During the last decades fatigue life of agricultural machinery is gaining more interest as the transport and working conditions have changed. Transport and working speed have increased since advanced and more powerful tractors are being offered. In order to compensate for longer operation periods on large farms, manufacturers have developed bigger implements with higher capacity which in some cases e.g. for swathers reach up to 15 meters working width. Factors like higher speed and machine weight affect the durability of agricultural machines with high economic loss in the case of a breakdown. In order to assess agricultural machine durability a new analysis approach is needed to combine field and road surface mapping and dynamic strain and load measurements. In the present paper strain data from critical points of a four rotor swather were recorded as well as the accelerations on the main axle. In addition the surface data that produced the aforementioned load were also obtained to describe the dynamic input loads
