Many tractors with engine power indicators over 206 kW have power/weight ratio indicators in the range of 1.23 kW/kN – 1.54 kW/kN and belong to tractors of traction concept, are capable of performing all types of mechanized work and transport work without installing additional ballast weights. At the same time, tractors with the specified engine power parameters have a power/weight ratio R = (1.6-2.77) kW/kN and they need to use ballast weights to realize their operational properties. Such tractors include Case IH Magnum 290, Massey Fergusson 8732, Fendt Vario 1050, etc. When using ballast weights, it is essential to consider the requirements for tractor controllability. This requirement is not compulsory for tractors of the 4K4b layout scheme, yet there is a requirement for the distribution of operational weight along the tractor axes when performing agricultural work with various types of machines. Representatives of tractors with the 4K4b layout scheme are: John Deer 9370R, New Holland T9060, John Deer 9520R with respective power/weight ratios – 1.6 kW/kN, 1.67 kW/kN, 2.03 kW/kN. In the study, the authors will consider the possibilities of improving the operational properties of the Massey Fergusson 8732 tractor with power/weight ratios of R = 2.48 kW/kN, the New Holland T9060 tractor with power/weight ratio of R = 1.67 kW/kN.
