The new KUHN GA 4230 T and GA 4231 T single-rotor rotary rakes build on the popularity of the prior generation of KUHN’s single-rotor rakes with the incorporation of the Masterdrive® GIII double-reduction gearbox. The main gearbox features the KUHN exclusive double reduction drive that not only provides the ergonomic benefits of right hand swath delivery, but also improves the power flow through the gearbox. These new models have a lighter, but stronger construction with aluminum rake arm housings, large cam bearings and a cam track designed to reduce peak loads. They maintain the KUHN double bend tine arms that offer clean raking and excellent capacity for consistent, fluffy windrows. The GA 4230 T has fixed tine arms, for operations where transport is a concern, the GA 4231 T has easily removable tine arms that can be stored on the hitch to achieve a transport width of 6’5″ (1.95 m).
Designed for Intensive Use
Masterdrive® GIII Rotor
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.
