KUHN GA 8131, 8731 and 9531 twin-rotor, center-delivery rotary rakes gently handle high volumes of hay and efficiently move it into high-quality windrows. They have the ability to move both wet and dry crops alike, while keeping your productivity high and maintenance requirements low. These semi-mounted rakes are known for their superior ground adaptation, durability and reliability, thanks to the Masterdrive® GIII gearbox. This KUHN-patented double reduction gearbox is the most reliable, heavy-duty gearbox available in the industry. 3D rotor articulation helps the rakes adapt quickly to varying field conditions, while the double-curved tine arms gently handle the crop and allow you to operate at higher working speeds. Working widths, ranging from 23’4” to 30’6” depending on the model, can easily be adjusted from the comfort of your tractor seat.
