When processing round logs to form square or profiled lumber, a serious problem is the adjusting of the spacing between cutter heads to accommodate logs of different diameters. A simple apparatus for solving the problem includes opposed wheels for feeding a log longitudinally through the apparatus, a first saw for cutting a groove in the log which receives a guide bar for preventing rotation of the log during passage through the apparatus, two pairs of opposed cutter heads for squaring opposed sides of the log, the cutter heads incorporating fully enclosed drives for simultaneously adjusting the spacing between opposed cutter heads for accommodating logs of different diameters, guide bars connected to the cutter heads for engaging the log downstream of the cutter heads in the direction of log travel for guiding the log through the remainder of the apparatus, and either profiling heads for profiling a squared log or saws for cutting the squared log into boards.
