2025 Kuhn GA Quad-Rotor Rotary Rakes 15231

With impressive working widths, ranging from 27’7” to 48’3”, KUHN GA 13231 and GA 15231 quad-rotor rotary rakes offer the ultimate capacity.

KUHN's quad-rotor rotary rakes have the size and performance for even the most demanding operations. Working widths from 27' 7" to 48' 3" cover large areas quickly, while double-bent tine arms create fluffy windrows while gently handling crop, preserving nutrient content. KUHN's Masterdrive® GIII double-reduction gearbox's ability to move heavy wet crop, handle dry hay gently, and neatly windrow forage is unrivaled in the industry.

KUHN GA 13231 and GA 15231 quad-rotor rotary rakes reduce maintenance costs due to their comprehensive list of innovative features, including the hydraulic rotor drive. These rakes are easy to operate and adjust. All settings are made hydraulically from the tractor seat via the ISOBUS monitor.

Features may include:

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 forage is unrivaled in the industry.

Hyper-tangential, double-curved tine arms are designed to form fluffy and straight windrows for superior raking quality at higher 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.

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.

For easy and efficient headland turns at the end of the field, an automated pre-programmed headland sequence can be utilized on the ISOBUS monitor. The headland sequence can be adapted to specific needs and thanks to angle sensors, the rotors will always be raised to the pre-defined height regardless of working width. Once all pre-adjustments are done, you only need to press a button, then sit back and let the electronics do the work.

The working width is adjusted from the ISOBUS monitor, making this adjustment easy for the operator. The front rotors can be moved independently from the rear rotors to choose a desired working width. Then adjust your rear rotors to create a windrow width to best match your harvesting equipment.

The raking height is easily adjusted from the operator’s seat. This can be done simultaneously for the two front or the two rear rotors, as well as individually for each single one. The current height is indicated both on the terminal’s display and the rotor undercarriage.
