Abstract
A continuous track assembly having forward and rearward track engaging wheels with a intermediate track engaging wheel position between them. A continuous track extends over the wheels. A foldable frame journals the wheels and is displaceable between a position where the track engaging wheels are in substantially the same plane and another position in which they are in a triangular configuration.

A continuous track assembly comprising;
- a forward track engaging wheel;
- a rearward track engaging wheel;
- an intermediate track engaging wheel positioned between said forward and rearward wheels;
- a continuous track extending around said wheels;
- a foldable frame journaling said wheels and displaceable between a first position wherein said wheels are substantially on a same plane and a second position wherein the wheels form a triangular configuration;
- and
- an actuator interconnecting between said foldable frame for displacing said foldable frame between the first and second position,
- wherein said foldable frame is pivotal about said intermediate wheel, and
- wherein said intermediate track engaging wheel is in line with a structural connection for said continuous track assembly.
