Following the successful launch of the high-horsepower Xerion 5000 (530hp) and 4500 (490hp) models two years ago, the new Xerion 4000 (435hp) will join the range for 2014. All three will benefit from new engines and a number of other updates and changes.
The Xerion has proven itself in both arable and more specialist applications, being ideal for heavy cultivations or more specialist work such as slurry and digestate spreading, silage clamp buckraking or for specialist work such as timber processing.
The new addition to the range, the Xerion 4000, has a maximum power output of 435hp and will be available in three versions: Trac with a fixed centrally positioned cab, Trac VC with a rotating cab or Saddle Trac which has a forward-mounted cab.
The new Xerion 4000 follows the same design as the two larger versions and follows the same design concept that has been central to all Xerion models. Central to the Xerion is the Trac concept of building the tractor around a full-frame load bearing chassis from which the main components are suspended, in which the cross bracing is now bolted on rather than welded for added strength. The four large equal sized wheels, enable the Xerion to put down a large tyre contact area for minimal wheel-slip and maximum traction, ensuring optimum efficiency.

This unique design results in a tractor that is highly manoeuvrable, is capable of safely carrying large loads but able to efficiently convert engine power to tractive power, so ensuring high output and low running costs. The Xerion is also the only tractor in this high horsepower sector to have a 50km/hr CVT transmission, making it far more versatile than similar sized articulated or tracked tractors.
All three Xerion models are powered by Stage IV compliant Mercedes engines that use SCR catalytic converter technology. The high-performance characteristics of these engines mean that they develop maximum torque at between 1,450-1,500rpm and remain torque stable over a wide engine speed range, making the engine extremely fuel efficient when used for high traction applications such as cultivating.
Fuel efficiency is further enhanced by the use of a hydraulic reversible fan with automatic speed adjustment based on a number of factors including the coolant temperature, and the hydraulic or transmission oil temperature. The engine also features charge-air cooling using air drawn in from the top of the bonnet, and is started using a 24-volt on-board supply. And as part of the design restyle, the exhaust has also been moved to the right-hand side under the cab.
Drive to the four equal-sized wheels is through either an Eccom 4.5 or 5.0 CVT transmission. As before, the Eccom 4.5 transmission provides full power and a maximum speed of 50km/hr at a reduced engine speed in either direction. For those who will mainly just use their Xerion for heavy cultivations, the optional Eccom 5.0 transmission is 500kg lighter, has a reverse speed of just 30km/hr and has the option of not having a PTO coupling.

Each axle is designed to handle maximum loads of up to 15t and as before has a total of six different steering modes with a minimum turning circle of just 15.7m. The design of the Xerion also ensures that overall road width is kept to a minimum, measuring just 3m wide when fitted with 710mm tyres.
The full frame chassis provides the Xerion with a wide range of ballasting options to ensure even loading between the axles and maximum traction. Up to 6.8t or 5.0t can be carried on the front and rear linkage respectively, while a further 3.4t can be carried on a base plate behind the cab.
In the cab, all the main operating functions are controlled using the new CMotion multifunction control lever. This is designed so that all the main functions are operated using just three fingers, and also incorporates a hand rest.
The thumb is used to control functions such as the hydraulics, changes in direction, CSM headland management and GPS steering. The index finger is used for cruise control and two programmable buttons, while the middle finger panel incorporates a freely programmable rocker switch for functions such as engine speed or hydraulics.
In addition, the whole lever can be moved forwards/backwards and sideways to change speed and wheel angle, for instance when crab steering.
Using a combination of Cebis and the CMotion control, the operator is able to set-up and control a wide range of operating functions, including three different driving modes. In Automotive the transmission ratio and engine speed are automatically regulated according to the speed selected using the foot throttle. With Cruise Control, the engine speed is automatically regulated for optimum efficiency whilst maintaining the forward speed set using with Cebis or the CMotion control. E-Gas enables a constant PTO speed to be maintained at optimum engine efficiency.

Cebis can also be used to alter various operating parameters, such as engine droop value, allowing specific engine characteristics to be set-up and saved for different operations, or for hydraulic flow rates to be adjusted for individual spool valves.
As standard, the Xerion is equipped with a 195 lit/min hydraulic circuit operating at up to 200 bar, with flow rates of up to 105 lit/min available for each spool valve, and up to seven rear and three front spools can be fitted. If required, a Power Hydraulic system with a maximum flow rate of 250 lit/min at 1,650rpm can be fitted for use with equipment such as swan neck slurry tankers.
As with all the main operating systems on the Xerion, the electronic linkage is easily set-up using Cebis and operated via the CMotion control. The rear linkage has a maximum lift capacity of 10t, while the front linkage has an 8.1t capacity.
The spacious cab includes the availability of a number of seat options, generous storage including a cooler compartment under the passenger seat, excellent all-round visibility and numerous connection options, including Isobus and is fully PGS ready. The Xerion can also be specified with Claas Telematics enabling full performance data to be monitored and recorded and is also ready to work with the new TONI (Telematics On Implement) and ICT (Implement Controls Tractor) operating systems.
