Backed by a global network of 400+ trained and authorised agents, we develop Claas-specific calibrations that improve power, torque and fuel efficiency.
A Harvest Company That Also Builds Tractors
Claas made its name on machines that have to finish. A combine or a forage harvester earns its keep in a few weeks of the year, in whatever weather those weeks bring, and everything about the way a Lexion or a Jaguar is engineered follows from that. The tractors arrived later, by way of Renault Agriculture, which is why an Ares or a Celtis still turns up in the yard alongside the Arion that replaced it. What ties the range together is that every machine in it is bought to get a job done inside a window, and that is the whole argument for optimising and remapping the engine.
Mapped From Arion To Lexion
We have been remapping Claas equipment since 2014. Our platform covers the Arion 400, 500 and 600 tractors, the Axion 800 and 900 ranges, the Xerion 3300 through 5000, the Atos, Elios and Nexos, the Lexion, Tucano and Avero combines, the Jaguar foragers and the Scorpion telehandlers, along with the older machines still earning their keep: the Ares and Celtis tractors and the Mega and Medion combines. Every calibration is written in-house by our UK R&D team for the specific engine.
The Smart Business Case For Claas Remapping
Most of the Claas equipment we see belongs to contractors and larger arable farms putting serious hours on the clock, and at that level fuel is comfortably the biggest running cost. By adjusting injection pressure and timing, we improve fuel efficiency by between 5% and 15% on most machines. The savings show up soonest where the engine is loaded and staying loaded: heavy cultivation, drilling in wet ground, pulling a loaded trailer up a bank.
On harvest machines, the argument isn't fuel; it’s throughput. A combine that holds its output through a heavy patch of laid crop keeps its forward speed and continues to perform. Our harvest calibrations carry the largest gains published anywhere on our Claas coverage: a Lexion 600 goes from 586hp to 735hp, and a Jaguar 900 from 623hp to 780hp. In a wet season, when dry days run short of what the acreage needs, that decides whether the crop comes in.
Contractors have a second reason to look at remapping. When you are quoting by the hectare, the machine that gets through more in a day is the machine that generates more income. Adding output to a Jaguar or a Lexion you already own costs a fraction of stepping up a model, and it doesn’t increase your overhead.
There is a resale argument too. Claas equipment holds its value, so anything you do to it needs to be reversible. Your original map stays on our server and you can go back to it whenever you want, which means the machine you eventually sell can be sitting on its factory calibration.
Finally, nothing we do comes at the cost of reliability. We calibrate within the safe operating limits of the engine and everything behind it, because there is no sense in producing torque that a transmission or a threshing drive was never built to take. Every remap starts with a full diagnostic health check; we back up the original map before we touch anything, and the software carries a lifetime warranty.
Understanding Claas Engine Platforms
Claas does not build the engines in most of its machines, and it has never kept it a secret. The Arion 600 and the earlier Axion tractors run 6.8-litre blocks built by John Deere. The current Axion 800 runs a 6.7-litre FPT, the Axion 900 an 8.7-litre FPT Cursor 9, and the Xerion a 12.8-litre Mercedes-Benz OM 471. What matters for remapping is not whose name is cast into the block, but how few engines Claas uses to cover the range.
One Block, Many Outputs
The 6.7-litre in the Axion 800 makes the point. Claas sells it at 205hp in the 800 and at 295hp in the 870, with the 810, 820, 830, 840 and 850 filling in the gaps. One block, one set of internals, 90hp between the bottom of that spread and the top. Our calibration takes an Axion 800 to 240hp and 1,020Nm. Claas sells the same engine at 250hp in the 840.
The 8.7-litre does the same thing further up. It appears at 320hp in the 920 and at 416hp in the 950, with the 930 and 940 in between. Our calibration takes a 920 to 400hp and 1,688Nm, which puts it past the factory 940 and still lower than Claas is willing to sell from that block.
The pattern runs across ranges as well as within them. The 6.8-litre in an Arion 650 is rated at 175hp. The same displacement in an Axion 850 is rated at 224hp. Our Arion 650 calibration stops at 205hp, well inside what Claas asks the block to do elsewhere in its own line-up.
Although the headroom is real, it’s not unlimited, and the engine is not the only thing on the machine with a limit. The transmission, the axles, the linkage and, on a combine, the whole threshing drive have design limits of their own, and a calibration that ignores them is a calibration that costs somebody a gearbox. Knowing where that stops is what our R&D work is for.
