The 509 Commercial / Residential extruder is powered by a 4-horsepower Honda engine with centrifugal clutch and speed adjustment. Smooth, hard compaction handles aggregate easily, cutting trowel work time and eliminating voids. The undercarriage, forms and rams are interchangeable for residential and commercial flexibility. The machine can be adjusted to suit for long strokes, medium strokes, fast speeds or slow speeds. Its wide stance, large tires and low center of gravity increase stability. Residential and commercial slip forms are available. Mortar sand, concrete sand and stone aggregate all come out firm and solid with fewer voids. This machine is available in a powder coat finish or stainless steel.
