摘要： The telescopic adjusting crank for adjusting a lift link of a tractor 3-point hitch consists of an upper outer tube, an inner shaft and a slide tube wherein the slide tube is fixedly connected to the upper end of the inner shaft and is slidably positioned within the upper outer tube. The slide tube is of a greater dimension than the shaft so that a gap remains between the outer tube and the inner shaft. The outer tube and the sliding tube are of such lengths that the sliding tube remains completely within the outer tube through the full range of movement.
