Abstract
By providing an electronic control system in communication with a hydraulic system for adjusting an angle of smoothing tools of a harrow, the smoothing tools may be adjusted more quickly and on the go, including from a tractor cab, for optimum field leveling during a tilling session. The control system may include a hydraulic control valve in communication with a linear actuator. The linear actuator may be in communication with a slide bar disposed in a channel. By configuring multiple bars of a harrow to achieve an angle of rotation defined by the slide bar, the angle of rotation for smoothing tools of the harrow may be precisely controlled by the control system.
