The KUHN GA 4201 and 4401 are built on the popularity of the prior generation of KUHN’s single-rotor rotary rakes. The rakes were redesigned with a focus on smaller tractor sizes, with special consideration to ensure a limited machine weight and enhanced ergonomics. Large, well-formed windrows promote faster drying, enabling producers to harvest crops at their peak nutritional value with less reliance on the weather.

The pivoting headstock ensures maneuverability, improved terrain following, raking quality and consistent windrow shape. Hyper-tangential, double-curved tine arms allow these rakes to work at various speeds, while still gently raking, assuring raking quality. Since the tines do not normally contact the soil, there is less opportunity for contaminants to enter the windrow.

YOUR BENEFITS

Proven and Durable Components to Assist You with Raking

Pivoting Headstock

The updated pivoting headstock allows a greater turning angle of 48 degrees to maneuver in tight field corners. Machine shifting and swinging is also reduced, protecting crop stubble. The headstock stabilizers also improve performance during turns and while working on slopes.

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.

Maximum Operator Efficiency and Comfort

Right-Hand Delivery

For maximum operator efficiency and comfort, right-hand delivery is ideal. The GA 4201 and 4401 feature right-hand delivery as standard. Operators can monitor raking quality and make adjustments at the same time with the tractor controls conveniently located and commonly found on the right side.

Narrow Transport Width

Road transport can be accomplished with complete peace of mind – simply store the tine arms in the convenient rack at the front of the machine and fold up the guards vertically. Lighting and turn signals are also standard for maximum safety.

Raking Height Adjustment

Easy adjustments to the rake height are completed using a crank accessible from the tractor cab. The rake height mechanism allows for adjustments, even when the whole weight of the rake is supported by the rotor wheels.

Windrow Curtain Adjustment

The simplified windrow curtain adjustment sliding tube creates quick and easy adjustments to the windrow width.

Superior Ground Adaptation

Tandem Axles

Optional tandem axles are designed to handle uneven ground. They smooth out bumps and holes, keeping the distance between the ground and tines constant.

Prop Wheel

All mounted KUHN rotary rakes can be fitted with an additional prop wheel at the front of the rotor. This additional wheel provides improved raking performance and enhanced following of changing ground contours.

Wheel and Tine Proximity

Wheels are positioned close to the tines, allowing for quick machine reaction to changes in terrain, reducing ash contamination and maintaining forage quality. This also minimizes the risk of possible damage from tines striking the ground.
