A machine for planing large wood timbers or other heavy wood products easily by self-propelling along the work piece and planing the wood surface as it goes. The machine has a set of planer knives driven by a power source, a set of rollers before and after the knives for self feeding the planer down the work, and a flat surface in front and behind the rollers and cutting knives for stability and smoothness. The roller may also be adjusted in relation to the cutters for depth of cut and/or slightly angling the cut to one side. Centering guides keep the unit balanced on the work piece. There can be multiple feed rollers in front and behind the planer knives.
