Unveiled at EIMA in November, the new six-model range of Claas Atos 3- and 4-cylinder tractors (76 to 109hp) will be on show for the first time in the UK at LAMMA. A wide range of transmission and specification offers are available for each model.

For those who just need a simple, straight-forward tractor for livestock work and the minimum of electronic control systems, the Atos is available with a 10 forward/10 reverse speed mechanical transmission and mechanical reverser. For greater functionality and especially when used with a loader, the Atos can be specified with a Twinshift two-speed or Trishift three-speed powershift transmission and Revershift clutchless reverser.  

The specification options across all models includes the availability of either 2 or 4wd, with the choice of either a 540/540 ECO or 540/540ECO/1000/1000ECO PTO, with the ECO option providing a 60lit/min hydraulic output at a reduced engine speed of 1,600rpm.

A new feature is the Smart Stop function on models with Revershift. When engaged, this enables the transmission to be automatically de-clutched when the brake pedal is engaged, making this option ideal for repetitive yard or loader work. 

Also on display for the first time in the UK will be the new Arion 400. Aimed at users needing a slightly higher specification and increased power and capacity, power to the six models comes courtesy of an FPT SCR 4.5 litre (90-140hp) engine that has no boost, so full power is always available. 

Reflecting the fact that a lot of tractors this size are used with front loaders, all Arion 400 models can be specified with the new Panoramic cab option. This features a one piece windscreen and roof panel, giving an uninterrupted view over a 90 degree arc. Smaller Arion models are also available with a low-profile cab, with an overall height of just 2.5m.
