Abstract: A cutting assembly for a mower includes a cutting unit comprising a plurality of blades; a lift arm including a float plate, wherein the cutting unit is connected to the lift arm via a yoke and wherein a slot is provided in the float plate; a lift actuator comprising a lift pin disposed in the slot; and a control system for selectively controlling a position of the lift actuator; wherein the position of the lift actuator comprises one of a first operating position, in which the lift pin is positioned proximate a center of the slot and a second operating position, in which the lift pin is positioned between the center of the slot and an end of the slot proximate a body of the actuator.

Abstract: A walk-behind mower includes a chassis, a tractive element coupled to the chassis, a cutting element rotatably coupled to the chassis, a cutter motor coupled to the cutting element, a handle assembly extending upward from the chassis, a bail arm coupled to the handle assembly, a power switch configured to selectively prevent operation of the walk-behind mower, a cutter control configured to provide a cutter activation signal in response to a user interaction, and a controller operatively coupled to the cutter motor and the cutter control. The controller is configured to activate the cutter motor to cause rotation of the cutting element in response to the bail arm moving toward an engaged position after receiving the cutter activation signal and prevent activation of the cutter motor in response to the bail arm moving toward the engaged position without having received the cutter activation signal.

Abstract: A mower system includes a mower and at least one processing circuit. The mower includes a chassis, a tractive element coupled to the chassis, a mower deck including a housing coupled to the chassis and a cutting element rotatably coupled to the housing, a first actuator coupled to the chassis, a first sensor configured to provide first sensor data related to operation of the first actuator, a second actuator coupled to the chassis, and a second sensor configured to provide second sensor data related to operation of the second actuator. The at least one processing circuit is configured to receive the first sensor data and the second sensor data, compare the first sensor data and the second sensor data, and provide a notification indicating a failure associated with the first actuator in response to a determination that the first sensor data differs from the second sensor data.

Abstract: One embodiment is a control system for a vehicle comprising a plurality of wheels, the control system comprising a master control unit (MCU); a plurality of traction systems corresponding to the wheels; and a plurality of rolling radius offset values stored in a memory device of the MCU and each corresponding to one of the wheels. The MCU determines for each wheel a command speed based on the rolling radius offset value for the wheel in combination with a tire diameter of the wheel, a steered angle of the vehicle, a traction pedal command, and vehicle geometry information, and provides the determined command speed for the wheel to the corresponding traction system, which controls a speed of the wheel based on the determined command speed received from the MCU.
