What is the difference between the vehicle weight and the maximum total mass in the tractor parameters?
8.8 tons refer to the weight of your tractor. 25 tons refer to the total weight of your tractor
That is to say, your traction weight is 25 tons of your total traction, minus the weight of your tractor by 8.8 tons, equal to 16.2 tons, and you can draw 16.2 tons of weight
