Wide product range for a wide market segment

CLAAS introduced a completely new tractor model series in the segment up to 140 hp in November 2014. The ATOS, with 3-cylinder and 4-cylinder variants covering a total of 6 models ranging between 76 and 109 hp, fits in between the ARION 400, AXOS, ELIOS and NEXOS model series.

Harsewinkel / Paris. With the ATOS, CLAAS has expanded its range in the power category below 140 hp and now offers the largest range of tractors in the history of the company with 10 model series and 51 models from 72 to 530 hp. The first tractors of the new model series have already reached their markets.

The ATOS is characterised by its simple and robust technology for day-to-day operations and, thanks to numerous equipment and expansion options, it is an effective machine for any type of use and customer. The tractor was introduced to the public for the first time at the 2014 EIMA international agricultural machinery trade fair held in Italy.

A "True CLAAS"

The new tractors feature the modern, yet functional, CLAAS design and thus fit seamlessly into the large CLAAS tractor family. With its compact dimensions, the ATOS is easily manoeuvrable and ideal for all kinds of farm work.

Large range of power options with four and three-cylinder engines

The ATOS is equipped with a Stage IIIb/Tier 4i-compliant engine, which has 4 cylinders and a 3.8 l displacement in the 300 series and 3 cylinders and a 2.9 l displacement in the 200 series. The engines feature a common rail injection system, turbocharger, charge air cooler and optional viscous fan. Exhaust aftertreatment is carried out by a diesel oxidation catalytic converter (DOC) and cooled exhaust gas recirculation (EGR) system. The catalytic converter is integrated under the bonnet in a compact manner. High torque values of up to 435 Nm provide the tractor with responsive driving characteristics. The fuel tank holds up to 150 l and the standard equipment also includes an engine speed memory function. This simplifies handling for the driver, especially when working with the power take-off.

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 and the TRISHIFT transmission with three powershift speeds (ATOS 350 only). All transmission variants are available with mechanical clutchless reverser or the electronic REVERSHIFT clutchless reverser.

Three power take-off options are also available for the ATOS with the following speeds:

  • 540 rpm
  • 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.

SMART STOP

A special feature of the ATOS is the SMART STOP function for the transmission variant with electronic clutchless reverser. This function is activated at the touch of a button on the dashboard and ensures that the ATOS stops when the brake is actuated without having to depress the clutch pedal. Stopping and starting off is carried out solely using the brake pedal. This relieves the stress on the driver significantly, particularly when working in the yard (front loader operations) or in the field (e.g. when making round bales). The SMART STOP function shuts off automatically at higher speeds.

The ATOS is optionally equipped ex-factory with a fully integrated front linkage with a lift capacity of 1.9 t. 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 and electronically. The ATOS 300 has a maximum lift capacity of 5.5 t at the rear, while the ATOS 200 can lift up to 4.6 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 control units are available, whereby the fourth can be controlled electronically.

The 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 have a wide opening range, thus allowing convenient entry. Thanks to the glass roof hatch, the driver always has a good view of the front loader and can thus work safely and accurately at all times.
