PROVEN AND DURABLE COMPONENTS

Proven and Durable Components to Assist You with Raking

Masterdrive® Gearbox

The KUHN exclusive Masterdrive double-reduction gearbox is designed for all types of crops, larger rotors, and demanding conditions. The fully enclosed Masterdrive double-reduction gearbox incorporates a two-stage reduction drive for increased durability and reliability with a longer service life and lower power requirement. The large gears and gear teeth are meshed together with tight clearances to minimize wear and provide the best overall power transmission for maximum efficiency.

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

Maximum Operator Efficiency and Comfort

Right-Hand Delivery

For maximum operator efficiency and comfort, right-hand delivery is ideal. All KUHN single-rotor rakes above a 13’ working width feature right-hand delivery as standard due to the double-reduction Masterdrive® gearbox. You can monitor raking quality and make adjustments at the same time with both the windrow and tractor controls conveniently located 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. (Tine arm removal not possible on GA 4220 TH)

Spring Design

The right guard and windrow deflector can be easily raised and lowered with the assistance of the convenient spring design.

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 the curtain is always in the proper position relative to the crop.

SUPERIOR GROUND ADAPTATION

Tandem Axles

Equipped with standard tandem axles, GA trailed rotary rakes are designed to handle uneven ground. They smooth out bumps and holes keeping the distance between the ground and tines constant. The close positioning of the wheels to the tines provides smooth operation.

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.

Second Dampener

GA 4321 GM mounted models are available with an optional second dampener. This will allow these models to run more smoothly over bumpy and hilly fields.
