Suspension device for a plow

Abstract

In a plow, particularly a reversible plow, one has aimed at a plow enabling plowing in hard soil affording very heavy resistance against the plow bodies (2), using comparatively small material dimensions and corresponding light weight of the plow. For this purpose, the plow beam (3), at the front end thereof, is pivotally mounted on the plow frame (1) and, somewhat spaced behind the pivot (4), a rotation restricting shear pin (5) is secured to the plow frame (1). The plow beam (3) is coupled to a lever (6) which, spaced from its connection point (7) to the plow beam (3), possibly via a longitudinally adjustable stop member (10), is resting supportingly on an adjacent plow beam portion. The lever (6) is, spaced from its said connection point (7) as well as from said supportingly resting portion/stop member (10), linked to an elastic compliant, resilient damper (11). Additionally, said damper (11) is connected to the plow frame (1) or to an element connected thereto. The last-mentioned element may with a reversible plow be constituted by a further lever (6') assigned to a further plow beam (3') carrying a plow body (2') of its own. The last-mentioned plow body (2') together with the first-mentioned plow body (2) may thereby form a plow body pair (2,2') in a reversible plow.
