A bi-directional overrunning clutch for transmitting torque to drive axle halves includes a clutch housing that attaches to an input gear, and hubs that attach to the axle halves. A pair of roll cages located within the housing adjacent to the hubs have rollers. The rollers wedge between the hubs and first tapered portions on the clutch housing when the roll cage is rotated forward relative to the housing, and between the hubs and second tapered portions on the clutch housing when the roll cage is rotated in the opposite direction. Springs hold the rollers engaged with recesses in the hubs, but let the rollers lift to permit relative rotation of the hubs and roll cages. Relative rotation between the roll cages is limited: when one roll cage is wedged, the other can move only as far as a free position midway between the first and second tapered portions.

A motorized wheelbarrow including a motor and a drive pulley that rotates when the motor is operating. The motorized wheelbarrow also includes wheels and a drive train assembly for transmitting power from the motor to the wheels. The motorized wheelbarrow also includes a clutch assembly movable between a connected condition, in which the motor and the drive train assembly are connected by the clutch assembly, and a disconnected condition, in which the motor and the drive train assembly are not connected with each other, and a brake assembly movable between an engaged condition, in which the brake assembly resists rotation of the wheels, and a disengaged condition, in which the brake assembly does not resist rotation of the wheels. Both of the clutch assembly and the brake assembly are controlled by a single control assembly so that the clutch assembly and the brake assembly are mutually functionally exclusive.

Control of a self-powered floor preparation machine is provided by an ergonomic controller having a guarded control stick which has various characteristics, including its pitch, roll, yaw and height, that may all be adjusted.

This motor-integrated transmission device is provided with: a motor provided with an output shaft; a gear train; and a case. A breather part is provided which allows communication between an internal space of the motor-integrated transmission device and the outside. A case internal space and a motor internal space communicate with each other through a connection flow path provided in a different place to an insertion part of the case. The case internal space and the motor internal space communicate with the breather part.

A total task vehicle (TTV) may operate indoors to move a variety of different types of materials and accomplish a variety of different types of tasks, using tools and accessories powered by/connected to the TTV. One or more high power density (HD) battery packs may provide both 240V DC to 380V DC and 120V AC power to propel the TTV and also to function as a generator for tools and accessories attached to the TTV. A high torque/high speed convertible drive system may allow the TTV to operate in a ride-on mode, a walk-behind mode, providing for flexibility and adaptability in use of the TTV.

A walk-behind tractor has an increased ground clearance to define a plant receiving space that has a greater height than a conventional walk-behind tractor having a straight axle. The walk-behind tractor has trailing drop arms from a frame that carry wheel axles that result in an elevated height of a driveshaft. The elevated driveshaft increases the ground clearance for taller plants to pass therebeneath during operation of the walk-behind tractor which would otherwise be too tall to pass below a conventional straight axle walk-behind tractor.

A vehicle includes a frame, an electric motor coupled to the frame and configured to selectively receive power from at least one battery pack and operable in a first operation mode and a second operation mode that is different from the first operation mode. A wheel assembly is coupled to the frame and driven by the motor. A control device is operable by a user to control operation of the vehicle. The control device is moveable between a first position relative to the frame corresponding to a riding configuration in which a user is able to operate the control device while seated on a seat on the frame, and a second position relative to the frame corresponding to a walking configuration in which a user is able to operate the control device while walking adjacent the vehicle. Movement of the control device from the second position to the first position triggers conversion from operation of the motor in the second operation mode to operation of the motor in the first operation mode. Movement of the control device from the first position to the second position triggers conversion from operation of the motor in the first operation mode to operation of the motor in the second operation mode.

A motorized wheel is connected to a single boom pivotally connected to a body having front wheels. The body carries a power supply for the motorized wheel in the form of batteries and a generator. A work piece is removably carried on the body by extending across horizontal supports or in a tray having pivot extrusions slideably received on attachment brackets while support extrusions abut with the horizontal supports. The body includes first and second frames including first, second and third legs extending at obtuse angles from each other and a handle extending between the third legs. The body further includes support components holding the first and second frames in a spaced, parallel relation and supporting the batteries and the generator. A sulky is slideably connected to the single boom and upon which a worker stands.
