Features

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.

Heavy-Duty Components for Long Service Life

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
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 & Stability

3D Suspension
Four wheels on each rotor are positioned close to the tines and 3D suspension allows superior ground adaptation of the rotors on the GA 8731 for better raking. The four wheels also provide more stable operation in rough fields. For even more stability and greater ground adaptation, six wheels per rotor are standard on the GA 9531. An additional tandem axle is also available on the GA 8731 to bring the standard wheels per rotor from four wheels to six.

Low Transport Height
A practical plus of the GA 8731 is that transport remains low without having to remove any tine arms. This makes traveling from one field to the next more efficient. GA 8731 transport height is 13’1” without the removal of tine arms. GA 9531 transport height is 14’6” without the removal of tine arms 12’6” with tine arms removed.

Locked Rotors – For Transport
The rotors are locked hydraulically and mechanically in their transport position. This considerably increase the machine’s stability during transport, even on poorly maintained roads.

Easily Make Adjustments for Your Rake

Electric Control Boxes
The GA 8731 and GA 9531 come with the KGA 02C control box as standard equipment. The box allows the operator to easily switch from field and transport modes, set windrow width and optionally lift each rotor individually. The KGA 11C control box is available as an option to also enable individual, or linked hydraulic rotor height adjustment. The GA 8131 offers the optional KGA 01S control box to enable individual rotor lift or individual rotor height adjustment from the tractor cab.

Simple Height Adjustment
All you need is a hand crank to manually change the rotor height. A standard gauge on the machine makes accurate adjustment easy. Hydraulic height adjustment is available as an option on both models with the KGA 11C control box.

Windrow Width Adjustments
The windrow width is also easy to adjust. Working width is easily adjusted on the control box from the tractor seat to adapt to varying conditions or harvesting equipment.

Optional Independent Rotor Lift
With the optional independent rotor lift, rotors can be lifted individually where clearance of more than 29” is possible. You will no longer have to worry about disturbing windrows when you pass over them.
