Short answer: We increase the Vmax of the John Deere 6M 155 via software from a factory-set 40 km/h to 50 km/h – in practice, up to 54 km/h are even measurable. The adjustment is OEM-compliant, without additional modules or hardware manipulation, and is carried out completely remotely via AnyDesk, regardless of whether you are 10 or 1,000 km away. More efficiency for road trips and transport.

The John Deere 6M 155 is a true all-rounder in the field and for transport. However, many users quickly hit a limit: The standard VMAX limitation to 40 km/h. With our professional software optimization, we increase this limit to 50 km/h – in practice, up to 54 km/h are even measurable!


The advantages of our VMAX increase:

  • Faster from A to B: Less time lost during road trips or transport
  • More economic efficiency: More efficient use of working time and machine
  • Full OEM compliance: No additional modules or hardware manipulations
  • Remote implementation: Whether 10 or 1,000 km away – the optimization is performed securely via remote maintenance (AnyDesk)

Technical process

  1. We send you all the necessary information for preparation
  2. We connect via AnyDesk and take care of the rest

A good charger like the GYSFLASH 100.12 is essential for this process to keep the on-board voltage stable.


Important: Usage Note
