The tractive effort of heavier terrain-vehicles is by tradition developed through an aggressive contact with the ground. This causes soil compaction and damage to roots and vegetation. The terrain-vehicle design may be improved in such a way that less damage is caused. The most important machine features in this connection are: power train, dimension, weight, geometry and dynamic behaviour, the choice and construction of contact faces between machine and ground/trees. By changing the characteristics of these features one by one and in combination, the effect of machine design on damages may be analysed. The research project 'Smoother terrain-machine' involves such studies. In the project a test vehicle permitting changes in individual characteristics is developed. In the first phase torque is measured on each wheel under different controlled conditions and the interaction between wheels through power train and steering geometry is analysed. So far the result shows that wheels on a terrain-vehicle can under many working conditions counteract each other and cause high torque in the power train and high driving and breaking forces in the ground contact, while the effective torque for transportation is very low.
