KUHN GA 8030 and 9030 semi-mounted, twin-rotor rotary rakes are designed for intensive use and simple operation. These side-delivery models excel in a variety of applications, such as managing crop densities, and choosing between one or two windrows. During heavy first cut or light fourth cut, you can control the volume of crop in the windrow. Rake individual swaths or combine the crop from two passes to form one windrow. Simply adjust the working width to produce the best windrow size for your operation. You will particularly appreciate the versatility of one or two windrows, with the GA 8030, when wanting to turn two windrows simultaneously or produce night windrows quickly to reduce dew on the crop.

 

KUHN GA 8030 and 9030 rotary rakes include important innovative features for your benefit. One of these features is the Stabilift™ suspension, an exclusive design lifts the rotors and locks them in slightly inclined position for time savings, high ground clearance and hydraulic locking during transport. Other design features include the StabiDrive™ and heavy-duty Masterdrive® GIII gearbox. These semi-mounted models have excellent tracking and stability on uneven ground, great maneuverability, reduced dimensions in transport position and easy adjustments.

Heavy-Duty Components for Long Service Life

GA_MasterdriveGIIIGearbox.png

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.

Exceptional Ground Adaptation

3D Suspension

The 3D suspension of the rotors provides exceptional adaptation of the machine to the terrain. Up and down movements show an impressive range from +10” to -12”.

Stabilift™ 3D Suspension Lock

Both 3D suspension rotors are equipped with an integrated hydraulic cylinder, which locks the rotor movement automatically as soon as a rotor is lifted from the ground. The main advantages of this system include:

  • Lower the machine’s center of gravity for more stability
  • Higher ground clearance for windrow

StabiDrive®

The ultimate stability in turns. It’s the small details that make a big difference for safe travel on the road: The axis rotation of the coupling point between the tractor’s lower links and the rake is not standard vertical, but rather slightly inclined forward. This results in the center of gravity being more in the center of the rake when turning which significantly increases stability, especially in hilly conditions. This increases the pressure on the outer lower link as well as the inner wheel of the rake’s undercarriage.

Electric Control Boxes to Simplify Your Life

GA_SideDelivery_ControlBoxes.png

Electric Control Boxes

For easier, more convenient use, the GA 8030 and 9030 come with the choice between two control boxes.

Both boxes control the following functions:

  • Changing from working to transport position
  • Selection of delivering one or two windrows (GA 8030 only)
  • Windrow width adjustment
Additional features available with the KGA 11L premium box:

  • Hydraulic working height adjustment of the rotors
KGA 02L is standard on the GA 8030. KGA 11L is standard on the GA 9030, optional on the GA 8030.
