The changes to the Claas range are extensive and some will be applicable to the Irish market for 2015, when the company aims to make a fresh attack on the mower and wagon sector.
Claas has redeveloped the Arion 400 tractor range with some additional models and power from 90hp to 140hp across six models, compared with three in the past.
Claas is using a Fiat Power Train (FTP) four-cylinder engine in all of the tractors, rather than three-cylinder engines used by some of the competition at this power level.
For each of these models, a number of specification choices, including CIS versions and wider cab options, are available. These include a new panoramic cab, which offers enhanced visibility for loader work.
It has a one-piece windscreen that is joined to the roof pane without a crossbeam, similar to the Fendt 700 series. This gives the operator an impressive 90-degree field of vision over a front loader.
The new Arion 400 models feature a ‘‘wasp waist’’ design to the bonnet, which allows a tight turning lock for maximum manoeuvrability. It also provides space above the front axle for the radiator assembly.
The Arion is built around a solid cast frame with integral oil sump. Where it is to be used with a front loader, the brackets can be bolted directly on to the engine frame and transmission.
A front linkage mounted to the front chassis is available. Claas claims this gives better stability and ease of access for servicing.
Proactive front-axle suspension is also available as an option for models over 90hp. This has a steering lock of 55o and, when activated, provides independent suspension with automatic height control.
The new Arion 400 range is powered by a four-cylinder, 4.5-litre FPT turbocharged and charge-air cooled engine, replacing the John Deere engines for the previous models.
The engine uses a combination of SCR technology and a diesel oxidation catalytic converter (DOC/Oxicat) to meet Tier 4 emissions regulations.
All of the components are housed under the bonnet so that they don’t restrict driver visibility.
The engine is governed by using a Claas engine management system designed to provide different engine performance features.
Transmissions
The standard transmission is a 16 forward/16 reverse speed Quadrishift unit.
The four powershifts and four ranges can be changed manually without using the clutch.
With the CIS models, there is also the option for Quadactiv, in which gear and range changes are automatic.
The Quadrishift transmission and other main operating functions are controlled using a new multifunction control lever. This is designed so that all the gearbox functions can be controlled using a thumb-operated rocker switch.
Depending on specification, the new multifunction control also incorporates controls for the headland and linkage controls. It can be used to operate Electropilot proportional electronic spool valves, or a front loader in either Flexpilot or Electropilot modes.
Hydraulic control options
There are a range of hydraulic options for the new Arion 400 models. For general work, a 60 litres/m open circuit hydraulic system is available.
Where a higher flow rate is required for more demanding work, a 98 litres/m open centre hydraulic system can be specified. This combines two pumps, one with a flow rate of 57 litres/m for the control systems and a second of 41 litres/m for the rear linkage. A 110 litres/m load-sensing hydraulic circuit is also available with optional Power Beyond, which is a first for this size of tractor.
Up to three mechanical or four electronic spool valves can be fitted to the Arion 400. Two additional spool valves can be fitted to the front of the tractor for a front loader, operated by Flexpilot or Electropilot. The spool valves are all colour-coded and an oil spillage container is also fitted to the tractor.
Cab versatility
The Arion 400 models will be available with a conventional cab built on a six-pillar design with the choice of a standard or low profile roof with or without a transparent sunroof.
The low-profile roof gives the tractors an overall height to the top of the cab of about 2.5m on 34in tyres. This is claimed to be one of the lowest on the market for this size of tractor.
Five different Grammer or Sears seats are available. A passenger seat is fitted with a cool-box underneath which is linked to the air-conditioning system.
As on larger models, the length and angle of the steering column and integrated instrument panel is fully adjustable. It can be swung up to make access easier. All the main operating controls are grouped to the right of the driver’s seat, with the secondary controls located on the B pillar.
Where CIS is fitted to the tractor, this enables additional monitoring and setting functions. These include hydraulic and transmission settings, event counters and the on-board computer using a rotary/push switch and an ESC button, with all the information displayed on the A pillar.
The Arion 400 can also be used with the full range of CLAAS EASY electronics systems. It is fitted with cab and rear ISOBUS connections.
Other control terminals can all be mounted on a frame above the control console.
There is a new storage drawer under the right-hand side steps, and the lower link balls are stored beside the rear mudguard.
The tractors are in the Claas range for this autumn, but don’t expect to see them in Ireland or to see prices confirmed until closer to the end of 2014.
Two PTO options are available on the Arion 400 – 540/540 ECO or 540/540 ECO/1000. Speeds are selected using buttons on the B pillar.
There is an automatic PTO function that will turn the PTO on and off according to the height of the rear linkage.
Lift capacity
The maximum lift capacity at the ball ends is 4.5t on the smaller Arion 410/420, rising to 5.75t on the Arion 430-460.
For the front of the tractor, a 2.8t capacity Claas designed front-linkage is available that requires no side reinforcement. A factory-fitted front 1,000rpm PTO is also available, as are connections for three and seven-pin sockets, plus one hydraulic spool and one free-flow return line.
