Highly efficient
Proven transmission components have been intelligently combined with one another in the EQ 200 in such a way that the transmission exhibits a particularly high level of efficiency – more or less constantly at any speed. These components include a multi-step planetary gearbox, a hydrostatic unit and two multi-plate clutches.
Automatically changing gear alters not only the transmission ratio, but also the entire power flow through the transmission. When accelerating, the two clutch shafts gradually adjust their speeds to match each other until they have reached the same speed. The multi-plate clutches then change gear in perfect sync. This means that the gear changes – even under load – without abruptly increasing speed and torque, which leads to consistently steady acceleration from 0 to 50 km/h. Even the driver does not notice that the gear has changed automatically. Furthermore, the tractor can be driven at a top speed of 50 km/h with fuel-saving engine speeds of only 1500 rpm.
New transmission housing design
The design for the transmission housing on the ARION 500/600 CMATIC lowers the oil level in the oil pan, which prevents oil from being lost through splashing. This saves diesel when driving quickly on the road. Nevertheless, up to 40 l of oil is available for external hydraulic power, such as when using large tipping trailers.
Always drive in the right gear
CLAAS has made the ARION 500/600 CMATIC as comfortable to operate as its bigger brother the AXION 900 CMATIC. The driver can switch between driving forwards and reversing simply by using the REVERSHIFT lever on the steering wheel or the CMOTION ground speed control lever on the arm rest. In the ARION 500/600 CMATIC, there is no need to change to first or second gear manually. The transmission always automatically operates in the correct gear, which means that the driver does not have to do anything and it is impossible to drive in the incorrect gear. The ARION 500/600 CMATIC also boasts an active stop feature for additional safety when stopping or when approaching inclines. As in CLAAS other tractors, CEBIS is used to set-up the optimum configuration for the transmission and vehicle. The driver can select the appropriate driving mode at the touch of a button whilst on the move and drives using either the pedals or CMOTION.
