A level indicator for a disk harrow or the like having a motorized on-the-go leveling adjustment. A small diameter flexible cable is attached to the spring retainer which bears against one end of the coil spring on an adjustable link structure located between pivoting hitch structure and the adjustable ground wheels. The opposite end of the cable is attached to a slide which is free to move vertically in a bracket fixed to the motor mounting bracket. The weight of the slide maintains tension on the cable and as the motor is activated to move the spring retainer relative to the motor mounting bracket, the cable moves the slide vertically to provide an indication of the leveling adjustment. The consistent relationship between the spring retainer and the motor bracket at a given adjustment position provides an easy to read indication even though the entire leveling system may be moving relative to the machine frame.
