The paper presents mathematical models describing the moments of resistance to cutting on the cutting drum shafts in the biomass cutting process. The mathematical procedures described in the paper have been verified on a test stand developed and constructed by the authors, which reflects real conditions of the process of cutting plant material into pieces of specified lengths. Experimental verification proved that the developed mathematical models are adequate for drums of both cylindrical and conical constructions. The value of the average error did not exceed 13%. Following the mathematical elaboration and verification studies, the authors carried out calculations for machines currently available on the market that are equipped with drum cutting units. The calculations were carried out for the most commonly cut material, i.e. for maize, straw and green plant materials. The obtained results confirm the complexity of the problem arising from a wide range of numerical values of cutting resistance, which is contained in the range of 400–1,800 nm. The compiled database can be practically applied in the selection of machines for specific field works, and the mathematical models developed and verified in the study can be applied at the stage of designing new designs of cutting drums used in forage harvesters.

Jedną z ważnych dróg obniżenia kosztów produkcji związanej z materiałem roślinnym jest m.in. zdecydowane zmniejszenie nakładów potrzebnych na jego pozyskanie. Dotyczy to głównie cięcia materiału przeznaczonego zarówno do produkcji żywności, pasz oraz materiału na cele energetyczne. Dlatego w Zakładzie Techniki Rolniczej opracowano stanowiska do badania optymalizacji nakładów energetycznych podczas cięcia materiału roślinnego.

One of major roads to lower production costs connected with vegetable material is i.a. to reduce decidedly the effort needed for collecting them. This refers mainly to cut the material for both the production of food, feed and material for energy purposes. Therefore, the Department of Machines developed the research stands for testing and optimization of energy expenditure during plant material cutting.

In the study there have been presented mathematical dependencies describing the kinematics of the drum movement of a straw cutter’s cutting unit. Formulating of dependencies may be used at the stage of different types of analyses and simulation studies on new drum constructions of cutting units for cutting of a layer of vegetal material into chaff.
