Features

MEGACUTTER™ DISC CUTTERBAR

STANDARD QUICK-CHANGE KNIFE SYSTEM KEEPS YOU CUTTING SHARP

Sharp knives give you the clean cut you want with less crop left behind. As a result, you harvest more tons, get fast regrowth and assure your forage quality for the next cutting. Keeping knives sharp is easy with the standard quick-change knife system. It allows you to change damaged knives fast or flip an entire set and get back to mowing pronto to keep on your mowing schedule.

CONDITIONING SYSTEMS

STEEL FLAIL TINE CONDITIONING

Steel flail tines are positioned at an angle to the rotor’s center, providing increased outward crop pressure against the adjustable conditioning hood and improving swath and windrow formation. You can adjust the hood to change the conditioning intensity. The semi-swinging flail tines allow obstructions to pass, for better protection compared to fixed poly or steel tines. And unlike conventional, free-swinging tines, they cannot swing back over center, but are held in the ideal place by centrifugal force for efficient and effective conditioning and uniform swath and windrow formation.

PRECISION TECHNOLOGY

FASTER SPEEDS, FASTER RESPONSE

Automatic steering control maintains pass-to-pass accuracy, allowing operators to use faster working speeds and reducing fatigue. When operators are free from making continuous manual adjustments, they are better able to react to obstructions hidden in the field.
