of the tire operatively connected to the knuckle. The transfer assembly includes a sector gear having a leading edge that forms a rack that is meshingly engaged to a pinion gear of the transfer assembly.

Abstract: A drive sprocket for driving a track of a tracked vehicle is provided. The drive sprocket includes an interior ring, an exterior ring, and an intermediate ring situated between the interior ring and the exterior ring. The interior ring, exterior ring, and intermediate ring are oriented in a substantially spaced-apart manner, each of the rings have an outer peripheral surface. A plurality of rods is attached to the rings adjacent to the outer peripheral surface thereof. The interior, exterior, and intermediate rings have a substantially “U” or “J” shape.

Abstract: The disclosed technology relate to a device and system that include an outdoor power equipment power unit or cart configured to releasably couple a number of different interchangeable attachments or work implements to a common power unit, where some attachments include and/or require operator presence control, while other attachments do not include and/or require operator presence control. The outdoor power equipment power unit includes a power transfer coupling member operatively coupled to the drive shaft and configured to transfer rotational power to the associated attachment; and an operator presence actuation member operatively coupled to the operator presence control member, the operator presence actuation member configured to rotate in response to user actuation of the operator presence control member.

Abstract: 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 interior ring, exterior ring, and intermediate ring are oriented in a substantially spaced-apart manner, each of the rings have an outer peripheral surface. A plurality of rods is attached to the rings adjacent to the outer peripheral surface thereof. The interior, exterior, and intermediate rings have a substantially “U” or “J” shape.

Abstract: A package assembly for packaging a replacement mower blade is provided. The package assembly includes a blade hang tab removably attached to an end of a mower blade. A shrink film tube is positioned about the mower blade and blade hang tab, wherein the shrink film is heated to shrink the shrink film and secure the blade hang tab to the mower blade. In another embodiment, the package assembly includes multiple blades encased within shrink film with a blade hang tab attached to one of the blades within the shrink film.

Abstract: A speed control mechanism for controlling selective engagement of the self-propelled transmission assembly for a walk-behind lawn mower is provided. The speed control mechanism is also configured to control the relative output speed of the transmission assembly. The speed control mechanism includes a speed engagement assembly and a speed adjustment assembly, wherein the speed engagement assembly includes a pair of rotatable levers for causing the transmission assembly to actuate between a disengaged position and an engaged position and the speed adjustment assembly includes a rotatable knob for causing the relative output speed of the transmission assembly to the wheels of the lawn mower to increase or decrease.

Abstract: 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.
