A "True CLAAS"
The new ATOS follows the modern, yet functional, CLAAS design and so fits seamlessly into the large CLAAS tractor family. With its compact dimensions, the ATOS is extremely manoeuvrable and ideal for all kinds of farm work.
Large range of power options with four and three-cylinder engines
The ATOS is powered by a Stage IIIb/Tier 4i-compliant engine. The 300 series uses a 4 cylinder engine that has a 3.8 l displacement, whilst the 200 Series has a 3 cylinder engine, with a 2.9 l displacement. The engines feature a common rail injection system, turbocharger and charge air cooler. Exhaust after treatment is carried out by a diesel oxidation catalytic converter (DOC). Cooled exhaust gas recirculation (EGR) system ensures maximum efficiency.
The catalytic converter is integrated under the bonnet leaving clear all-round visibility. High torque values of up to 436 Nm mean that the ATOS is extremely responsive to drive. The fuel tank holds up to 145 l and the standard equipment also includes an engine speed memory function.
Wide range of transmission options
With three different variants, CLAAS offers a transmission to suit every customer. The range includes a standard manual transmission for basic applications, the TWINSHIFT transmission with two powershift speeds or the TRISHIFT transmission with three powershift speeds. All transmission variants are available with either a mechanical reverser or the REVERSHIFT clutchless variant.
Three power take-off options are also available for the ATOS with the following speeds:
- 540 and 540 ECO
- 540/540 ECO, 1000 and 1000 ECO.
An automatic power take-off system and a separate groundspeed power take-off for powering trailers are also available optionally.
New: SMART STOP
A special feature of the ATOS is the new SMART STOP function for the transmission when equipped with REVERSHIFT. When activated, using a button on the dashboard, the system automatically de-clutches when the brake pedal is depressed. Stopping and starting is carried out solely using the brake pedal. This makes SMART STOP ideal for repetitive actions around the yard, especially when using a front loader, and equally in the field, for instance when round baling. The SMART STOP function shuts off automatically at higher speeds.
The ATOS can be equipped ex-factory with a fully integrated 1.9t capacity front linkage. The front linkage console can be operated either with the mechanical PROPILOT control system or the hydraulic FLEXPILOT control system. The rear linkage can also be controlled mechanically or electronically as an option. The ATOS 300 has a maximum lift capacity of 4.8 t at the rear, while the ATOS 200 can lift up to 3.6 t.
The standard hydraulic pump has an output of 55 l/min. The ECO option provides an increased hydraulic output of 60 l/min at a reduced engine speed of 1600 rpm – thus lowering fuel consumption. A total of four spool valves are available.
The ATOS is available in both two- and four-wheel drive variants across all models. The maximum tyre size for the ATOS 300 is 38", and for the ATOS 200 the maximum size is 34".
The new ATOS is equipped with a comfortable four-pillar cab, which provides excellent all-round visibility of the working area. Furthermore, all of the functions are clearly arranged within the cab. The doors open over a wide range, making it easy to enter and exit the cab. Thanks to the glass roof hatch, the driver always has a good view over the front loader and ensuring they can work safely and accurately at all times.
