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: The parking brake system for a lap bar controlled lawn maintenance vehicle includes at least an actuation assembly and a stop assembly. The actuation assembly includes a push arm and a rotatable pedal arm, and the push arm is attached to a lap bar and is rotatable between and engaged position and a disengaged position. Rotation of the push arm from the disengaged position to the engaged position causes rotation of the pedal arm, and such rotation of the pedal arm causes the stop assembly to prevent the axle for the rear wheel that is controlled by the corresponding lap bar from rotating.

Abstract: Disclosed is an alternator overvoltage protection circuit having a TRIAC and a MOSFET. The TRIAC is electrically connected to the MOSFET and the TRIAC is electrically connected to a magneto. The TRIAC is configured to ground the magneto when triggered by the MOSFET. The MOSFET is electrically connected to an alternator and configured to conduct when the alternator operates in an overvoltage condition. Also disclosed is a method of alternator overvoltage protection for a piece of outdoor power equipment, the method including providing a TRIAC and an alternator rotated by an engine having a magneto, wherein the alternator outputs a voltage when rotated by the engine. The method further includes configuring the TRIAC to ground the magneto when the alternator operates in an overvoltage condition, thereby disabling the magneto, which stops the rotation of the engine and stops the alternator from outputting voltage.

Abstract: A chainsaw (100) has a chainsaw body (101), a cutting chain (103) driven by a motor, and a guide bar mounting stud (111) extending from the chainsaw body (101). The chainsaw (100) also has an adjustably connected guide bar (102) having a track for supporting the cutting chain (103) around a periphery of the guide bar (102) and an adjustment pin (114) extending from a side face thereof. The guide bar mounting stud (111) is configured to extend through an elongated slot (112) in the guide bar (102). The chainsaw (100) also has a cam (116) received on the guide bar mounting stud (111) and having an eccentric groove facing the guide bar (102). The adjustment pin (114) is received in the eccentric groove such that rotation of the cam (116) causes the guide bar (102) to move with respect to the chainsaw body (101), thereby tensioning the cutting chain (103). The chainsaw (100) also has a clutch (118) connected to the cam (116) for allowing no more than a predetermined load to be applied to the guide bar (102) for tensioning the cutting chain (103).

Abstract: A trimmer head configured to receive fixed-length segments of trimmer line has a main housing with a cylindrically shaped side wall forming an open end with diametrically opposed trimmer line holes formed therein. The main housing is rotatable about its central axis by means of a drive shaft. The trimmer head receives an insert body in its open end that is rotated by the main housing. The insert body has an arcuate channel extending from the first line hole adjacent one side of the insert body to the second line hole adjacent the diametrically opposed side of the insert body when the insert body is in a load/unload position with respect to the main housing. In this position, there is a substantially direct guide path between the first and second line holes that allows for easy movement of the line segment along the path. The insert body is rotatable and movable axially with respect to the main housing to an operational position. When in this position, the line segment is forced to take an indirect path between the first and second trimmer line holes, thereby securing the line segment in place during use of the trimmer head.
