A versatile mobile utility cart or vehicle using either tracks, wheels or both for suspension and steering with propulsion coming from but not limited to an internal combustion engine or an electric motor. The vehicle is meant to be a utility workhorse with the ability to load and unload itself as well as drag or carry materials. The vehicle can be configured in many ways to do many tasks with the main feature being labor savings. One of the unique features of the vehicle is a loading system called a fork and foot system. For transport the forks and feet system can be raised or detached individually or as a system, this is beneficial when unloading. The foot may remain attached and used for stability. Detaching the fork and foot system as a system allows the vehicle to be used for other tasks including but not limited to: a dump vehicle; a skidder; a reel carrier; a fork lift/carrier; and a prime mover or base for brush chippers, stump cutters, tree spades and more.

A utility vehicle as set forth in claim 1 wherein said propulsion system includes a drive wheel rotatably supported on said vehicle frame, a take up wheel rotatably supported on said vehicle frame and an endless belt disposed over said drive wheel and said take up wheel whereby rotation of said drive wheel causes movement of said endless belt to propel the utility vehicle. 5. A utility vehicle comprising: a vehicle frame, including a bed; a propulsion system, said propulsion system attached to said vehicle frame for moving said vehicle frame in response to an input from a control mechanism; a loading apparatus, said loading apparatus mounted on said vehicle frame, said loading apparatus including a foot assembly and a fork assembly, said foot assembly movable to a working position wherein a portion of said foot assembly contacts the ground; said fork assembly operative to move between a first, lowered position and a second, raised position when said foot assembly is in said working position wherein as said fork assembly moves between said first, lowered position and said second, raised position, said fork assembly lifts a workpiece located on said fork assembly and deposits the workpiece on the bed; said fork assembly includes first and second fork members, each of said fork members attached to said foot assembly; a cross member extending between said first and second fork members and connecting said first and second fork members to one another; and a power cylinder, said power cylinder directly engaging and directly extending between said foot assembly and said fork assembly, said power cylinder operative to move said fork assembly independent of said foot assembly. 6. A utility vehicle comprising: a vehicle frame, said vehicle frame having a front end and a rear end; a platform formed on an upper surface of said vehicle frame; a power source located on said vehicle frame near said rear end; a propulsion system attached to said vehicle frame for moving said vehicle frame in response to an input from a control mechanism, said propulsion system connected to and receiving power from said power source; a loading apparatus, said loading apparatus including a foot assembly and a fork assembly, said foot assembly connected to said vehicle frame and including first and second foot members, each of said foot members including a base portion and a leg portion, said fork assembly including first and second fork members each of said fork members including a lifting portion, a leg portion and an arm portion, said fork assembly mounted to said foot assembly for movement independent of said foot assembly wherein in at least one position said lifting portion of said fork assembly is positioned adjacent said base portion of said foot assembly; and a power cylinder connected directly between said fork assembly and said foot assembly, said power cylinder operative to move said fork assembly independent of said foot assembly. 7. A utility vehicle as set forth in claim 6 wherein said control mechanism includes a remote unit, said remote unit receiving input from an operator and transferring said input to said control mechanism for controlling said propulsion system, foot assembly and fork assembly. 8. A utility vehicle as set forth in claim 6 wherein said propulsion system includes a drive wheel, a take up wheel, and an endless belt disposed about said drive wheel and said take up wheel. 9. A utility vehicle as set forth in claim 6 wherein said propulsion system includes a plurality of wheels mounted to said vehicle frame, said wheels receiving a driving input from said power source. 10. A utility vehicle as set forth in claim 6 including a mechanism for raising said platform upwards, off of said vehicle frame, said mechanism further moving said platform rearward such that it extends past said rear end of said vehicle frame. 11. A utility vehicle as set forth in claim 10 wherein said mechanism for raising said platform and moving said platform rearward includes a plurality of parallel link bars connected on one end thereof to said vehicle frame and on an opposite end thereof to said platform; and a power cylinder connected to said vehicle frame and said platform, said power cylinder operative to raise said platform on said plurality of parallel link bars. 12. A utility vehicle comprising: a vehicle frame, said vehicle frame having a front end and a rear end; a platform located on an upper surface of said vehicle frame; a power source located on said vehicle frame near said rear end; a propulsion system attached to said vehicle frame for moving said vehicle in response to an input from a control mechanism, said propulsion system connected to and receiving power from said power source; a foot assembly, said foot assembly connected to said vehicle frame and including first and second foot members, each of said foot members including a base portion and a leg portion; a power cylinder directly connected to and extending between said foot assembly and said vehicle frame, said power cylinder operative to move said foot assembly between a raised position and a lowered position wherein said base portion contacts the ground surface; and an implement supported on said platform. 13.
