An elongated beam assembly for a tracked suspension includes an inverted "U" shaped member having a first upper surface disposed at an outwardly descending lateral angle; and a plurality of track wheels coupled to the bottom of the member and disposed inside the member. In another arrangement the assembly includes a curved plate disposed between and fixed to both an inner wall and outer wall of the "U" shaped member, with the free edge of the curved plate extending outward over the top edge of the outer wall.

We claim: 1. An elongated beam assembly for a tracked suspension, the beam assembly having front and rear portions, the beam assembly comprising: an inverted "U" shaped member, the inverted "U" shaped member further comprising generally vertical inner and outer walls, the inner and outer walls each having inner and outer surfaces, the inner and outer walls each having a top edge, the inner and outer walls are coupled together by a curved plate adjacent the rear portion, wherein the curved plate has a top and bottom surface and inner and outer lateral edges, wherein the inner lateral edge is coupled to the outer surface of the inner wall and the top edge of the outer wall is coupled to the bottom surface of the curved plate such that the outer lateral edge extends laterally outward beyond the top edge of the outer wall; a plurality of track wheels coupled to the bottom of the member and disposed inside the member; and a drive wheel mounting plate having an opening for mounting of a drive wheel and a curved edge portion, the drive wheel mounting plate is coupled to the curved plate such that the curved edge portion extends along the top surface of the curved plate and that the drive wheel mounting plate extends substantially perpendicular from the top surface of the curved plate. 2. The assembly of claim 1, further comprising: a track drive wheel supported on the member, wherein the curved plate is spaced apart from and curves around the periphery of the drive wheel. 3. The assembly of claim 1 wherein the plurality of track wheels are roller wheels, the beam assembly further comprising: a front idler wheel fixed to a front end of the member and a rear idler wheel fixed to a rear of the member adjacent the rear portion of the beam assembly. 4. The assembly of claim 1, further comprising: front and rear supports fixed to the member, the front and rear supports being configured to fix the member to a chassis of a tractor. 5. The assembly of claim 4, wherein each of the front support and the rear support further comprise: a bracket configured to be fixed to a chassis side wall and to a bottom of the chassis; and a beam fixed to both the bracket and the member, wherein said beam extends laterally outward away from the chassis to the member. 6. The assembly of claim 1, further comprising: a track drive wheel fixed to the member, wherein the curved plate is spaced apart from and curves around the periphery of the track drive wheel. 7. The assembly of claim 1, wherein the curved plate defines an axis of curvature that is coaxial with a central axis of a drive wheel. 8. The assembly of claim 1 wherein a portion of the curved plate extends around a periphery of a drive wheel and defines a portion of a right circular cylinder. 9. The assembly of claim 1, wherein the plurality of track wheels are roller wheels, the assembly further comprising a front idler wheel fixed to a front end of the member and a rear idler wheel fixed to a rear of the member adjacent the rear portion of the beam assembly. 10. The assembly of claim 1, further comprising: a front support and a rear support fixed to the member and configured to fix the member to a chassis of a tractor. 11. The assembly of claim 10, wherein each of the front support and the rear support further comprise: a bracket configured to be fixed to a side wall and to a bottom of the chassis; and a beam fixed to the bracket and to the member, wherein said beam extends laterally outward away from the chassis to the member. 12. The assembly of claim 10, wherein the outer wall has an upper portion bent to form a first upper surface, the first upper surface disposed adjacent the front portion at an outwardly descending lateral angle, the inner wall has an upper portion bent over to form a second upper surface that is horizontal when measured in a lateral direction, the second upper surface disposed adjacent the front portion. 13. The assembly of claim 12, wherein the second upper surface abutting the first upper surface over substantially its entire length, wherein the second upper surface is disposed at a forwardly descending longitudinal angle, and further wherein the first upper surface is also disposed at the forwardly descending longitudinal angle. 14. The assembly of claim 1, wherein the outer wall has an upper portion bent to form a first upper surface, the first upper surface disposed adjacent the front portion at an outwardly descending lateral angle, the inner wall has an upper portion bent over to form a second upper surface that is horizontal when measured in a lateral direction, the second upper surface disposed adjacent the front portion. 15. The assembly of claim 1, wherein the member comprises a first elongated and longitudinally extending top surface disposed at both a forwardly descending longitudinal angle of between 5 and 20 degrees, and at an outwardly descending lateral angle of between 40 and 50 degrees.
