This invention relates to endless tracks and systems used to propel tracked vehicles [i.e., vehicles which use endless tracks rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved split wheel design and installation process therefore. The track is made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tension wheel. A new step by step methodology allows the endless track to be installed and used more efficiently when the tension wheel or the drive sprocket is replaced by a split wheel.

The interlocking seating system of claim 5 wherein said seat modules are formed of plastic polymers.7. The interlocking seating system of claim 6 further comprising end caps adapted for placement at an aisle of a seating row, said end caps include positions for receiving numbering and advertising plates.8. The interlocking seating system of claim 4 wherein said openings defined through said tab of said interior seat module comprise a front elongated slot and a rear elongated slot, and wherein said rear slot is longer than said front slot.9. The interlocking seating system of claim 4 wherein said openings defined through said tabs of said interior seat modules are notches.10. A seat module for installation on a support comprising: a one-piece body member having a first and a second engagement member disposed at a first and an opposing second side of said body member, respectively; said first and second engagement members further including openings therethrough for receiving fasteners; wherein an engagement member of a first said seat module is adapted to receive an engagement member of a second said seat module, thereby allowing the interlocking and placement of said first and said second seat modules in a side by side relationship, to be secured to said support by fasteners through said openings; and wherein said interlocked first and second seat modules are adapted to substantially pivot relative to one another; wherein said body member provides a recessed area for receiving a plate having indicia thereon; wherein said first engagement member comprises a tab and said second engagement member comprises a blind rabbet; wherein said tab includes a rib disposed thereon, and said rib impinges a contacted surface of a blind rabbet of an adjacent seat module after assembly, thereby discouraging relative movement between said adjacent seat modules. 11. A seat module comprising: a one-piece body member having a first and a second engagement member disposed at a first and an opposing second side of said body member, respectively; said first and second engagement members further including openings therethrough for receiving fasteners; wherein an engagement member of a first said seat module is adapted to receive an engagement member of a second said seat module, thereby allowing the interlocking and placement of said first and said second seat modules in a side relationship, to be secured to said support by fasteners through said openings; wherein said openings defined through said first engagement member comprises a front slot and a rear elongated slot wherein said rear elongated slot is longer than said front elongated slot; and wherein said openings defined through said second engagement member are apertures. 12. A seat module for installation on a support comprising: a one-piece body member having a first and a second engagement member disposed at a first and an opposing second side of said body member, respectively; said first and second engagement members further including openings therethrough for receiving fasteners; wherein an engagement member of a first said seat module is adapted to receive an engagement member of a second said seat module, thereby allowing the interlocking and placement of said first and said second seat modules in a side by side relationship, to be secured to said support by fasteners through said openings; and wherein said interlocked first and second seat modules are adapted to substantially pivot relative to one another; wherein said body member provides a recessed area for receiving a plate having indicia thereon; wherein said first and second engagement members comprise at least one blind rabbet recess in a side of said body member. 13. A seat module for installati
