Whether raking hay or straw, the GA 8121 twin-rotor rotary rake effectively handles difficult conditions. Even in intense use, the Masterdrive® gearbox provides superior reliability and durability.
The KUHN GA 8121 semi-mounted rotary rake effectively handles difficult conditions whether raking hay or straw. Its compact design enables easy maneuvering in and out of hard-to-access fields.
3D rotor suspension allows the rotor to precisely follow field contours, providing the cleanest possible raking. Long flexible tines touch the crop just once, lifting and placing it neatly into the windrow. For crops such as alfalfa, this gentle handing, in conjunction with being able to rake when the hay is still damp, is especially beneficial as it ensures the leaves will remain intact. Fully enclosed, grease-filled Masterdrive® gearboxes have time-proven reliability and are practically maintenance free.
Features may include:Masterdrive® Gearbox
The KUHN exclusive Masterdrive double-reduction gearbox is designed for all types of crops, larger rotors, and demanding conditions. The fully enclosed Masterdrive double-reduction gearbox incorporates a two-stage reduction drive for increased durability and reliability with a longer service life and lower power requirement. The large gears and gear teeth are meshed together with tight clearances to minimize wear and provide the best overall power transmission for maximum efficiency.Double-Curved Tine Arms
Double-curved tine arms are designed to form fluffy and straight windrows for superior raking quality at high speeds. Fluffy windrows allow more air movement through the crop promoting fast and uniform drying!
KUHN rotary rakes achieve this by following two basic principles for ideal windrow formation. First, the tine arms maintain a positive forward position right up to the point where the forage is delivered to the windrow ensuring gentle crop handling and minimal ash incorporation. Second, a steep cam track allows the tines to be raised very quickly to provide additional clearance over the windrow.
