This invention consists of a vehicle for handling multi-furrow ploughs, which are very heavy and are equipped with only one wheel in the rear, when not attached to a tractor during operation. It consists of a two wheeled cart provided with two hooks attached to the main body of the cart, by means of which the front end of the plough is picked up and held, and a central arm for pulling the cart which is swivably attached to the main body. A ratchet operated cylinder having two oppositely threaded screws, one going in or out at each end simultaneously, is swivably attached to the arm and to the main body of the cart, so that turning the ratchet in one direction expands the distance between the screw ends thus lowering the hook towards/the ground to pick up the front end of the plough, and turning it in the opposite direction reduces that distance and lifts the hooks and front end of the plough to make it mobile. A variation of the above invention shows the hooks being attached to a pair of hydraulic jacks, thereby replacing the said ratchet operated cylinder and the swivel attachment of said central arm.
