<p>A track system for a vehicle traveling on a ground. An endless track is connected to a frame by a plurality of wheels rotatably connected to the frame. A track contact area portion supports the vehicle on flat ground. A corner idler wheel is rotatably mounted on a shaft movably connected to the frame by an adjuster. A track portion extends from the corner idler wheel towards the contact area portion defining an attack angle with respect to the flat ground. The corner idler wheel is thereby movable at least between a first position having a first track tension and a first attack angle, and a second position having a second track tension and a second attack angle. The first and the second track tensions are substantially the same. The second attack angle is larger than the first attack angle. Vehicles having the track system are also disclosed.</p> |
