John Deere 8Rx V220.127.116.11
A competent team of engine specialists got to work and gave this crawler tractor a few upgrades. The transmission management has been adapted so that it can drive as fast as the normal 8R and the engine has also undergone some revisions. In the first stage, only the software was optimized in order to increase the performance from 458 to 500PS. In the second stage, the turbocharger was replaced in order to achieve an output of 568PS. In the third stage, the engine was given a second turbocharger to increase the output to 680PS. This means that chopping operations with a working width of 6 m are now also possible.
With all the tuning, of course, attention was paid to durability and this is in no way inferior to the production vehicle.
