GA 8121



The Kuhn GA 8121 semi-mounted rotary rake effectively handles difficult conditions whether raking hay or straw. Compactness is a major asset, especially when maneuvering in and out of hard-to-access fields. This model is well suited for farm operations that bale large quantities of dry hay and are looking for larger working widths of 24' 3" to 26' 3".

The central-delivery rake design creates ideal windrows for round or large square balers, with windrow width adjustments from 4' 7" to 6' 7" to perfectly match the baler pickup heads. 3D rotor articulation allows the rotor to precisely follow field contours, providing the cleanest possible raking. The tricycle undercarriage has four wheels that are located as close to the tines as possible, ensuring accurate tine-height control around the raking circumference. Each tine reacts to changes in the field surface more quickly and with greater precision than traditional 2D bogie-axle undercarriage systems. Fully enclosed, grease-filled Masterdrive® gearboxes have time-proven reliability and are practically maintenance free. With a rotary rake concept, superior raking quality is attained through gentle, clean raking at varied speeds, allowing faster operation and drying time.
