Straightline Reciprocal Action. 2-Cylinder, oversized common piston, powers twin-drive vertically-engaged gears with synchronized strokes so smooth that the 2000 VA/DF gets lighter with use. Precision-built, the HUSTLER does almost anything but finish and paint the surface. Rugged, but almost delicate in performance. With VA/DF options it becomes the healthiest, most productive straightline available. Pad size 2 3/4" x 16". Optional Pierce Plate available Separately.
