Kuhn GA 4230 T & GA 4231 T The Rake You Love with Added Reliability and Durability

Single-rotor, trailed KUHN GA 4230 and 4231 T rotary rakes, with working widths of 13’10” are designed for ease of operation and long life.

The new KUHN GA 4230 T and GA 4231 T single-rotor rotary rakes build on the popularity of the prior generation of KUHN’s single-rotor rakes with the incorporation of the Masterdrive® GIII double-reduction gearbox. The main gearbox features the KUHN exclusive double reduction drive that not only provides the ergonomic benefits of right hand swath delivery, but also improves the power flow through the gearbox. These new models have a lighter, but stronger construction with aluminum rake arm housings, large cam bearings and a cam track designed to reduce peak loads. They maintain the KUHN double bend tine arms that offer clean raking and excellent capacity for consistent, fluffy windrows. The GA 4230 T has fixed tine arms, for operations where transport is a concern, the GA 4231 T has easily removable tine arms that can be stored on the hitch to achieve a transport width of 6'5" (1.95 m).

your benefits

Designed for Intensive Use

Kuhn GA 4230 T & GA 4231 T 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.

Kuhn GA 4230 T & GA 4231 T 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 & Transportability

Kuhn GA 4230 T & GA 4231 T Tandem Axles

Equipped with standard tandem axles, GA trailed rotary rakes are designed to handle uneven ground. They smooth out bumps and holes keeping the distance between the ground and tines constant. The close positioning of the wheels to the tines provides smooth operation.

Kuhn GA 4230 T & GA 4231 T Narrow Transport Width

Road transport can be accomplished with complete peace of mind – simply store the tine arms in the convenient rack at the front of the machine and fold up the guards vertically. (Tine arm removal not possible on GA 4230 T). Lights are available as an option on these machines.

Kuhn GA 4230 T & GA 4231 T Rotor Wheels

The rotor wheels on KUHN rotary rakes are positioned extremely close to the tines. This allows the tines to follow ground contours minimizing contact with the ground to avoid incorporating impurities into the windrow.

Operator Efficiency and Comfort

Kuhn GA 4230 T & GA 4231 T Right-Hand Delivery

 For maximum efficiency and comfort, right-hand delivery is ideal. All KUHN single-rotor rakes above a 13’ working width, feature right-hand delivery as standard due to the double-reduction Masterdrive® gearbox. You can monitor raking quality and make adjustments at the same time with both the windrow and tractor controls conveniently located on the right side.

Kuhn GA 4230 T & GA 4231 T Hydraulic Lift and Height Crank

The GA 4230 T and GA 4231 T come with a standard hydraulic raise/lower function for headland turning. The working height stop is adjusted by a simple hand crank, making any adjustments to field conditions quick and easy. A cylinder on the tongue ensures the rake lowers rear first similar to a plane touching down, this ensures the tines do not contact the ground when raking.

Kuhn GA 4230 T & GA 4231 T Swath Curtain Adjustment

The swath curtain is easily adjusted by sliding the support tube and inserting a pin to lock it in place. Making it quick to adjust windrow width for varying crops to minimize drying time.

Kuhn GA 4230 T & GA 4231 T Spring Design

The right guard and windrow deflector can be easily raised and lowered with the assistance of the convenient spring design.
