The implement height adjuster is configured to be coupled to a planter unit or other equipment towed behind a tractor and includes a motor, a gear reduction transmission coupled to the motor, and a flexible output shaft, that is coupled to the transmission at a first end and to the implement to be adjusted at a second end. The flexible output shaft allows the motor of the implement height adjuster to be mounted in various positions on the equipment. The gear reduction transmission or motor includes a position sensor that allows the operator of the tractor to know the position of a particular implement without requiring a visual inspection of the implement. A control panel is used to manage the vertical adjustment of one or a series of implements. The control panel provides power to the implement height adjusters and uses the output signals of the sensor to determine the exact location of each the tillage implement.10-13-2011
