An apparatus for controlling the depth of a hoe bucket, including a hoe bucket defining a cutting edge, an elongated member pivotably connected to the bucket, an actuator operationally connected to the elongated member, an electronic controller operationally connected to the actuator, and a position sensor operationally connected to the cutting edge and operationally connected to the electronic controller. The actuator may be energized to pivot the elongated member to a position adjacent the cutting edge for engaging ground, and positioning of the elongated member adjacent the cutting edge prevents the cutting edge from digging ground.
