More output and durability is the thinking behind the re-engineered Quadrant big square baler from Claas.

Look out for the new HD pick-up in what is Germany’s top-selling square baler. For the 2022 product year, the 5000 and 4200 series have been given a comprehensive technical upgrade, along with the additional designation Evolution.

This pick-up comes with two cam tracks for maximum torsional resistance and exceptional robustness, said Claas, which added that wear costs had been reduced by increasing the use of highly resilient components borrowed from the Claas Jaguar forager pick-up and by reworking and strengthening bearings, intake panels and other parts.

Mechanically driven, the pick-up has five rows of tines and 18 double tines per row that means the extra row of tines allows the pick-up to rotate more slowly, while the speed of the spring-mounted power feeding system (PFS) roller has been increased. The feed roller has also been given extra paddles which can be removed when harvesting long-stalked crops.

To handle the higher throughput volumes from the pick-up, the diameter of its main drive shaft has been enlarged and has semi-automatic chain tensioning and automatic lubrication.

The bale chamber has also been changed, having been redesigned and strengthened to produce a better bale shape and slightly higher bale density. Factory-fitted sides knives and deflectors reduce material build-up in the ram guide area when baling – further increasing operational safety and reducing cleaning effort. The knives also help to produce a smooth side to the bale removing the impression left by the ram bearing channel.

The speed of response of the automatic baling pressure control (APC) has also been increased and it is also more sensitive to twine tension or load in the intake area.

There's also a completely new front frame and headstock, which provides additional hitching positions for drawbar eyes or K80.

Modifications to the twine boxes also make life easier for operators, The twine guide swings out and can be locked in position so that the twine can be threaded when standing beside machine without having to stretch.

There's a new optional function that means the bale ramp can be opened and closed hydraulically from the cab. This also enables the final bale to be ejected from the driver’s seat.

Changes have been made to the electronic control panel, which is accessed via Cemis 700, Cebis or any other Isobus-compatible terminal. Just two working menus and three settings menus provide a better overview and rapid navigation.

Thanks to an optional Profi Cam 4 camera – with additional display on request – the driver can also keep an eye on working areas such as the knotters, the bale chute, or the area behind the tractor-baler combination when reversing.
