A planer apparatus for cutting a selected upper portion of a roadway surface to coincide with a preselected reference plane, comprising a main frame drivingly supported by a drive assembly, the main frame carrying a planing assembly comprising a rotating cutter drum assembly and a cutter drive assembly. The cutter drive assembly comprises a pair of cutter power assemblies which are disposed on one side of the main frame and which are connected to a rotating hub member. The rotating hub member is carried by load-bearing hub support surfaces, with the rotating hub member rotatably driving the cutter drum assembly. The planer apparatus further comprises an upper material lifting conveyor for elevating and moving roadway material disengaged from the roadway by the planing assembly. The upper material lifting conveyor features an upper conveyor cover connecting the side members of the upper conveyor frame, with the conveyor motor assembly mounted on the upper conveyor frame between the side members. A spray bar assembly cleans the non-transport surface of the conveyor belt of the upper material lifting conveyor. The planer apparatus may be powered either by a main or auxiliary drive unit, with the exhaust discharge system of the main drive unit disposed in heat-transferring relationship to a water spray system providing dust control for the apparatus.
