The only 2-Cylinder, common piston straightline with vertically-engaged, twin-drive gears
Lack of "rolling gears" common to all other straightlines eliminates "humping and jumping" at the end of each reciprocal stroke
Two in-line cylinders, micro-honed to eliminate cylinder-wall drag, power an oversized high-alloy piston
Double rack and pinion gear assemblies give twice-normal gear contact for maximum balance and thrust
These precision assembled components make the Hustler a superb all-purpose straightline with synchronized strokes so smooth and powerful it gets lighter with use.
