These tractors are pumping
CLAAS has announced it will introduce a new automatic tyre inflation system across its AXION and ARION series of tractors.
All CARGOS 700 series models of wagons can now be equipped with a mechanically controlled hydraulic positive steering system as an alternative to the existing passive or electronically controlled hydraulic positive steering systems.
Utilising the displacement principle, the mechanical hydraulic positive steering system utilises one (tandem models) or two (tridem models) master cylinders on the drawbar, combined with a hydraulic unit and a high-volume pressure accumulator as overload protection.
CLAAS Harvest Centre product manager Luke Wheeler says the master cylinders are attached on the tractor side on Scharmüller K50 ball hitches, and each is protected with a robust bolted guard plate.
“There are also pivoting supports for the master cylinders,” he says. “The steered axles are the rear in a tandem layout, and the first and last axles in a tridem chassis.
“When the machine is in operation, the positive steering function is controlled by the tractor, without any permanent electrical connections.”
Mechanical operation of the hydraulic system is said to allow optimum soil protection during reversing manoeuvres and provides excellent trailing alignment on both level and sloping terrain.
Additionally, all new CARGOS models can now be fitted with the ISOBUS-compatible CEMIS 700 universal terminals. This features a 7-inch, high-contrast colour display with touchscreen functionality, an automated day/night switch, 10 backlit hard keys and a rotary/push switch for easy operation.
Other features include input from one or two cameras, ISO 11783 compatibility alongside Aux-O, Aux-N, UT1 and UT2 functions.
On the capacity front, thanks to a platform gate extension, the capacity of the CARGOS 8400 dual-purpose wagon has increased by 7% to a DIN loading of 38 cubic metres.
