Lift structure particularly useful with front mounted implements for providing both lift and weight transfer functions from a single valve. The valve acts as an adjustable bleeder for the lift cylinder and includes a control knob which is movable both axially and rotationally to respectively provide lift and adjustable flotation. The valve is normally biased to an adjustable orifice position for operating the implement in a lowered, flotation position. To momentarily lift the implement, the operator moves the control knob against the bias to direct flow to the lift cylinder thereby raising the implement off the ground. When the operator releases the valve, it automatically returns to the preset orifice position to provide the desired flotation.
