Utility vehicle
A utility vehicle is provided that includes first and second pairs of wheels, a controller, and a potentiometer. The first pair of wheels is propelled by an internal combustion engine. The second pair of wheels is propelled by a battery-operated motor. The motor drives a transaxle that drives the second pair of wheels. The controller controls operation of the motor. The potentiometer is configured to be manually activated to propel the utility vehicle, and is coupled to the controller to send a signal to the controller to rotate the motor. The potentiometer is also configured to activate fuel flow into the internal combustion engine.
1. A utility vehicle comprising:
a first pair of wheels;
a second pair of wheels located opposite the first pair of wheels;
a first motor that is selected from the group consisting of a first electric motor and a first internal combustion engine;
wherein the first motor selectively moves the second pair of wheels;
a pusher cart selectively attachable to the utility vehicle, wherein the pusher cart includes:
a third pair of wheels;
a second motor configured to move the third pair of wheels;
wherein the second motor is selected from the group consisting of a second electric motor and a second internal combustion engine;
a hitch assembly that attaches to the utility vehicle such that the pusher cart cannot pivot laterally relative to the utility vehicle;
wherein the hitch assembly on the pusher cart also includes a first rod that attaches to the utility vehicle at a first position and to the pusher cart at a second position;
wherein the first position at the utility vehicle is higher in a vertical plane with respect to the second position at the pusher cart so when the third pair of wheels is rotated by the second motor, at least a portion of the weight of the utility vehicle is transferred to the pusher cart; and
a controller assembly located in the utility vehicle and tethered to the pusher cart to control the operation of the pusher cart to move the utility vehicle.
2. The utility vehicle of claim 1 , wherein the hitch assembly further includes a second rod located adjacent the first rod such that the second rod attaches to the utility vehicle at a third position and to the pusher cart at a fourth position such that the third position at the utility vehicle is higher in the vertical plane with respect to the fourth position at the pusher cart.
3. The utility vehicle of claim 1 , wherein the hitch assembly further includes a third rod located higher in the vertical plane than the first rod and attaches to the utility vehicle at a fifth position and to the pusher cart at a sixth position such that the fifth position at the utility vehicle is in about the same horizontal plane as the sixth position at the pusher cart.
