Variable working width plough

摘要

The plow comprises a chassis composed of a front chassis (7a) and a rear chassis (7b) on which are mounted the plowing bodies. An intermediate part (8) articulated between the front and rear chassis is connected to support wheels (11). The orientation of the front and rear chassis parts relative to the intermediate part is adjusted by rods (20a, 20b) connecting the chassis parts to a movable part (21) mounted on the intermediate part. Direct or indirect action on the rods enables the chassis parts to be displaced.
