Abstract
A management system is disclosed for controlling the tension of an endless track by regulating the hydraulic pressure in a hydraulic jack acting on a roller serving to tension the track. The tension management system comprises two accumulators of different capacity that are connected to the jack. Both accumulators are in permanent direct communication with the jack and the larger accumulator is preloaded to a higher pressure than the smaller accumulator.
