A spring downforce actuator adjustment assembly includes a spring exerting a downforce on an object. Also included is a ball screw extending within an interior location defined by the spring. Further included is a ball nut threaded to the ball screw and in abutment with an end of the spring. Yet further included is a coupling connectable with an input device to rotate the ball screw, rotation of the ball screw translating the ball nut therealong and adjusting an effective length of the spring.
