The invention claimed is: 1. A dumping cart, including: a load carrying bed; a first axle rotatably supporting a first ground engaging wheel assembly; a second axle rotatably supporting a second ground engaging wheel assembly; and an articulated chassis pivotably shiftable between a load transport configuration and a load dumping configuration, including: a first chassis member operably coupled to the first axle; a second chassis member operably coupled to the second axle, the first and second chassis members being operably, pivotably coupled together along a chassis pivot axis; the first and second axles attached to said respective first and second chassis members in a fixed orientation and defining a first axle separation distance when said articulated chassis is in said load transport configuration and a second axle separation distance when said articulated chassis is in said load dumping configuration, said second axle separation distance being less than said first axle separation distance. 2. The dumping cart of claim 1, further comprising a plurality of first chassis braces and a plurality of second braces, said first and second braces coupling said first and second axles to said respective first and second chassis members. 3. The dumping cart of claim 1, further comprising a plurality of braces attaching the bed to the chassis. 4. The dumping cart of claim 1, in which the chassis pivot axis is behind one of the first and second wheel axles when the chassis is in the load dumping configuration. 5. The dumping cart of claim 1, in which the bed is pivotally attached to the chassis. 6. The dumping cart of claim 1, further comprising front and rear walls and a pair of side walls attachable to the bed. 7. The dumping cart of claim 6, in which the front and rear walls and the side walls are pivotally attached to the bed. 8. The dumping cart of claim 1, in which the first second axles further comprises a steering mechanism. 9. A dumping cart, including: a load carrying bed; a front axle rotatably supporting a front wound engaging wheel assembly; a rear axle rotatably supporting a rear ground engaging wheel assembly; and an articulated chassis including: a front chassis member operably coupled to the front wheel axle; a rear chassis member operably coupled to the rear wheel axle; and means for operably, pivotably coupling said front and rear chassis members together for shiftably supporting said bed between a load transport position and a load dumping position. 10. The dumping cart of claim 9, wherein said coupling means comprises a pivot. 11. The dumping cart of claim 10, in which said pivot is horizontally disposed behind said rear axle when said dumping cart is in said load dumping position. 12. The dumping cart of claim 10, in which said pivot is horizontally disposed between said front and rear axles when said dumping cart is in said load transport position. 13. The dumping cart of claim 9, further comprising a front wall, a rear wall, and a pair of side walls, said front wall, said rear wall, and said side walls attachable to said bed. 14. The dumping cart of claim 13, wherein said front wall, said rear wall, and said side walls are pivotally attachable to said bed. 15. The dumping cart of claim 9, further comprising a steering mechanism coupling said front axle to said bed. 16. A dumping cart, comprising: a bed; front and rear wheel assemblies, each front and rear wheel assembly comprising at least one wheel rotating about respective front and rear wheel axes; and a chassis supporting the bed and articulated at a chassis pivot, said chassis configurable between a load transport position and a load dumping position, wherein said chassis pivot is intermediate said front and rear wheel axes when said chassis is in said load transport position, and wherein said chassis pivot is behind said rear wheel axis when said chassis is in said load dumping position. 17. The dumping cart of claim 16, in which said chassis pivot is characterized by a chassis pivot axis. 18. The dumping cart of claim 17, in which the chassis pivot axis is behind the rear wheel axis when the chassis is in the load dumping position. 19. The method of claim 3, further comprising forming front and rear walls and a pair of side walls attachable to the bed.
