A vertical lift and tilt control for plows which is particularly suitable for laying cable, pipe and the like underground. The vertical lift mechanism includes a mast assembly having a generally vertical rail and a slide frame slideably mounted on the rail. The plow assembly is supported on the slide frame and a power means, such as a piston, is connected to the mast and slide frames for raising and lowering the plow assembly. The mast assembly is pivotally supported on a suitable vehicle and a second power means, such as a piston, is pivotally connected to the vehicle and the mast assembly for adjusting the tilt or attack angle of the plow blade.
