In its newest announcement Claas launched a number of new tractors from both finish of its vary together with the newest Xerion 12 which, on nearer examination, seems to be a serious step ahead for the corporate.
Whereas the smaller Axos machines have been a growth of present fashions, the 2 new Xerions are dramatically totally different from their siblings within the Xerion vary.
Identical recipe, larger cake
Claas has saved the Xerion idea of a bolted body and two steering axles powered by a Mercedes Benz engine, however have in any other case began with a clear sheet of paper to deliver these newest giants to life.
There are two fashions on this vary which has been named the Xerion 12 sequence.
The smaller machine, the 12.590, has 585hp on faucet whereas the bigger 12.650 gives 653hp. These are exceptional sufficient figures, but most torque on the 12.650 is available in at 3,100Nm and the hydraulic pump can ship as much as 537L/minute which is claimed to be the most important in the marketplace.
Mercedes Benz has been chosen to provide the ability with similar 15.6 l OM473 LA six-cylinder in-line engine that’s already utilized in Jaguar harvesters and Lexion combines.
Though it’s unashamedly a classy engine servicing, it’s stated to be comparatively simple with an oil change interval of 1,000 working hours and a maintenance-free Stage V exhaust gasoline after-treatment system.
CVT as customary
The brand new Xerion 12 Sequence is supplied with the newest era Cmatic constantly variable transmission (CVT), which once more is claimed to be maintenance-friendly and sturdy.
CVT-type transmissions have gotten recognised amongst all the foremost producers as being the reply to greater energy outputs the place any inefficiencies can incur a a lot higher monetary penalty.
Due to a tractor’s CANBUS system they can be higher matched to an engine’s optimum energy, torque and consumption traits as working efficiency is continually monitored and the engine velocity and gearing adjusted to take care of most effectivity.
Gasoline effectivity is simply a part of the equation in accordance with Claas, there’s additionally the working traits of a CVT to be thought of with one of many chief advantages being the light beginning and deceleration torque.
Xerion 12 sequence, light giants
CVTs break up the ability transmission between the hydraulic and straight mechanical connection, with the previous getting used to start out off earlier than the hassle is step by step handed to the mechanical aspect because the velocity will increase.
This attribute implies that implements are protected by the avoidance of peak masses on the body buildings and hitching units attributable to abrupt shifting or participating and disengaging with the implement in working place.
Hitching up 653hp to what’s, in impact, a floor anchor, goes to trigger an terrible lot of pressure on the parts concerned so this capacity of CVTs to keep away from subjecting them to shock stresses is a serious profit.
Nonetheless, the Xerion nonetheless delivers the total engine torque from the minimal velocity of 0.05km/h, a capability that convectional drivelines merely can’t match.
Tracks vs. wheels
Eire, and even a lot of the UK, just isn’t fairly prepared for 650hp tractors, and so these stay markets which could see occasional gross sales. The actual targets areas are, in accordance with Claas, North America, central Western Europe, South America and Australia.
For the UK and Irish markets the tractors can be found solely as tracked items, for the primary gross sales areas there would be the choice of wheeled variations.
The steering axles, every with two auxiliary steering cylinders and hefty drive wheels, are stated to switch energy gently to the drive belts by participating eight lugs concurrently.
The 2-part body building of the tack meeting allows the pair of mid-rollers, that are mounted on their very own bogies, to adapt to floor contours independently of the primary body.
Giant rubber blocks between the undercarriage and the primary body of the crawler monitor meeting successfully buffer bumps and vibrations.
50-50 weight break up
There are 4 routinely chosen drive modes which, together with the multi-pass impact, be certain that energy is transferred to the bottom whereas additionally making certain most soil safety whatever the steering angle.
Weight is equally distributed between the 2 axles which stays fixed all through the working day because of the 1,400L gas tank being centrally mounted.
The steering behaviour is claimed to be much like that of normal tractors with steering manoeuvres and turning operations being driver-friendly with minimal monitor formation on the sector floor.
The cab has been prolonged by 27cm on the entrance, making it presently the most important unit within the premium tractor phase, in accordance with Claas.
The cab has 4 mounting factors to offer full suspension and 4 additional consolation footrests could be factory-fitted behind the steering column and on the right-hand A-pillar.
The motive force’s seat is on the market in three variations with customary upholstery or optionally available high-quality cotton or leather-based upholstery. It might even be rotated by 40° to offer the motive force an ideal view of connected implements.
The exhaust, together with its aftertreatment system, is totally built-in into the right-hand aspect of the chassis below the cab. This, together with the slender steering column, ensures good all-round visibility.
CEMOS carried over to Xerion 12
CEMOS is the onboard digital know-how which Claas describes as a “self-learning, dialogue-based operator help and course of optimisation system”, can be fitted to the Xerion 12 sequence after its profitable use in different Claas CVT-driven fashions.
Claas tells us that “double-digit proportion enhancements in gas consumption and space output could be achieved by optimising energy transmission, drive administration and ballasting”.
As well as, the system incorporates the Terranimo app which, as soon as the working circumstances have been entered, calculates the compaction threat in three soil layers to assist the motive force optimise the machine settings in favour of higher soil safety.
The Claas Xerion 12 sequence will probably be out there for buy from early 2024 onwards.
