A mathematical model of the cutting process of the sugar beet leafy tops without a tracer

A method is proposed for the assessment of the effect of the soil surface irregularities upon the loss of mass and the residues of the leafy tops during the sugar beet harvesting process. A new mathematical model is constructed and dependences of the loss of mass and the top residues are obtained depending on the distribution parameters of the soil surface irregularities. The established dependences of the loss of the root crop mass and the residues of the leafy tops on the root crops depending on the statistical distribution parameters of the soil surface irregularities and the cutting height of the tops without a tracer allowed justification of an agrotechnically acceptable level of mathematical expectation of the soil surface irregularities and the cutting height of the root crops without a tracer.
