R1 Rotary Combine

Revolutionary, patent-pending top feed rotor harvests research plots faster, cleaner, and gentler than comparable research combines.

Get the most out of your research plots! The R1 plot combine's advanced, rotary threshing and high torque design enables earlier harvest of large green plants, tough stems and high plant foliage. This greatly increases the harvest window, allowing you to start harvesting plots earlier and finish faster.

The R1 operates at faster harvest speeds while producing less seed damage, cleaner samples, easier cleanout, and lower seed loss than competitive models. With its easy to change concaves and simple, interchangeable head design, the R1 is ideal for use in seed research programs with multiple crops.
