Introduction

Many John Deere tractors and commercial vehicles have a factory-set top speed limit (VMAX) . This means that even at full engine power, the software limits the speed, often to 40 or 50 km/h , even though more is technically possible. For many customers, this is a real disadvantage in everyday life, especially on longer road journeys.

With our VMAX removal we offer a professional and safe way to remove the limit – without any mechanical modifications.


What does VMAX cancellation mean for John Deere?

VMAX cancellation adjusts the factory speed limit in the system. This is a purely software-based optimization that significantly expands the operating range of your vehicle.

Advantages at a glance:

  • More speed : Up to 60 km/h, depending on the model

  • No performance disadvantage : engine remains in original condition

  • Less idle time on transport routes

  • Professional implementation with secure process


Why Stefanel Performance?

Many vendors promise a lot, but few deliver a clean, risk-free solution. Our VMAX customization isn't a quick-and-dirty hack, but a secure and documented process focused on longevity and system stability.

  • ✔ Optimization without error messages

  • ✔ Retrofitting possible if required

  • ✔ No risk from questionable third-party tools

Our solution is based on years of experience in optimizing commercial vehicles and is therefore hardly available anywhere else on the market.


For whom does the VMAX abolition make sense?

Our customers come from all over Europe:

  • 🌾 Farmers who want to cover transport routes more efficiently

  • 🚛 Contractors who need to save valuable time

  • Export customers who prepare vehicles for other markets

  • 🛠 Municipal companies that need more flexibility


VMAX adjustment process

We offer several options for implementation:

  1. 🏢 On-site programming in our workshop in Bavaria

  2. ✉️ Mobile service for companies with multiple machines (by arrangement)

A powerful charger such as GYSFLASH 100.12 is recommended to ensure a stable power supply.
