The device is mounted on a seeder provided with a hopper, with a seed distributor and with a plowshare or work disk. It comprises two lateral gauge wheels mounted on two bearings borne by two arms pivotably articulated around an axis on the chassis of the seeder. A class 1 lever formed from a rod is extended by two sliding sleeves articulated respectively at its middle around a ball-joint adjustable in position with respect to the chassis and at its two ends around the two other ball-joints fastened to the oscillating support arms. The device is useful in agricultural machines having a plowshare or work disk.
