A crucial part in feeding the ever growing world population is a significant productivity increase of existing agricultural machinery. Besides the engine power, also the vehicle weight, the grain tank capacity, and the cutting width of the front-end equipment is steadily increasing. With the giant headers, it has become essential to use header control systems which help to maintain a constant height of the front-end equipment above ground. This paper discusses potential solution approaches for reducing the undesired effects of harvesting machine dynamics and names structural limitations. Two concepts for improving the ride comfort and the header height control performance are presented, which do not require major hardware design changes. Within the first concept demonstrated, it is investigated if a command shaper can be used to proactively suppress self- induced vehicle oscillations. Within the second concept, it is examined whether the inclusion of the vehicle speed as additional control variable can improve the vehicle stability. Results from simulations and field tests are presented in order to give insights in the improvement potential.
