Abstract: A mower blade assembly attaches to a rotatable spindle and includes a mounting plate which defines a first pin aperture. The mounting plate and a retaining plate are attached to the rotatable spindle. The retaining plate defines a second pin aperture. A movable pin plate comprises a pin. A blade is selectively attachable to the mounting plate. The blade defines a retaining plate aperture and a third pin aperture. A biasing member urges the movable pin plate from a disengaged position to an engaged position. The pin is engageable with the pin apertures for mounting and retaining the cutting blade to the mounting plate. The blade is attached by moving the blade over the retaining plate aperture, urging the movable pin plate to the disengaged position, rotating the blade, and releasing the movable pin plate. Another embodiment includes a force finger.

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: Disclosed is a method for identifying lawn grass which includes capturing an image of the terrain in front of a mower, segmenting the image into neighborhoods, calculating at least two image statistics for each of the neighborhoods, generating a binary representation of each image statistic. The binary representation of each image statistic is generated by comparing the calculated image statistic values to predetermined image statistic values for grass. The method further includes weighting each of the binary representations of each image statistic, and summing corresponding neighborhoods for all image statistics. A binary threshold is applied to each of the summed neighborhoods to generate a binary map representing grass containing areas and non-grass containing areas.

Abstract: Vehicle control systems that can be used, for example, to configure a vehicle (e.g., a lawn tractor or riding lawn mower) to make low- to substantially zero-radius turns. Some of the present vehicle control systems utilize at least one steered wheel position sensor to generate a signal that indicates the actual position of the steerable structure (e.g., wheel) to which the sensor is coupled, rather than a projected or anticipated position of that steerable structure. Vehicles that include such control systems.

Abstract: An air box assembly attached to an outdoor power tool for reducing sound generated by an engine is provided. The air box assembly includes a casing formed as an upper and lower housing attached to each other to define an enclosed space. The casing includes at least one air inlet and an air outlet. At least one filter is positioned within the casing. An air guide assembly is positioned within the casing such that the flow of air to the engine passes through the air guide assembly as it travels to the engine and sound from the engine passes through the air guide assembly as it exits the air box assembly. The air guide assembly includes a plurality of fluid pathways therein, wherein the fluid pathways are in fluid communication with the air outlet of the air box assembly.
