Abstract
The present invention provides an endless track belt allowing an enhanced traction of a tracked vehicle over a range of surface conditions, by providing tread on the ground-engaging surface having a top part and a bottom part, the top part being flexible, whereas the bottom part is rigid. On a loose underground such as powder snow, the flexible top part of the tread bends to apply a compacting action on the underground, while, on a packed underground, the rigid bottom part of the tread has a grabbing action on the underground.
