GA Gyrorakes Trailed Single Rotor GA 4220 TH and GA 4221 GTH G r a s s H a r v e s t i n G at i t s b e s t ! GA Trailed Gyrorakes GA 4220 TH and GA 4221 GTH New HIGH-CAPACITY SINGLe-ROTOR MOdeLS the Ga 4220 tH and Ga 4221 GtH Gyrorakes are designed to meet the needs of hay producers who demand improved productivity while increasing the quality of their hay and forage crops. long, flexible tines touch the crop just once, lifting and depositing it neatly into the windrow.

this gentle raking action ensures that the leaves remain intact. the large, well-formed windrows promote faster drying, enabling producers to harvest crops at their peak nutritional value with less reliance on the weather. since the tines do not normally contact the soil, there is less opportunity for contaminants to enter the windrow, resulting in higher quality forage. Reduced Transport Width the Ga 4221 GtH provides a transport width and storage requirement of just 6′ 5 “. the guards and swath curtain are easily folded, while detachable tine arms can be conveniently stowed for transport. exCLuSIve MASTeRdRIve® GeARbOx Benefits you expect from KUHN the new rotor design, with eleven tine arms, provides cleaner raking, a 10% increase in capacity and faster working speeds compared to previous models. exclusive double-curved tine arms optimize the tine position, providing superior raking quality and windrow formation. Complicated cam-track adjustments that are common on less advanced rotary rakes are eliminated. the exclusive Masterdrive® doublereduction gearbox provides unsurpassed reliability. the design allows right-hand swath delivery, which makes the rake easier and more convenient to operate with standard right-side tractor controls. Get quality and reliability from the pioneer and world’s leading manufacturer of rotary rakes, along with outstanding support and maximum resale value. Exclusive Swath Curtain Adjustment a parallelogram linkage simultaneously moves the swath curtain to the rear as it is extended. this improves windrow formation and placement by ensuring that the curtain is always in the proper relationship to the crop. Standard Bogie Axles bogie axles allow for higher speeds and smoother operation over rough and irregular terrain. they help the tines follow the ground precisely, for clean raking and less risk of contaminants in the hay. High Clearance Lift the dual-point hydraulic lift raises the rotor evenly, providing extra-high clearance to cross over windrows or when moving between fields. Grass Harvesting at its Best!
