Designed for Intensive Use
Masterdrive® GIII Rotor
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.
Superior Ground Adaptation & Transportability
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.
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. (Tine arm removal not possible on GA 4230 T). Lights are available as an option on these machines.
The rotor wheels on KUHN rotary rakes are positioned extremely close to the tines. This allows the tines to follow ground contours minimizing contact with the ground to avoid incorporating impurities into the windrow.
Operator Efficiency and Comfort
For maximum 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.
Hydraulic Lift and Height Crank
The GA 4230 T and GA 4231 T come with a standard hydraulic raise/lower function for headland turning. The working height stop is adjusted by a simple hand crank, making any adjustments to field conditions quick and easy. A cylinder on the tongue ensures the rake lowers rear first similar to a plane touching down, this ensures the tines do not contact the ground when raking.
Swath Curtain Adjustment
The swath curtain is easily adjusted by sliding the support tube and inserting a pin to lock it in place. Making it quick to adjust windrow width for varying crops to minimize drying time.
The right guard and windrow deflector can be easily raised and lowered with the assistance of the convenient spring design.
