Abstract: A log peeling machine having a rotatable peeler drum assembly located intermediate a log infeed conveyor apparatus and an outfeed conveyor apparatus both of like construction. Each conveyor apparatus includes a conveyor assembly disposed beneath the log being peeled and a cooperating hold down assembly disposed thereabove which jointly confine and propel the log along an axis coaxial with the peeler drum. Pairs of hydraulic cylinders position both the conveyor assembly and the hold down assembly of each conveyor apparatus for uniform travel of same toward and away from the projected axis of the cutter drum. The hydraulic cylinders are in fluid, series communication to assure uniform fluid displacement and synchronized travel of the conveyor and hold down assemblies. The peeler drum assembly swingably mounts cutter head assemblies served by a rotating tank structure. Radio transmissions control peeler drum operation.
