    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 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.

    Abstract: A high-efficiency cutting system for an autonomous mower provides a multiple blade tip cutting radius for a cleaner cut, and more complete mow. The system includes a spinning blade disk provided within a housing including a vertical standoff. The blade disk includes a first pair of cutting blades located between the center of the blade disk and the circumference of the blade disk, and a second pair of cutting blades located radially inward from the first pair of cutting blades. The cutting blades extend downward and away from the blade disk at an angle.

    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.
