Travel with ease on roads or when entering narrow fields with the GA 6501 and 7501 + thanks to:
The homogeneous quality and volume of the swath are conditions for fast drying and easy pick-up by the following baler.
The tine arms on GA rakes are in hyper-tangential position. This means that they reach a 90 degree 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 swaths. Raking is of high quality even at high speeds because the forage is not pushed past the swath.
The advantages of double-curved arms:
The rotors are capable of gently contouring uneven ground without damaging grass stubble. They are equipped with a highly effective 3D rotor suspension system.
The rotor wheels are positioned close to the tines to provide optimised ground contouring on uneven plots. These features prevent impurities from contaminating the forage.
1001 series rakes are equipped with 3D bogie axles.
The bogie axle is available for tough fields, as an option on GA 7501 + model. It is ideal for rotor guidance in difficult conditions (ruts, rough grassland….) and at high groundspeeds
Swath width can be easily adapted – it can be adjusted to up to 2.00 m via a crank handle.
The swath width is adjusted with a 4-position handle.
In standard configuration with a working width of 6.90 m to 7.40 m, the swaths width is between 1.30 m and 1.90 m. The machine can be configured in a narrow version for a reduced working width of 6.70 to 7.20 m and a reduced swath width. This configuration also meets the requirements of road constraints with a transport height of 4 m without disassembling the tine arms.
