The Claas Arion 400 launched for mixed crop and livestock farms

Claas expands its range of 4-cylinder tractors with the arrival of the Arion 400.
This series slots in between the Axos and the Arion 500, in the 95 to 130 ch tractor segment.

It targets mixed crop and livestock farms looking for a tractor that is equally at home in the farmyard and in the fields.

The Claas Arion 400 range is made up of 3 models: the Arion 410, the Arion 420 and the Arion 430, with a power range extending from 95 to 130 ch ISO.

The new Claas Arion 400 range is offered in two versions: Quadrishift & Quadrishift CIS. The Quadrishift CIS version benefits from the Claas Power Management ?CPM? additional power boost system, available in all applications.

Architecture of the Claas Arion 400

The Claas Arion 400 has a wheelbase of 2,56 m. Its weight is 5400 kg and the weight distribution is 50% at the front and 50% at the rear. Its overall length of 4,42 m and its turning radius of 4,40 m would make it a manoeuvrable tractor, at ease in livestock buildings.

Its lift capacity is 5,2 tonnes or 6,5 tonnes.

The Claas Arion 400 series can also be factory-fitted with a front linkage with a capacity of 2,6 tonnes and a front PTO to drive front-mounted implements.

Reducing operating costs:

The new Claas Arion 400 is equipped with a 4-cylinder DPS engine with a displacement of 4,5 litres. These engines with 2 valves per cylinder meet Tier IIIa standards. They feature Common Rail injection, an intercooler and an internal EGR valve. To increase productivity, the Claas Arion 400 models have a tank capacity of 175 litres.

The CIS version benefits from the boost, which delivers additional power of 10 ch. This extra power is available as soon as range C or D is selected, so it can be used in field applications.

The CPM extra power can also be released to meet increased demand for hydraulic power or PTO power, whatever the gear engaged.

The cab of the Claas Arion 400

The new Arion 400 series borrows its cab from the Arion 600 C 6-cylinder.

The cab is built on a 6-pillar structure with rounded rear windows.

For easy maintenance and cleaning, the floor and the console materials are easy to wash, according to Claas.

For handling work, the roof is openable and glazed.

During periods of high heat, the operator can store a 1,5-litre bottle in the refrigerated compartment.

Inherited from the new Axos series, the Arion 400 has rotomoulded rear fenders for good tyre coverage and better resistance to impacts and corrosion.

The dashboard gathers all the information needed to drive the tractor. The CIS (Claas Information System) version is equipped with a navigator consisting of a dial and an ?escape? key, allowing the setting of various functions such as the adjustment of the 2 electro-hydraulic valves, the shift thresholds of the Quadractiv function and the adjustment of the Revershift reverser ratios.

The Quadrishift transmission

The new 400 series is equipped with the Quadrishift transmission, offering a total of 16 forward and 16 reverse speeds. The Quadrishift transmission has 4 PowerShift ratios over 4 ranges with robotised shifting, so the operator no longer needs to use the clutch pedal or change ranges with a mechanical lever.

The Quadrishift transmission is controlled by a 3-function lever: hand throttle, range skipping and PowerShift ratio shifting. With the right hand, the operator can control both engine speed and the gearbox, making headland manoeuvres easier.

For even more comfort, the Quadractiv function on the CIS version allows fully automated gearbox management via the CIS. Automatic shifting of the PowerShift ratios works in two modes: manual or automatic adjustment of the gear shift thresholds.

This function allows ratio shifting within the engaged range (in field mode) or across the 4 ranges (in road mode).

The Quadrishift transmission features the Revershift reverser, which includes a declutching function for front loader work.

Automation features

In addition to the Quadractiv function, the operator can be assisted by automatic PTO engagement and disengagement. This function simplifies turns at the headland, for example during sowing work.

The Claas Arion 400 can also be equipped with 4 PTO speeds 540 / 1000 & 540 / 1000 ECO rpm, making it possible to optimise fuel consumption depending on the work.

Two hydraulic circuit options

The Claas Arion 400 offers two types of open-centre hydraulic circuit. The first circuit provides a flow of 60 litres/min for the auxiliary valves and the second 98 litres/min by combining two hydraulic pumps. To avoid interference, the steering circuit is supplied by an independent pump.

For intensive front loader work, the 98 litres/min circuit would provide good responsiveness.

As for valves, the Claas Arion 400 offers up to 4 auxiliary valves controlled by manual in-line controls or a cross control.

Note that the new multifunction joystick of the Claas Arion 400 can control the loader or the auxiliary valves, as well as the shifting of the PowerShift ratios.

This new joystick, integrated into the tractor's armrest, is adjustable to suit all body sizes and allows control of the loader and speeds. Available only on the CIS version, this new joystick controls two electro-hydraulic valves with adjustable time and flow.

The Claas Arion 400 and the Claas FL front loader

All Claas Arion 400 models can be factory-fitted with a Claas loader from the FL range.

According to Claas, the loader and frame assembly has been specially designed and integrated for the new Arion 400 range.

Two loader controls are offered: the FlexPilot low-pressure control and the new multifunction joystick.
