The Class VIII RT490 combine was designed to be rugged, reliable and simple to maintain and service. At the core of the Versatile RT490 is the revolutionary Rotating Concave Rotary System. A 360° concave wraps around a large rotor and counter-rotates. The counter rotation of the concave in relation to the rotor creates an unsurpassed threshing and separating area.
The new Versatile RT520 combine still features the unique rotating concave rotary system known for producing one of the cleanest samples in the industry. With more power for 2018, the RT520 also features a much larger cab and improved operator environment with a simple and ergonomic control console. For 2018, the RT520 receives a bump in horsepower and a new Tier 4 final QSG Cummins engine, offering power and efficiency. Other new features include an LED lighting package with more than twice the illumination of previous models.
