Theoretical investigations have been conducted of the technological process of a sugar beet haulm topping machine with a rotary cutter mechanism, as a result of which there is developed a refined mathematical model of interaction of the cutting blade with a bundle of leaves, the blade being pivotally fixed on the horizontal drive shaft of the arcuate cutting blade. Basic analytical dependencies have been obtained, application of which in designing and constructing of a haulm topping machine will ensure guaranteed quality removal of the bundles of leaves without extracting the sugar beet roots from the soil. The numerical calculations of the obtained analytical expressions performed on the PC, using a prearranged program, made it possible to determine the design parameters of the rotary haulm topping apparatus.
