Abstract: An autonomous mobile work system (20) includes a drive wheel (34) that is connected to a frame (24) and a rotating blade assembly (36). The rotating blade assembly (36) includes a blade assembly axis of rotation (38) and is connected to the frame (24) within a housing (26). The mobile work system (20) further includes a single motor (40) operably connected to the blade assembly (36). The motor (50) includes a motor output shaft (44) and the motor output shaft (44) includes an output shaft axis of rotation (46). The mobile work system (20) still further includes a gear box (50) operably connected to the drive wheel (34) and the motor output shaft (44). The single motor (50) urges rotation of both the rotating blade assembly (36) and the drive wheel (34). The gear box (50) can include a planetary gear set (104) including a ring gear (110) defining cavities (120) at its outside diameter (124). A locking shaft (126) can rotate between an engaged position and a disengaged position with one of the cavities (120).

Abstract: A gear train locking device having a locking device is provided. The gear train locking device includes a locking shaft 126 having an outside diameter 128 and a shaft axis. The locking shaft rotates about the shaft axis. Rotation of the locking shaft selectively moves the locking shaft between an engaged position and a disengaged position. The engaged position places the outside diameter of the locking shaft into engagement with at least one gear 110 to provide physical interference between the locking shaft and the gear to change the rotational motion of at least one of the gears. Another embodiment includes a locking shaft that cooperates with a plurality of gears.
Abstract translation: 提供具有锁定装置的齿轮系锁定装置。 齿轮系锁定装置包括具有外径128和轴线的锁定轴126。 锁定轴绕轴的轴线旋转。 锁定轴的旋转选择性地将锁定轴移动在接合位置和脱离位置之间。 接合位置使锁定轴的外径与至少一个齿轮110接合，以在锁定轴和齿轮之间产生物理干扰，以改变至少一个齿轮的旋转运动。 另一实施例包括与多个齿轮配合的锁定轴。

Abstract: A drive-by-wire steering system for a power equipment device is provided. One example embodiment comprises a steering interface system, a power steering system, and a communication link connecting the steering interface system and power steering system. The power steering system can adjust steering angle of wheels of the power equipment device based on inputs received from the steering interface system. The steering interface system can receive user inputs and provide powered feedback and/or a simulated caster effect via a steering interface. Additional embodiments include power equipment devices and steering interface systems.

Abstract: A vertical tine tiller having vertically oriented tine assemblies that are configured to rotate about vertical axes is provided. The tiller includes a power source that drives a horizontally-aligned driveshaft, which can selectively drive a transmission assembly. Horizontal rotation of the driveshaft is directly transferred into vertical rotation of a pair of drive rods to which the tine assemblies are attached.
