A tree delimbing apparatus comprises a frame including mounting elements for supporting the frame on the front end of a conventional skidder. The frame includes four beams arranged in a rectangle with a front and a rear beam transverse to the direction of motion of the vehicle. Between the front and rear beams are mounted five delimber elements each supported on the underside of the front and rear beams and each including a hub and four blades which project radially outwardly from the hub. Each element is free to rotate around its axis with its blades passing close to but spaced from the next adjacent hub. The free rotation of the hubs provides an improved delimbing action.
