The work is focused on description of tractor individual axels and wheels loading during ploughing. A combination of tractor inclination with force and momentum effects need not always result in marked differences in the load of driving wheels. This paper documents the relationship existing between forces working in the upper drawbar Fh of the three-point linkage and the momentum MTx. It was also demonstrated that with the increasing value of MTx the difference between loads of both rear wheels reduces. The described algorithm enables to evaluate output parameters of ploughing aggregates for different variants of forces changing in the tractor three-point linkage due to various ways of suspension and adjustment of individual plough types. When using data recorded in the course of ploughing operations it is possible to demonstrate the effect of plough adjustment/attachment on the efficiency of the whole ploughing aggregate.
