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 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 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.
