New Holland MegaCutter 512 Front Mounted Mower Conditioner

Double tap to zoom



With its big 11-foot, 10-inch cut, the MegaCutter™ 512 clears a wide path—one that’s 16% wider than competitive 10-foot models—and provides more mower overlap, eliminating the need for complicated side-shift mechanisms. The wide cut also means you can set the tractor wide for fast drying of the center swath so there are no compromises.

Challenging conditions are no problem for the MegaCutter 512 cutterbar. It’s fully welded with integral box beam support to provide flexibility and support. There are three levels of protection that safeguard against cutterbar damage in the event of a collision while mowing: 1- Round disc profile produces less wind disturbance and resists stone jamming, 2- Discs are set back for less chance of direct collision, 3- Integrated shear-key system provides disc drive protection.

To cut cleanly and remain well protected, front mounted mower-conditioners must provide a broad range of suspension travel. The rugged and reliable spring suspension system found on the MegaCutter™ 512 front mounted mower-conditioner does exactly that and easily adjusts to suit your working speeds and field conditions. This advanced suspension provides remarkable flotation, with a working range over 27 vertical inches and up to 24 degrees of angular movement to adapt to the most challenging terrain. Its innovative geometry and linkage allows the cutterbar to move up and back, while reducing cutterbar angle simultaneously to clear obstacles, protect valuable crop stubble, and reduce skid shoe wear. The reliable system does it all without hydraulic accumulators or cylinders which can leak down while mowing, so you can mow with confidence knowing You're protected.

The main gearbox is ambidextrous so it can be set for clockwise (CW) or counter-clockwise (CCW) rotation by inverting the 1000-rpm main gearbox. The factory setting for CCW rotation with 1-3/8’’, 6-spline PTO works with New Holland T7.270 tractor. An additional 1-3/8’’, 21-spline yoke and the alternate CW PTO rotation setting are required for New Holland T8 Series tractors.