Example Gains From Our Claas Calibrations
Figures taken from our published Claas model pages. Actual gains depend on the specific machine, its condition and the work it does. On the combines, the foragers and the Scorpion handlers, just like the OEM, we publish power figures only. Torque figures for those ranges are still in development.

How We Remap Your Claas
Mapped To Your Spec
If the machine has a PTO, we can measure it. If it does not, and a combine, a forager, and a Scorpion handler do not, your agent will go through what you need from the machine before anything is booked: output through a heavy crop, travel under load, cycle times, fuel over a week. You agree what success looks like up front, and the result is judged on the working machine.
Diagnostic First Approach
Every job starts with a full diagnostic health check. If there’s a fault we want to know before we touch the software. Once it has a clean bill of health, we back the original map up to our own server, so it can be returned to its factory calibration at any point in the future.
Minimal Downtime
In most cases the calibration is done through the OBD port, though some ECUs require bench access. Your agent will confirm which applies when the work is booked. Most installations are completed within a few hours.
Guaranteed Performance
Where possible, we then verify tractors on a PTO dynamometer, the only accurate way to measure what a tractor delivers at the shaft. Many of our agents can PTO test on the farm, so the machine does not need to move. You get a measured figure.
Where a PTO check is not available you can be assured that you’re getting the quoted improvements as all of our calibrations are tested by our R&D team.
Flexible Service For Claas Operators
Most Claas remaps are carried out on the farm. We have a network of 400+ trained and authorised agents across the UK and internationally, and your local agent arrives with everything needed for the diagnostic check, the install and, in many cases, the PTO verification.
If you are based in the South West, or not too far from our HQ just outside Bristol, you are welcome to bring the machine to us. Our workshop has full dyno facilities, and you get direct access to the R&D team who wrote the calibration.
Contractors running a Claas fleet can schedule work across it, and the sensible time to do a forager or a combine is well before the season starts, rather than in the middle of it. Talk to us about phasing it around your year.
Become An Authorised Claas Remapping Agent
Claas owners run long hours, and they judge work by results, which makes them great customers for an engineer who knows what they are doing. Many are contractors with several machines, so the first job is rarely the only job. Adding Claas remapping to an existing service business puts you in front of exactly that sort of operator.
Our agents are backed by the UK R&D team who write every calibration, so you are never installing a generic file. You get the full range of Claas calibrations, comprehensive training, and ongoing technical support from Bristol. We are also the sole UK distributor for Dimsport dynamometers, so our agents work with the best equipment available.
We are selective about who we take on. We are looking for qualified engineers and equipment specialists who can uphold the standards our customers expect.

Common Questions About Claas Remapping
A remap is a modification to the engine software and manufacturers can decline warranty claims relating to it. Most of the machines we work on are past the manufacturer warranty period. If yours is still inside it, speak to your dealer first and then to us, and we will tell you whether it is worth waiting.
Yes, and we publish real figures for both. A Lexion 600 goes from 586hp to 735hp and a Jaguar 900 from 623hp to 780hp. These are the biggest gains on our Claas coverage, which is why harvest machines are worth looking at even if you have already remapped the tractors.
No. Whether the machine is on CMATIC or a powershift, we calibrate inside the torque the driveline was specified to carry. We will not write a map that puts more through a transmission than it was built for, even where the engine could produce it. Protecting the driveline is part of the job.
No. We work within the safe operating limits of the engine and everything behind it. Every job begins with a diagnostic health check, and if the machine has a problem we will tell you before we touch the software.
Between 5% and 15% on most machines. The biggest savings come from engines that spend their working life under load, so heavy draft work and loaded haulage show it soonest. Light work on a big tractor will show less.
Typically within a few hours, including the diagnostic check and the verification afterwards. Most machines are back at work the same day.
On a tractor, in many cases you get a measured before-and-after on a PTO dynamometer, and many of our agents can do this on the farm. A combine, a forager or a Scorpion has no PTO to measure through, so your agent agrees on the measures with you before the work: output through a heavy crop, travel under load, cycle times, fuel over a week. The machine is then judged on those. Our years of experience have given us the skillset to create the improvements customers need with or without a PTO check.
Not if you reverse it. Your original map is backed up on our dedicated server and can be reinstated whenever you want, so the machine can be sold on its factory calibration.
Almost certainly. With 400+ agents in the UK and internationally, most operators have one within a reasonable distance. Use the agent finder to check.
