2020 Kuhn North America GA Series 9531

You will appreciate the increased comfort of the KUHN GA 8131, 8731 and 9531 with their minimum maintenance, easy adjustments and increased stability during transport, especially while turning or on slopes. Working widths range from 23’4” to 30’6”.

KUHN GA 8131, 8731 and 9531 twin-rotor, center-delivery rotary rakes gently handle high volumes of hay and efficiently move it into high-quality windrows. They have the ability to move both wet and dry crops alike, while keeping your productivity high and maintenance requirements low. These semi-mounted rakes are known for their superior ground adaptation, durability and reliability, thanks to the Masterdrive® GIII gearbox. This KUHN-patented double reduction gearbox is the most reliable, heavy-duty gearbox available in the industry. 3D rotor articulation helps the rakes adapt quickly to varying field conditions, while the double-curved tine arms gently handle the crop and allow you to operate at higher working speeds. Working widths, ranging from 23’4” to 30’6” depending on the model, can easily be adjusted from the comfort of your tractor seat.

Masterdrive® 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 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.
