The Marshalltown 600CM Mortar/Plaster Mixer with 8 HP Gas Engine and 6 Cubic Ft. Mixing Capacity represents Marshalltown's heavy-duty mixers. It features a reinforced square tubular frame with a welded steel yoke for long-term rugged use. The wheel and hand brake tilting mechanism allow the tilt wheel to rotate the drum in infinite mixing positions, moving in the same direction as the drum. The frictional hand brake locks the drum in place in any position. Cast iron ring gear and tapered roller bearings deliver smooth performance. The Quad-Mixing system utilizes a 4-piece, replaceable paddle and blade combination that creates 4 different mixing patterns for a more consistent mix. The high-speed tow kit is standard with 13in. wheels and 25in. O.D. tires. 25in. discharge height. 18in. drum opening. 25 RPM drum rotation. Steel "U" spring suspension.
