Abstract: A concrete trowel including: a frame; a handle assembly extending from the frame for controlling the concrete trowel; a plurality of rotors coupled to the frame, each of the plurality of rotors including a plurality of blades; a drive assembly mounted to the frame including a plurality of motors, each mounted to a respective rotor of the plurality of rotors, operable to provide torque to the plurality of rotors to rotate the plurality of rotors about respective rotational axes; and a steering control system mounted on the handle assembly configured to selectively adjust the torque provided to one or more of the plurality of rotors and/or a rotational direction of one or more of plurality of rotors.

Abstract: A handle for a construction tool includes a lower handle portion configured to be coupled to the construction tool, an upper handle portion coupled to the lower handle portion, a handlebar coupled to the upper handle portion and configured to be grasped by a user during operation of the construction tool, and a vibration isolating joint positioned between the handlebar and the upper handle portion. The vibration isolating joint isolates the handlebar from vibration transmitted to the upper handle portion from the construction tool. The vibration isolating joint provides a first degree of freedom to the handlebar relative to the upper handle portion and a different, second degree of freedom to the handlebar relative to the upper handle portion.

Abstract: A concrete trowel includes a frame, a drive assembly including a motor mounted on the frame and a drive hub configured to receive torque from the motor, a handle assembly extending from the frame for controlling the concrete trowel, a rotor including a plurality of blades, the rotor rotatably coupled to the drive assembly for rotating about a rotational axis, and a steering control system mounted on the handle assembly to selectively adjust an orientation of the drive hub relative to a work surface in a plurality of different directions to adjust a pressure applied by the blades against the work surface.

Abstract: A powered log splitter includes a support structure configured to support a log, a ram that is operable to engage and split the log, a hydraulic drive unit to actuate the ram, and a stand-alone motor unit to power the hydraulic drive unit. The stand-alone motor unit includes a housing, an electric motor located within the housing, and a battery pack removably coupled to the housing.

Abstract: A handle for a construction tool includes a lower handle portion configured to be coupled to the construction tool, an upper handle portion configured to be grasped by a user, a support pin disposed between the upper handle portion to the lower handle portion, and a locking mechanism configured to selectively secure the upper handle portion relative to the lower handle portion. The upper handle portion pivotable relative to the lower handle portion about the support pin. The locking mechanism includes a locking pin movable between a lock position, in which the upper handle portion is not pivotable relative to the lower handle portion, and an unlock position, in which the upper handle portion is pivotable relative to the lower handle portion, and a release handle configured to selectively move the locking pin between the lock position and the unlock position.

Abstract: A concrete trowel is disclosed and includes a frame, a drive assembly including a motor mounted on the frame and a drive hub configured to receive torque from the motor, a handle assembly extending from the frame for controlling the concrete trowel, a rotor including a plurality of blades, the rotor rotatably coupled to the drive assembly for rotating about a rotational axis, and a steering control system mounted on the handle assembly to selectively adjust an orientation of the drive hub relative to a work surface in a plurality of different directions to adjust a pressure applied by the blades against the work surface.

Abstract: A drive-over mower deck includes at least one retractable front roller which is pivotable between a lowered position extending forwardly and downwardly from a rim at a front and center of the drive-over mower deck, and a retractable position in which the front roller pivots freely between the lowered position and a retracted position when the drive-over mower deck lays flat on a ground surface.

Abstract: A synchronizing system for hydraulic four wheel steering includes double acting front and rear steering cylinders. The front and rear steering cylinders are moveable between retracted and extended positions in response to the position of a power steering valve. A synchronizing valve assembly is connected by hydraulic lines between the front and the rear steering cylinders, and includes a first directional relief valve that opens in response to hydraulic fluid pressure to synchronize both steering cylinders in a full left turn position, and a second directional relief valve that opens in response to hydraulic fluid pressure to synchronize both steering cylinders in a full right turn position.
