A unit for attachment to a tractor, particularly at the front of a tractor, enables any tractor quickly and easily to be equipped with a three-point linkage for coupling to implements and ancillary equipment, A linkage comprising a top link, two lower links, connecting means and one or more actuators is fitted as a unit to a frame which can be secured to the tractor. Preferably all three links are moved jointly by the actuator through the connecting means therebetween. The actuators may comprise two hydraulic rams positioned one at each side of the unit leaving the centre of the unit open and free for auxiliary equipment. |
