Abstract: Some implementations can include a zero turn radius utility vehicle that is operated in a standing position by an operator using foot controls provided on the utility vehicle. Accordingly, the operator's hands are free to operate handheld equipment (e.g., a line trimmer, edger, blower, etc.) while the operator controls the utility vehicle via the foot controls. Further, the utility vehicle may have a single third wheel (and no mower deck or other deck or protrusion) extending from the front of the vehicle frame so as to minimize any protrusions to the front of the vehicle, which can permit the operator to work on the ground in front of the utility vehicle using handheld equipment without interference from a mower deck, while remaining in a standing position on the utility vehicle and being able to simultaneously control the utility vehicle (via foot controls) and perform work with handheld equipment.

Abstract: Motorized hub assemblies for use with platforms and the corresponding motorized platforms are presented. At least one of the hub assemblies can be a motor and can contain an internal motor to propel the platform when activated. In some embodiments, the motorized platform has two sets of motorized wheels or two sets or motorized treads for differential rate maneuvering. In some embodiments, different base platforms are mounted to a single set of wheels or a single tread to provide a sporty style ride. A handlebar can also be implemented for greater stability. In all cases, there is no requirement for an electronic stabilization platform.

Abstract: A stand-up grounds maintenance vehicle including a chassis, a control tower, an implement, and a cover. The chassis is supported upon a ground surface by a plurality of ground-engaging members and extends along a longitudinal axis between a front end and a rear end. The control tower is coupled to the chassis proximate the rear end. The implement is attached to the chassis and is positioned at least partially forward of the control tower. The implement includes an implement drive. The cover extends over the implement drive and is pivotally coupled to the chassis.

Abstract: A working machine has a frame, a ground engaging propulsion system, a drive arrangement for providing motive power to the ground engaging propulsion system, an operator platform pivotally connected to the frame and moveable between a deployed position for supporting an operator thereon and a stowed position; and a sensor arrangement configured to sense when an external force is applied to the operator platform when said operator platform is in the deployed position. The machine prevents movement of the ground engaging propulsion system when the sensor arrangement does not sense an external force applied to the operator platform when said operator platform is in the deployed positon.

Abstract: A control device for an autonomous lawn mower is described which receives input signals from a first and/or second hand control and determines a control signal for controlling the autonomous lawn mower. The hand controls may provide for intuitive control of the mower by a user. The control signals may be used to operate the autonomous lawn mower to perform a task such that, when later detached or otherwise decoupled, the autonomous lawn mower may perform the same or similar tasks substantially autonomously based on data (e.g., sensor signals, control signals, etc.), generated during manual operation. In some examples, the control signals may be determined to aid a user in maintaining a straight mow, proximity to a desired pattern for mowing, and/or be otherwise altered based on the presence of a user.

Abstract: The present disclosure provides a snow transport system with a frame comprising a base plate, a pair of opposed side plates mounted on opposed sides of the base plate, and a plurality of cross members extending between the side plates. A pair of convex lower track slides are mounted on lower portions of the pair of opposed side plates, and a pair of convex upper track slides are mounted on upper portions of the pair of opposed side plates. A drive wheel is mounted at an upper front portion of the frame, and an idler wheel mounted at a lower rear portion of the frame. A continuous track is wrapped around the drive wheel, the convex lower track slides, the idler wheel and the convex upper track slides. A motor assembly is mounted within the frame, and connected to the drive wheel through a transmission assembly. A push arm assembly is mounted to one side of the frame, the push arm assembly extending forwardly from the frame and having a push bar portion and user controls at a forward end thereof.

Abstract: A drive assembly for a walk-behind, powered device operably couples an engine of the powered device to a mobility assembly to provide mobility of the powered device responsive at least in part to operation of the engine. The drive assembly includes a transmission shaft and a short turning assembly. The transmission shaft selectively receives drive power operably coupled from the engine to drive a first drivable component and a second drivable component of the mobility assembly. The first and second drivable components are disposed substantially at opposite sides of the powered device. The short turning assembly is configured to cause both disengagement of drive power and activation of braking to the first drivable component while drive power is provided to the second drivable component.
