A frame assembly is described including a tunnel, an engine cradle disposed forward of the tunnel and connected thereto, and a sub-frame disposed forward of the engine cradle and connected thereto. A forward support assembly extends upwardly from the subframe. An upper column extends upwardly from the engine cradle to connect with the forward support assembly. A rear brace assembly extends upwardly from the tunnel to connect with the forward support assembly and the upper column. In one embodiment, the frame assembly further includes an engine disposed in the engine cradle. An endless track is operatively connected to the engine and disposed beneath the tunnel for propulsion. A pair of skis is operatively connected to a steering device for steering. In another embodiment, the frame assembly further includes an engine disposed in the engine cradle. A rear wheel is operatively connected to the engine and disposed beneath the tunnel for propulsion, and two front wheels are operatively connected to a steering device for steering.

The frame assembly of claim 2, further comprising a steering bracket connected to at least one of the rear brace assembly and the upper column, said steering bracket supporting a steering shaft. 9. The frame assembly of claim 5, further comprising a steering bracket connected to at least one of the forward support assembly and the rear brace assembly, said steering bracket supporting a steering shaft. 10. The frame assembly of claim 8, wherein the steering bracket includes a plurality of holes that selectively position the steering shaft in a plurality of positions. 11. The frame assembly of claim 9, wherein the steering bracket includes a plurality of holes that selectively position the steering shaft in a plurality of positions. 12. The frame assembly of claim 1, further comprising a second left leg and a second right leg, wherein the left leg and the right leg of the rear brace assembly and the second left leg and the second right leg of the frame assembly from a pyramidal structure when viewed from above. 13. The frame assembly of claim 12, further comprising: a sub-frame disposed forward of the engine cradle and connected thereto; and a forward support assembly extending rearwardly and upwardly from the sub-frame, the forward support assembly including the second left leg and the second right leg, wherein the second left leg and the second right leg of the forward support assembly and the left leg and the right leg of the rear brace assembly form an apex above one of the engine cradle and the tunnel. 14. The frame assembly of claim 12, further comprising: an upper column extending upwardly from the engine cradle, the upper column including the second left leg and the second right leg, wherein the second left leg and the second right leg of the upper column and the left leg and the right leg of the rear brace assembly form an apex above one of the engine cradle and the tunnel. 15. The frame assembly of claim 13, further comprising a steering bracket connected to at least one of the forward support assembly and the rear brace assembly, said steering bracket supporting a steering shaft. 16. The frame assembly of claim 15, wherein the steering bracket includes a plurality of holes that selectively position the steering shaft in a plurality of positions. 17. The frame assembly of claim 14, further comprising a steering bracket connected to at least one of the rear brace assembly and the upper column, the steering bracket supporting a steering shaft. 18. The frame assembly of claim 17, wherein the steering bracket includes a plurality of holes that selectively position the steering shaft in a plurality of positions.
