The 100% Hydraulically Driven Rake!

The uniform windrows they create provide a base for a high-performance harvesting chain.

KUHN GA 13131 and GA 15131 quad-rotor rotary rakes not only stand for high work rates, but also combine high flexibility and superior quality of work. The uniform windrows they create provide the base for a high-performance harvesting chain. Despite their impressive size, KUHN four-rotor rotary rakes are easy to operate and adjust. All settings are made hydraulically from the tractor seat utilizing an ISOBUS monitor.

Features may include:

Masterdrive® GIII 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

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.

3D Suspension

Suspended on an articulation joint and independent from the main frame, the rotors can pivot in all directions allowing close ground following over undulating terrain. The tines collect the crop with the greatest precision.

Jet Effect

A hydraulic cylinder at the front of the rotor head controls the “touchdown” when lowering the rotor. In a similar way to an airplane, the rear touches first with the front following. This ensures that the tines to do not contact the soil.
