The paper presents original results obtained by the authors in the energy field of the miscanthus plant aggregates, using a four-row planter, equipped with various covering organs. An original mathematical model of fuel consumption in the planting of miscanthus rhizomes is presented, obtained by an original theoretical-empirical method, based on the experimental data obtained with the help of original conception experiences, in correlation with traction resistance of the machine. The experiments performed implied different use of the working organs of the four sections of a miscanthus rhizome planting machine, each section consisting of a hoe ploughshare, but different covering organs (cover plates and a simple metal wheel for compaction, respectively two coating and compaction wheels arranged in V-configuration). The 75 experiments performed had three different working depths (0.06, 0.09 and 0.12 m), each having its own moving speed. Resulting values for specific fuel consumption were introduced into a program made in Mathcad, and by the least squares method using the mathematical model presented in the paper, the specific fuel consumption coefficients were determined for each of the five types of work organs (ploughshare, cover plates, simple compaction wheel, compaction wheel with wings, respectively the rolling train of the machine).
