I claim: 1. A track suspension system for a skid steer loader, comprising: an undercarriage adapted to be attached to a skid steer loader; a first drive wheel adapted to be attached to a first wheel axle or a drive shaft of the skid steer loader; a front roller movably and rotatably attached to a f
I claim: 1. A track suspension system for a skid steer loader, comprising: an undercarriage adapted to be attached to a skid steer loader; a first drive wheel adapted to be attached to a first wheel axle or a drive shaft of the skid steer loader; a front roller movably and rotatably attached to a front portion of said undercarriage; a rear roller movably and rotatably attached to a rear portion of said undercarriage; a plurality of lower idlers movably and rotatably attached to said undercarriage; a track movably extending about said first drive wheel, said front roller, said rear roller and said plurality of lower idlers; and a front walking beam pivotally attached to said undercarriage, a front connector rotatably supporting said front roller, and a front upper member pivotally connected to the undercarriage and a first portion of said front connector, wherein said front walking beam rotatably supports one of said plurality of said lower idlers and wherein an opposing end of said front walking beam is pivotally connected to a second portion of said front connector. 2. The track suspension system for a skid steer loader of claim 1, including a middle walking beam pivotally attached to said undercarriage, wherein said middle walking beam rotatably supports a pair of said plurality of said lower idlers. 3. The track suspension system for a skid steer loader of claim 1, including a rear walking beam pivotally attached to said undercarriage, a rear connector rotatably supporting said rear roller, and a rear upper member pivotally connected to the undercarriage and a first portion of said rear connector, wherein said rear walking beam rotatably supports one of said plurality of said lower idlers and wherein an opposing end of said rear walking beam is pivotally connected to a second portion of said rear connector. 4. The track suspension system for a skid steer loader of claim 1, including a tension idler movably and rotatably connected to said front portion of said undercarriage. 5. The track suspension system for a skid steer loader of claim 4, including a tension connector pivotally attached to said undercarriage and rotatably supporting said tension idler. 6. The track suspension system for a skid steer loader of claim 5, including a tension actuator connected between said tension connector and said undercarriage, wherein said tension actuator provides a biasing force upon said tension connector for causing said tension idler to maintain said track in a substantially taut state. 7. A track suspension system for a skid steer loader, comprising: an undercarriage adapted to be attached to a skid steer loader; a first drive wheel adapted to be attached to a first wheel axle or a drive shaft of the skid steer loader; a front roller movably and rotatably attached to a front portion of said undercarriage; a rear roller movably and rotatably attached to a rear portion of said undercarriage; a plurality of lower idlers movably and rotatably attached to said undercarriage; a track movably extending about said first drive wheel, said front roller, said rear roller and said plurality of lower idlers; and a rear walking beam pivotally attached to said undercarriage, a rear connector rotatably supporting said rear roller, and a rear upper member pivotally connected to the undercarriage and a first portion of said rear connector, wherein said rear walking beam rotatably supports one of said plurality of said lower idlers and wherein an opposing end of said rear walking beam is pivotally connected to a second portion of said rear connector. 8. The track suspension system for a skid steer loader of claim 7, including a middle walking beam pivotally attached to said undercarriage, wherein said middle walking beam rotatably supports a pair of said plurality of said lower idlers. 9. The track suspension system for a skid steer loader of claim 7, including a front walking beam pivotally attached to said undercarriage, a front connector rotatably supporting said front roller, and a front upper member pivotally connected to the undercarriage and a first portion of said front connector, wherein said front walking beam rotatably supports one of said plurality of said lower idlers and wherein an opposing end of said front walking beam is pivotally connected to a second portion of said front connector. 10. The track suspension system for a skid steer loader of claim 7, including a tension idler movably and rotatably connected to said front portion of said undercarriage. 11. The track suspension system for a skid steer loader of claim 10, including a tension connector pivotally attached to said undercarriage and rotatably supporting said tension idler. 12. The track suspension system for a skid steer loader of claim 11, including a tension actuator connected between said tension connector and said undercarriage, wherein said tension actuator provides a biasing force upon said tension connector for causing said tension idler to maintain said track in a substantially taut state.
