Theoretical Study of Transverse Offsets of Wide Span Tractor Working Implements and Their Influence on Damage to Row Crops

Wide span tractors have a wide transversal bar, on which different implements can be mounted, while the supporting wheels follow the set traffic-lanes.The stability of wide span tractor movement is influenced by unbroken small angular deviations and transversal displacements of the machine due to several factors.These deflections from the set traje
