Abstract

Plowing means for dislodging, uplifting and sweeping aside mines are attad to a crossbeam and located on either side of float shoes that slide along the ground and adjust to maintain a chosen depth of plow. The crossbeam is connected to the front of a vehicle by pushbars that attach to a frame mounting on the vehicle. The float shoes are caused to move by powered adjusting means mounted on the crossbeam and controlled by sensing means that monitor the attitude of the vehicle relative to the pushbars and generate a control signal for maintaining the plow depth.
