Abstract: A standing operator support system for riding equipment, such as a standing mower, includes a suspendable standing platform for supporting the load of a standing operator and a suspension assembly adjustably engageable with the standing platform to suspend the standing platform relative to a fixable platform pivot axis of the standing platform. The suspension assembly is configured to allow for a uniform suspension experience for varied operators of varied weights while maintaining the standing platform in a relatively uniform and substantially horizontal orientation relative to terrain being traversed for the varied operators of varied weights. The suspension assembly is adjustable relative to the standing platform via a single motion to adjust between operator weight settings. The suspension assembly also may be adjustable relative to the standing platform for traverse over discrete raised portions of a terrain, such as a low rock wall or a curb.

Abstract: A track drive for outdoor power equipment has a support frame with a centerline and a hub bearing attached to the support frame. A drive sprocket having a nesting interior half and exterior half is attached to the hub bearing, which enables the drive sprocket to rotate relative to the support frame. The drive sprocket is attached to an associated drive hub of a piece of outdoor power equipment. Drive sprocket teeth are spaced radially about the drive sprocket, with a first set of drive teeth attached to the interior half sprocket and located on an interior side of the support frame. A second set of drive teeth are attached to the exterior half sprocket and located on an exterior side of the support frame. The drive sprocket transmits a rotational force to an endless track to rotate the endless track and propel the outdoor power equipment.

Abstract: The present disclosure describes systems and methods for maintaining gyroscopic sensor accuracy over time and across changing environmental conditions. In certain aspects, the present disclosure provides arrangements and methods for calibrating a gyroscope while it is positioned on a robotic platform. In particular, the gyroscope may positioned on a sensor platform that is moved through a series of known or measured rotations and then the gyroscope signals are compared to reference data and the sensor's gain and offset calculated. In other aspects, the present disclosure provides arrangements and methods for utilizing measurements from multiple gyroscopes that measure the same axis of rotation.

Abstract: A spool for a trimmer head has a structure for guiding a pair of separate trimmer line pieces through a core of the spool. The spool includes separate trimmer line channels formed through the core, each channel receiving one of the trimmer line pieces. A spool cover is positionable adjacent to the spool to enclose the channels. The spool cover includes a pair of cantilever springs extending therefrom for releasably securing the trimmer line pieces within the channels.
