The Kuhn GA 8731 twin-rotor, center-delivery rotary rake gently handles high volumes of hay and efficiently moves it into high-quality windrows. It has the ability to move both wet and dry crops alike, while keeping your productivity high and maintenance requirements low. A working width of 25’3” to 28’2” can easily be adjusted from the tractor seat.

This semi-mounted rake is known for its superior ground adaptation, durability and reliability. It features the new MasterDrive® GIII gearbox, a Kuhn-patented double reduction gearbox, which is the most reliable, heavy-duty gearbox available in the industry. 3D rotor articulation helps you adapt quickly to varying field conditions. The double-curved tangential tine arms gently handle the crop and allow you to operate at higher working speeds. Working width and raking height are easily adjustable.
