초록

A track tensioning assembly for adjusting tension on a drive track chain of a work machine includes a main housing defining a main chamber. The track tensioning assembly also includes a recoil piston positioned within the main chamber. The recoil piston has a recoil central passage defined therein. The track tensioning assembly further includes a master piston secured within the recoil central passage. The master piston (i) increases fluid pressure in the main chamber when the master piston is positioned in a first master position, and (ii) decreases flu...
