In order to provide more effective secondary separation and greater throughput, the centre risers of the straw walkers have been redesigned to loosen the crop mat even more effectively and to enable a faster transfer to the next straw walker racks. Another important factor – in addition to the threshing concave overload protection – in ensuring operating reliability is the sensor-based monitoring of the crop flow on the straw walkers. As soon as any blockages begin to develop there as a result of difficult harvesting conditions, the operator receives early warning both in the form of an audible alarm and as a visual alert on the CEMIS terminal display. In addition, the optional CEMOS AUTO CROP FLOW automatically deactivates the front attachment and the feeder unit in the event of any imminent risk of blockages on the threshing drum or serious belt slippage so that no more crop is fed in. This avoids unnecessary downtime.

The XERION Series comes with a customisable package for ISOBUS and precision farming applications. Buyers can choose from automatic steering by GPS PILOT with different correction signals, both on- and off-line Task Management, and precision farming applications with Section Control and Variable Rates Application (VRA). All functions for modern, precise and site-specific work are available in conjunction with the -inch CEMIS terminal which uses the familiar CEBIS control concept. With CLAAS connect, new licences or activations can be transferred straight to the terminal online, as can tasks with predefined tracks and application maps from connected farm management information systems (CLAAS API).

Two counter-rotating polyurethane rollers crush the crop gently yet effectively without loss. The conditioner spans the entire width of the mower bed to ensure continuous linear flow without forage bblockages. Optimised crop transfer to the mm wide, extremely robust Kevlar-reinforced cross conveyor belts ensures uniform filling of the AUTO SWATHER belt units. This produces an even, loose and perfectly shaped swath which the harvester following behind can easily pick up and process.

The tramline management feature in CEMIS also reduces the workload significantly. The driver can specify in advance where the first tramline is to be created and the interval between tramlines (in x times working width). The tramlines are then highlighted in colour on the CEMIS screen as work is underway. In addition, an acoustic signal can also be activated to remind the driver where exactly in the field to create a tramline. This means tramlines can no longer be missed – for example when drilling cereal, maize or beets, planting potatoes or creating interval tramlines on slopes – allowing the driver to focus fully on monitoring and operating the machine. It is also possible to configure the signal to sound only when driving onto a tramline, or when leaving it as well.

As well as focusing on using high-quality, proven components, delivering uncompromising threshing quality and ensuring operating reliability, even under difficult harvesting conditions, the development team have ensured that the EVION is easy to use. It is therefore equipped with a single-drum tangential threshing unit with a large,  mm threshing drum and a synchronised impeller combined with five .-metre-long straw walkers and a feeder housing width of , mm. This results in an impressive threshing concave area of . m
