Power transfer reinvented

The innovative, unique drive concept has been designed for tractors rated from 200 to 500 PS. This means that the JUMBO can be operated with a wide range of tractors.

The driveline has a double wide-angle PTO shaft without a clutch and is powered by a Powerband. Optimum power transmission to the rotor is ensured by angular/planetary gears in the rotor drive.

The Powerband delivers maximum power transfer in all operating conditions. It ensures smooth running and a damping effect in changing operating conditions. This protects the mechanics and reduces maintenance and wear costs to a minimum.

Special overload protection system

A PTO shaft with an overload protection system is subjected to extreme wear-intensive stress when used in high-performance harvesting equipment. The angling of the PTO shaft during operation produces torsional vibrations which prematurely trigger the overload protection system and negatively impact throughput.

PÖTTINGER therefore decided to remove the overload protection from the PTO shaft and integrate it directly in a fixed position in front of the angular/planetary gearbox.

Thanks to the newly developed drive concept the JUMBO can be continually operated at up to 3.000 Nm. The result is optimum protection of all drive components against unnecessary stress and wear-intensive blockages.

Irregular swaths can be picked up with no reduction in speed and no losses, even when cornering. This increases loading efficiency enormously.

Perfectly matched

In order to be able to optimise the JUMBO to the forage and the tractor power, a dynamometer bolt constantly monitors the torque applied to the drive train.

When this reaches the set maximum value, the scraper floor is activated. That is how the compaction of the forage by the rotor can be optimally adapted to the incoming forage volume and the power of the tractor.
