Features

Hydraulic Power

The hydraulic unit of the GA 13131 and 15131 is mounted on the pivoting headstock of the machine frame. In this way the primary drive shaft is always perfectly aligned to the tractor, even in tight corners. Moreover, you can adapt the PTO speed from the cab according to type and volume of forage. The hydraulic drive considerably simplifies the machine and provides multiple solutions for improved work.

Masterdrive® GIII Gearbox

The Masterdrive gearbox reveals an exclusively designed drive using spur gears. The rotor gear wheels are driven by the latter. In this way, tolerances are tightly controlled. This enhances the robustness of the whole assembly in difficult conditions. With the hydraulically driven and better performing Masterdrive GII gearbox, the GA 13131 and 15131 four-rotor rotary rake is well prepared for high volumes of difficult crop.

Boost Function

From the tractor cab, the rotation speed of the front rotors can be increased by 20% compared to the rear rotors. With the help of this boost function, the forage is ejected further and with more drive toward the center of the machine. This leads to the forage becoming less twisted as it is not rolled over the ground, allowing the rear rotors to form a uniform and airy windrow. This is ideal for perfecting the forage drying process.

Smart Headland Management

For easy and efficient headland turns at the end of the field, an automated pre-programmed headland sequence has been integrated into the VT 50 control box. It can be simply adapted to specific needs, and thanks to angle sensors, the rotors will always be raised to the pre-defined height regardless of working width.

Adjustable Working Width

With wide working widths, high field output is one, but not the only bonus of the GA 13131 and 15131 rotary rakes. These large widths significantly increase the demand for a machine’s ability to adapt to the subsequent harvester. That is why it is possible to fully adjust the working and windrow widths continuously and hydraulically from the tractor seat.
