CLAAS has expanded use of its dialogue-based operator assistance system, Cemos, to the Axion 900 Terra Trac half-track large tractor series.

Having established a technological lead with the self-learning operator assistance and machine optimisation system for combine and forage harvesters, in 2020 Claas extended this technology to the tractor sector with the launch of Cemos for tractors.

But the half-track series required the tyre pressure and ballasting areas to be specially modified, since a far greater proportion of the tractive force is transferred via the rear axle and crawler track assembly compared to standard tractors. Plus wheel weights cannot be used on the rear axle.

So the system developed for the Axion Terra Trac only covers the internal tyre pressure on the front axle, while the driver simply enters the belt width of the crawler tracks once under basic settings.

Since the crawler tracks have a larger footprint than conventional tyres and the crawler track assembly is heavier, extra ballast is not normally needed on the rear axle.

In addition, later this year the implement assistant will be extended at no extra cost to include disc mowers.

The mower assistant is designed for all brands of mounted rear and front mowers as well as front-rear and butterfly combinations. The driver enters the working width just once, followed by the basic settings such as crop, the type of placement and the pto speed.

Then, Cemos helps the driver correctly align the mower bar, set the right cut height and ground pressure, adjust the lift height and select a suitable overlap.

The system takes care of basic settings such as adjusting the lower and upper links and securing the rear lower links with the side stabilisers, as well as ensuring that the drive shaft is the correct length.

Cemos for tractors also helps the driver select the suitable conditioner speed and makes recommendations for adjusting swath drums or swath discs before starting a job.

All conventional laying strategies are stored in the system for mowers with swath merging systems. In addition, Cemos suggests suitable settings for the belt or screw speed. If a mower combination is equipped with hydraulic ground pressure slope adjustment and swath merging, that can also be catered for.

To further reduce the driver's workload, Cemos can also help with programming the headland management system and assigning the function buttons, especially when working with Isobus.

It also assists with transport position settings for on-road travel, for example by ensuring that the mower bar on front mowers is locked or that the maximum permitted transport height is not exceeded.
