Doroshenko L. The increase of efficiency of exploitation of technique in the farms.

In theory it has been grounded and experimentally confirmed the possibility of application of mobile-transport vehicles at their use by farmers at field mechanized work with development of mathematical model of traction increase mechanism on the hook of these tools. The program and method of experimental researches at mutual use of machines complex has been given. In theory it has been grounded and experimentally defined the combined coefficient of the use of machine-tractor aggregates on seven field operations while taking into account sizes and forms of farmers plots. The complex of machines for the common use by farmers and the level of concentration of farms for the effective use of the recommended machines complex has been grounded. The calculations of economic effect from the common use of technique, witnessed by the acts of farmers, confirm the expedience of its introduction in agricultural production. Keywords: complex of machines, common use of technique, combined coefficient, farmers, level of concentration, productivity.
