Go for a mounted twin rotor rake rather than single rotor!

GA 6501 P mounted twin rotor rakes deliver central swaths between 5.65 m and 6.40 m. Their raking quality is impressive and they produce perfect swaths for fast dry-down.

Single rotor rakes are pushed to their limits on farms with continuously increasing grassland areas. That's why a twin rotor machine with higher output and just as compact as a single rotor rake is exactly what you need. GA 6501 P mounted twin rotor rakes are your best choice with no compromise made on manageability.
They have double-curved hyper-tangential mounted tine arms that produce high-quality raking and perfect swath formation for fast forage drying. These rakes include all the features of a professional rake while being great value for money and highly manoeuvrable.

Compactness and manoeuvrability are the watchwords

Respect of road dimensions

Easy to use, the GA 6501 P and GA 7631 P can be easily handled even by the least experienced users.
The transition from working to transport position is made hydraulically from the cab, without having to remove the rotor arms, saving time between plots.
During transport, the dimensions of the machines create a compact unit, which has the advantage to facilitate and secure movement on narrow roads or in urban areas.
Thanks to their compactness and manoeuvrability, these mounted models also allow access to small plots and narrow entrances.

Compact storage compared to trailed models

You save storage space in your sheds with the narrower storage area from mounted twin rotor rakes. The machines can be stored vertically supported by its special parking stands.

Great raking for clean forage, free of impurities

A well formed swath thanks to double-curved tine arms

Swath formation: the benefit of double-curved arms

The homogeneous quality and volume of windrows are conditions for fast drying and easy pick-up by balers.
The tine arms on GA rakes are in hyper-tangential position. This means that they reach a 90¡ angle very late. With the tines' sharp-angled cam, tine clearance is quick, later and requires little rotational effort to produce regular, fluffy and straight windrows. Raking is of high quality even at high speeds because the forage is not pushed past the windrow.
The advantages of double-curved arms:

They reduce the distance between tine passes. Forage loss is reduced to a minimum, even at high speeds.
The main weight is at the centre of the tine arm. This increases service life as it is not subject to pressure during rotation and the guide rollers are less subject to stress.

Rotors designed to reduce impurities

To protect the soil and the vegetation cover, a perfect rotor adaptation to variations in the field is just as important as reduced ground pressure to limit compaction. Central rakes are fully equipped to meet these requirements.
The rotors can pivot in all directions thanks to the 3D rotor suspension system. They follow variations in the field precisely and efficiently. Result: flawless performance, ensuring clean forage and healthy vegetation cover.
Each rotor is equipped with four wheels positioned close to the tines for optimised ground contouring and excellent responsiveness.
These features prevent impurities from contaminating the forage.

GA 7631 P: the MASTERDRIVE GIII gearbox is a guarantee of reliability

Farm machinery must work more and more hectares and withstand ever higher forces. Machine reliability and durability are the key to meet the requirements of users in terms of work output.
The MASTERDRIVE GIII geaorboxes have been developed to remain closed. The drive components thus are fully protected and the wear resistance is improved. This design ensures exceptional reliability and durability even for intensive use.
This way, the rotors offer excellent performance while reducing the introduction of impurities into the fodder, preserving its quality.

Easy adjustments for great versatility

GA 6501 P: swath width adjustment via a crank handle

A swath width up to 2.20 m

To adapt to different harvesting machines and types of forage, the mounted twin rotor rakes feature the adjustment of the working width.
On the GA 6501 P, the adjustment is made using the crank handle to achieve a windrow width up to 2.00 m.
On the GA 7631 P, the hydraulic setting of the working width is included as standard. The machine can thus create windrows from 1.30 to 2.20 m.

Simple adjustment of working height

In order to preserve the vegetation cover, the working height can be adjusted on both models of mounted rake. This adjustment is centralised in the centre of the rotor on the GA 6501 P and is made using a crank handle on the GA 7631 P.
As an option, the raking height can also be adjusted hydraulically on the GA 7631 P to suit all requirements.

GA 7631 P: optional equipment for an individual lift of the rotors

The GA 7631 P mounted twin rotor rake feature an additional optional adjustment: the individual lift of the rotors. This allows to work with only one side of the machine while the opposite side remains in swath passing mode. This system is useful to avoid passing over swath that have already been formed.
The control is simple: preselect the rotor before activating the tractor's control valve.
