Abstract: A motor coupling assembly for a mower cutting unit includes a coupling ring connected to the mower cutting unit. The coupling ring includes a coupling face having female ramp elements created in the coupling face. Magnets are positioned about the coupling face each including a face positioned substantially coplanar with the coupling face. A ring member connected to a motor includes a ring face having male ramp elements equal in quantity to the female ramp elements. The male ramp elements extend outwardly from the ring face and engage within the female ramp elements. The ring face is retained in contact with the coupling face by only a magnetic force of the magnets. The ring member is rotationally locked with respect to the coupling ring by complete engagement of the male ramp elements within the female ramp elements.

Abstract: An operator presence control assembly for a walk-behind greens mower includes a handle supported on a frame of the walk-behind greens mower, a ribbon switch on the outer perimeter of the handle, and a circuit including the ribbon switch. The circuit is completed by applying a threshold pressure to the ribbon switch, and a device selectively energizeable via the circuit in accordance with the threshold pressure applied to the ribbon switch. As the user of the greens mower grips the handle, the ribbon switch completes a circuit to energize a switch to engage an electromagnetic clutch.

Abstract: Systems, methods, and computer-readable media are disclosed for error-compensated counting of Hall states for motor position feedback and/or commutation. An indicated Hall state is detected by digital Hall state sensors and a duration of the Hall state is compared to a specified time period. When the duration exceeds the specified time period, the indicated Hall state is compared to one or more valid Hall states and a position counter is changed for valid states. When the indicated Hall state is invalid, the position counter is not changed. The Hall state sensors may be connected to logic means and may detect the position of a rotor of a permanent magnet motor relative to a stator. When noise induces a change in an indicated Hall state, corresponding noise-induced effects on the position counter may be may be removed through error-compensated counting.

Abstract: A governor system is provided for limiting a degree of throttle travel of a throttle as a function of rotational speed of a drive axle. The governor system includes a governor shaft rotatably supported by the drive axle and operably interconnected to internal components of the drive axle for varying a feedback torque, a governor arm fixed for rotation with the governor shaft, a throttle cable interconnected with the governor arm for applying a first pulling force to the throttle and an accelerator cable resiliently interconnected with the governor arm to apply a second pulling force to the governor arm. The second pulling force induces rotation of the governor arm for applying a torque on the governor shaft. The torque balances with the feedback torque of the governor shaft for limiting the second pulling force as a function of the rotational speed of the drive axle.

Abstract: In a system for controlling the inclination angle and rotation angle of a body, a rotary actuator is coupled to a base. A pivot actuator is coupled to an output shaft of the rotary actuator. The rotary actuator controls the angular position of the pivot actuator. A displacement member is coupled to an output shaft of the pivot actuator. The pivot actuator controls the linear position of the displacement member. A support shaft is pivotably coupled to the displacement member. A spherical bearing includes a socket that is coupled to the base and a ball that is coupled to the support shaft. In this manner, the angular position and linear position of the displacement member is translated to a corresponding rotation angle and inclination angle in the support shaft. This system provides for a continuous range of rotation of the upper body and a continuous range of inclination angles in the upper body relative to the lower base.
