The investigation of modern factors affecting the efficiency of machine and tractor aggregates

In the modern world, a person is increasingly striving for an industrial society, accumulating power and trying to invest it in one multifunctional machine that will perform several operations in one pass over the surface of the field in the production of agricultural products. This is how various agricultural complex machine-tractor aggregates, which make it possible to carry out soil cultivation with simultaneous fertilization in one pass, or soil cultivation with simultaneous sowing and fertilization. The use of such machine-tractor aggregates makes it possible to reduce labor costs and funds for further processing of cultivated crops, to reduce the negative impact on the soil structure and the environment, as well as to increase the productivity of machine and tractor units and as a result the yield of cultivated crops. However, the bet placed on soil preparation and fertilization cannot always give the desired effect without due attention to seed material and maintenance of agricultural machinery. Therefore, pre-sowing soil preparation, preparation of seed material and machine-tractor aggregates, as well as timely and high-quality performance of maintenance operations for equipment is an urgent problem of modern agricultural
