Robustness and stability designed for intensive use

The GA 8030 twin rotor rake delivers swaths to the side. Grass is raked across a width of 7.30 m to 8.30 m. They are ideal for intensive operations thanks to their MASTERDRIVE GIII gearbox

GA 8030 semi-mounted rakes are designed to be robust and stable for working in the field and travelling on the road. With working widths from 7.30 to 8.30 m and MASTER DRIVE GIII rotor drive, these two rakes are made for working in difficult conditions.
You can control the volume of crop in the swath with these side delivery rakes: rake individual swaths or combine two passes to form one swath. You can also adjust the working width to produce the best swath size possible. Result: output per hectare from the following baling and harvesting equipment is optimised. With this model, either one or two separate swaths can be delivered. You will appreciate this versatility when turning two swaths simultaneously for quicker drying and for more efficient raking at night. Delivering two swaths also accelerates the drying process of heavy forage.

MASTERDRIVE GIII gearbox on GA 1030 series

MASTER DRIVE GIII gearbox: reliable and wear-resistant

Agricultural machines have to withstand increasing amounts of pressure and larger working areas today. The reliability and longevity of machines is key to meeting the demands of farmers and satisfying their output needs. MASTER DRIVE GIII gearboxes are fully enclosed. Result: total protection of drive parts and less subject to wear. Their design ensures exceptional reliability and longevity, even under intensive use.
The GA 8030 is equipped with the MASTER DRIVE rotor which is well known for its reliable design and exceptional longevity, even when used intensively.
It includes a double reduction gearbox system with a bevel gear and a cylindrical gear. Bevel reduction tolerances are tightly controlled making the system extremely reliable and robust, even in difficult conditions.
Gearbox wear is greatly reduced and no maintenance is required. The double reduction gearbox system makes it possible to include larger cylindrical gears with more teeth for better power transmission.

Robust attachments

The MASTER DRIVE GIII gearbox has been designed to cope with ever increasing stress on the drive chain mainly due to: Increasing working widths and rotor diameters, raking difficult crops such as silage, haylage, straw and hay.
  • Important components have been strengthened to make the rotors lighter yet more robust:
  • Aluminium housings.
  • Optimised cam track to reduce forces on the roller.
  • Larger diameter roller to reduce rotation speed and pressure on the cam.
  • Tine arms with large-diameter bearings.
  • Stronger pivoting-tine-arm shaft.
  • Reinforced main shaft.
  • Reinforced mount of tine arms on tine holders (bolted).
  • Aluminium housings

    Top quality forage

    A well formed swath thanks to double-curved tine arms

    Optimum swath formation with double-curved tine arms

    The homogeneous quality and the volume of swaths are necessairy for faster drying and easy pick-up by balers.
    The tine arms on GA rakes are in a 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 swaths. Raking is of high quality even at fast speeds because the forage is not pushed past the swath.
    The advantages of double-curved arms:
    • They reduce the distance between tine passes. Forage loss is reduced, even at higher 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 subjected to stress.

    Protecting plant stubble

    Perfect rotor adaption to the variations in the field is just as important as reduced ground pressure when it comes to protecting the ground and plant stubble.
    GA 8030 side delivery rakes are fully equipped to meet these requirements:
    • The rotors are suspended at the junction of a pivot point and are independent from the main frame so they can pivot in every direction. 3D pendulum-type rotors follow uneven ground with precision, and to perfection. Up and downward movements have an impressive range from around +25 cm to -30 cm. Result: impeccable performance with the guarantee of clean forage and healthy stubble.
    • Each rotor is equipped with four wheels in tandem positioned extremely close to the rotor for optimised contour following on uneven plots.
    3D ground adaptation

    Pass over the swaths without damaging them

    51 cm clearance in one swath delivery mode and a remarkable 75 cm in two swath delivery mode clearly shows the advantage of the STABILIFT system for already rakes swaths.

    STABILIFT: mechanical and hydraulic rotor locking in transport mode

    STABILIFT: transport safety

    The 3D rotor suspensions are equipped with an integrated hydraulic cylinder which locks rotor movements automatically when it is raised from the ground.
    Main advantages of the STABILIFT system:
    • Sward protection as the tines don't scrape the ground when the rotors are lowered.
    • More stability due to the machine's lower centre of gravity.
    • Higher ground clearance for improved swath protection.
    • Quicker rotor lift.

    STABIDRIVE: stability on bends

    A small detail that makes a big difference to safety on the road. The axis of rotation of the coupling point between the tractor's lower link and the rake is not vertical, but slightly inclined. This increases pressure on the drawbar and the rear inner wheel. STABIDRIVE improves machine stability on the road, on bends and on slopes.

    GA 8030: select according to your needs

    Hydraulic control of the swath width is standard.
    Choose control box KGA 01L or KGA 11L to manage the following functions:
    • Changing from work to transport position and vice versa.
    • Selecting delivery type (one or two swaths).
    • Adjusting the swath width. 
    The KGA 11L features an additional function for raking height adjustment from the cab.

    GA 6930/7530: machines customizable with various options

    Customise your machine with many optional equipment tailored to your farm's needs:
    • you can deliver your forage on 1 or 2 windrows as required (2 windrow delivery as optional equipment on GA 6930).
    • Hydraulically adjust their widths with the windrow curtain to meet the requirements of the silage harvesters or balers that will follow.
    • Enjoy the individual hydraulic adjustment of the rotor height.
    • Enjoy individual lift of the front and rear rotors
    • Adopt the KGA 03L case to drive these functions.
    • Line The rear windrow curtain can be hydraulically adjusted to allow you to obtain a regular, well calibrated windrow.
    • A second windrow curtain can also be installed on the front rotor to work in two windrow mode.
    • '#NewLine
    • Reduce ground compaction with wide wheels.
    • The choice of the bogie axle with six wheels closest to the ties on the rear rotor ensures optimal ground following.
    Simple and practical to use, it is perfectly suited to the needs of medium and large farms. Don't choose when purchasing: with this machine, work in one or two windrows according to your needs!
