Abstract: The subject matter of this specification can be embodied in, among other things, a climate control system includes a power delivery system configured to be driven by a motor of a vehicle and having a first power output that selectively provides power based on a control signal and a second power output that provides power to the vehicle, an air conditioner configured to be at least partly powered by the first electrical output and having a compressor configured to compress a refrigerant, an evaporator configured to expand the refrigerant, a first blower configured to direct air across the evaporator, and a second blower configured to direct air across a heat exchanger, and a load management controller configured to operate the air conditioner and the first control signal based on an operator parameter and one or more vehicle parameters.

Abstract: A tractor attachment mountable on a loader boom of a tractor and a tractor attachment kit. In one embodiment, the tractor attachment is a grapple assembly, and the grapple assembly kit includes a mounting assembly, a plurality of clamping units, and a plurality of support units. The clamping units and the support units are removably mountable on the mounting assembly and may be arranged in different combinations on the mounting assembly. Such combinations may range from a single clamping unit mounted on the mounting assembly to a mixture of clamping units and support units mounted on the mounting assembly to several clamping units mounted on the mounting assembly. The clamping units may have alternative pivot points to permit jaws of the clamping unit to close at different speeds and with different forces. One or more fangs may be removably mounted on a clamping unit to enhance its grip.

Abstract: Removable cab components and a removable cab assembly for a vehicle. A durable cab assembly is provided, which generally includes a roof, a windshield and a rear panel that is removably attachable to the vehicle. In certain embodiments, the roof, windshield and rear panel are separate components, each separately removably attachable to the vehicle. In certain embodiments, each component of the cab assembly is removably attachable to the roll cage of the vehicle without comprising the integrity of the roll cage. The attachment and detachment of the cab assembly can be carried out manually, by a single person, in a short period of time, without requiring separate tools. The invention is also directed to the windshield, roof and rear panel as individual components adapted for quick attachment/detachment to a vehicle, and a method of attaching or detaching cab components or a cab assembly.

Abstract: Accessory door assembly for the normally open sides of a recreational vehicle such as a golf cart. The door assembly includes a doorframe that can be secured to the vehicle, and a preferably rigid door that is easily mountable and demountable, and is movable between an open position and a closed position. The door can be secured to the vehicle in the open position so that the passengers have the option of riding in the vehicle while the door remains open. The door is contoured to match the contour of the vehicle, so that even when the door is stored in the open position, the vehicle remains aesthetically pleasing. A hinge system is utilized that minimizes the clearance necessary to open and close the door, and provides an optional assist feature that helps urge or bias the door to the open or closed position and maintain it there.

Abstract: Method of controlling the climate in a recreational vehicle with an accessory door assembly such as for a golf cart, method of mounting a door assembly, and method of golfing.

Abstract: Jack for raising and lowering a working implement such as hydraulically driven snow blades or other utilitarian accessories. Actuation of the jack allows for proper vertical alignment of the lift assembly for engagement to a vehicle chassis. Once engaged, the jack can be actuated into an inoperative position until the lift assembly is to be removed from the chassis.

The door can be secured to the vehicle in the open position so that the passengers have the option of riding in the vehicle while the door remains open. The door is contoured to match the contour of the vehicle, so that even when the door is stored in the open position, the rear vehicle wheels remain exposed. A hinge system minimizes the clearance necessary to open and close the door, and provides an optional assist feature that helps urge or bias the door to the open or closed position and maintain it there.
