A tractor implement lift height amplifier including a lift arm mounted on a rock shaft on a tractor and having links connected to the arm and with the links connected with the draft arms attached between the tractor and a draft implement. The lift arm and links are arranged for abutting engagement when the lift arm is pivoted upwardly, to thereby effect a solid, rather than articulated, lift connection so that the additional upward pivoting of the lift arm will induce maximum lifting of the implement itself.
