125 horsepower
Maximum velocity: 40 km/h
Configurations:
- Front plate, front weight (350 kg), or front hydraulics - Tires (Trelleborg, Vredestein)
-Exhaust - Low/high air filter systems

• The mouse wheel may be used to open or shut the roof window

There are still some warnings in the mod because of the conversion, but I'm trying to get rid of them.
