OPTIMUM RAKING PERFORMANCE

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.

SUPERIOR GROUND ADAPTATION

Superior Ground Adaptation & Transportability

Tandem Axles

When in hilly conditions, the GA 4731 T and GA 5031 T have solid stability with tandem axles and the added benefit of having cushioned suspension due to a shock absorber on the machine. Ground following is also ideal because of the proximity of the tandem axles and the wheels to the tines, keeping them engaged in the hay and off the ground.

High Ground Clearance

When raised in the headland position, there is 24” of clearance between the tines and ground to pass over previously made windrows without disturbing them.

Road Transport

With some rakes, switching between field and transport can be tedious. The GA 4731 T and 5031 T have been designed to include centralized arm holders and a quick locking system for easy transition in and out of the field. The optional hydraulic folding windrow curtain and guard makes the transition from working position to transport quick and easy.

EASY, TROUBLE-FREE ADJUSTMENTS

Working Height Adjustments

The adjustment setting for working height (1) and rotor leveling (2) is extremely easy to do with the crank handle on the machine. With this feature, you can precisely set the raking height in order to maximize the crop pickup while minimizing the collection of foreign material.

Adjustable Windrow Width

Set the desired windrow width with the easily adjustable windrow curtain to match up to any piece of harvesting equipment being used. Let the tines and the tine arms do the rest by gathering the crop and placing it in a well-formed, light and fluffy windrow.

One Single-Acting Hydraulic Valve

With a low horsepower requirement, an easy folding windrow curtain and one single-acting hydraulic valve to raise and lower the machine, these rakes are extremely easy to operate.
