An apparatus for transferring load between: (a) a towing tractor which includes: (i) a three-point linkage which includes three linkage arms (4, 5, 6), and associated hydraulic draft control system; and (ii) a tow-bar (90); and (b) a towed above ground implement which includes a draw-bar (40) which attaches to the tow-bar (90) of the tractor; characterised in that the apparatus includes a shock absorber (17) which is: (iii) connected at one end thereof to at least the two lower arms (4, 5) of the three-point linkage; and iv) at the other end thereof connected to the draw-bar (40) of the towed implement in a manner that allows the draft control system of the tractor to be activated so as to transfer load between the tractor and the implement, as is required to maintain the desired wheel slippage of the traction axle of the tractor whilst towing the implement.
