摘要：A device for adjusting the distance between soil working tools such as plowbodies (5) disposed beside each other and fitted to sleeves (7) movable along a bar (3).Slewing brackets (11, 14, 15) for defining the movements of the sleeves (7) along the bar(3) are arranged articulatedly between the sleeves (7) so that the relative movementbetween the two outermost sleeves on the bar is a (n-1), where a is the distance of themovement between two adjacent sleeves (7) and n is the number of sleeves. A hydraulicpiston-cylinder unit is arranged to provide the motion of the sleeves (7) along the bar (3).
