A rugged, compact machine well-suited for straight main line work in municipalities, universities, institutions, and industry.

Rod rotates at 133 RPM in forward and reverse at full throttle. Spring-loaded throttle control is hand operated. Varies rod speed within each speed range. Returns engine speed to idle and disengages clutch when operator releases throttle. Adjustable torque limiter minimizes kinking of rods and excessive torque through transmission system.
