Study on stability at work for tillage aggregates

Abstract

This paper shows the importance of stability at work for tillage aggregates, from the point of view of work quality and fuel consumption. The classic ploughing aggregates are analysed, from the point of view of stability at work, as agricultural milling cutler and aggregate plough – agricultural milling cutler, accentuating the way in which the soil reaction on socket-rod can be influenced. The value of socket-rod pressure on the vertical furrow wall must be optimized, because a higher value for this force leads to the friction force increase and to the destruction of the vertical wall, while a smaller value leads to the aggregates instability at work. From this point of view, the aggregate made of plough and milling cutler carries under all the stability conditions.
