- Model R Series - Rotary Disc Headers


If you’ve been looking for a header that cuts alfalfa at speeds up to16 MPH (26 km/h) and powers through 12' (3.6 m) of cane or a heavy winter forage crop – MacDon’s R85 Rotary Disc provides all this and more. This next generation rotary disc machine has been significantly improved in almost every important area including frame strength, cutting angle, disc pattern, header flotation and conditioning. There’s even MacDon’s new Double Windrow Attachment that allows you to place up to 48' (14.6 m) of crop into a single windrow by combining three 16' (4.9 m) conditioned windrows. The result is a machine that delivers greatly improved cutting, crop handling and windrow formation, especially in tough, heavy or wet crop conditions.

  • Hydraulically driven header with high capacity
  • Lower daily and annual maintenance requirements due to fewer moving parts than some competitive disc mowers
  • Improved header float with fine-tune hydraulic adjustment on-the go
  • Heat treated cutting and wear components
  • separate replaceable guards to protect cutterbar between discs


Improves the placement of the cutterbar in relation to the ground, thereby reducing wear on the cutterbar and enhancing the in field performance of the header.


MacDon’s double windrow attachment feature lets you lay up to 48' (14.6 m) of crop in a single windrow. This is ideal for today s large forage harvesters, and can translate into significant time and fuel savings for producers who employ this feature.


Attached behind the cutterbar to reduce wear on the cutterbar wear plate and improve the movement of the header over uneven terrain, as well as in sand or firm soil conditions. Optional for A and 16' R Series.
