Abstract An agricultural implement wherein cultivator means such as plowshares are attached to mounts (7) on a frame (1) which can be adjusted for different plow strip widths by means of a hydraulic cylinder (15) and a parallel strut (10), said frame (1) being pivotally attached (3) to a drag beam (4) that is adapted to be pivotally mounted (5) on a tractor hitch (6) for coupling to a tractor. A first link (12) is provided which is pivotally attached (13) to the tractor hitch (6) and to the frame (1), such that when the frame (1) is pivoted for changing the plow strip width, all of the plowshare mounts (7) will be displaced correctly in relation to each other while at the same time the first mount (7) is displaced correctly in relation to the tractor centerline. A second link (20) is also provided, pivotally attached (19, 21) to the strut (10) and the tractor hitch (6), such that when the frame (1) is pivoted for changing the strip width, all of the plowshare mounts (7) are pivoted in relation to the frame (1) such that the mounts (7) are always oriented in the same way and correctly in relation to the direction of driving.
