The single-rotor KUHN GA 4731 T and 5031 T trailed rotary rakes are simple, user friendly and can be operated by a lower horsepower tractor. They provide excellent raking quality and an even swath width in the most uneven of fields. Rakes are fitted with rotors featuring KUHN’s patented Masterdrive® GIII double-reduction gearbox that has been tested in the heaviest of forages. Ground following is perfect in the hilliest conditions because of the tandem axles and the wheels being placed closely to the tines, keeping them engaged in the hay and out of the ground. The height is easy to set with a crank handle. These machines were designed with three things in mind: simplicity, reliability and longevity.

Proven and Durable Components for Optimum Raking Performance


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.
