Proven, Reliable Components that Help in Heavy or Dense Crops
Masterdrive® GIII Gearbox
The patented KUHN Masterdrive GIII double-reduction gearbox is designed for heavy crops, tough field conditions, and intensive use. Key components have been improved to build lighter, yet stronger rotors such as: aluminum alloy housings, optimized cam track minimizing force on the follower bearing, larger follower bearing diameter reducing rotation speed and pressure on the cam, tine arms with large-dimension bearings, sturdier pivoting tine support shaft, reinforced main shaft, and reinforced mounting of tine arms on tine holders. The Masterdrive GIII’s ability to move heavy wet crop, handle dry hay gently, and neatly windrow corn stalks is unrivaled in the industry.
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.
Stable & Versatile Design
Resting firmly on extra-large undercarriages and fitted with up to six wheels per rotor, the three models can easily perform in varying field and crop conditions.
Easy Adjustments to Meet Your Raking Needs
One to Two Windrows
In addition to the side delivery of one windrow, these rakes can be set to form two separate windrows. This is particularly useful in carrying out tasks to speed up the drying process such as turning windrows and forming narrow windrows in heavy crop conditions
Hydraulic Windrow Width Adjustment
A hydraulic cylinder allows the operator to easily adjust windrow width from the cab. This system also folds the curtain assembly for transport position, eliminating cumbersome manual work. A second, manually controlled front curtain for forming two windrows is standard on the GA 6632, 7932 and 9032.
Narrow for Transport and Storage
These rakes can be easily changed from work to transport position from the tractor cab. The width is reduced to 9’10” for GA 6632, 11’6” for GA 7932 and 13’5” for GA 9032. In addition, these three models feature removable arms to further reduce transport width by 3’ or more for driving comfort and increased safety for long transport distances. This is also helpful in difficult to access locations or storage areas.
Excellent Ground Adaptation & Clearance
The pivot points, located on the chassis, allow both rotors to follow ground contours independently. The rear rotor additionally operates as standard with a 3D suspension for even less crop contamination.
Tandem axles are standard on both rotors on all models. They run especially smooth on rough roads, but also over uneven grassland (for example due to damage caused by wildlife or after use as pasture). The rear rotors of all models are also equipped with two additional wheels. A dampener axle is an option on the front rotor of the GA 6632 and 7932 for additional support. An optional prop wheel can be fitted to the front rotor to provide smoother operation in very rough conditions.
Parallelogram-Type Drawbar Hitch
A parallelogram-type drawbar hitch allows a high implement lift height with a solid secure hitch as the front part of the drawbar always stays horizontal. A drawbar mounted jack stand is included for easy attachment to the tractor.
