The overlaid cut in a disc mower – results from field tests and simulation

Abstract

Modern rotary mowers are well known in green forage harvesting. These machines are powerful and reliable, but energy consumption is high and cutting quality is restricted. To optimize the process, an overlaid cutting principle was developed and realized as functional prototype. This cutting method is characterized by two vertical arranged mowing discs with several blades. Thus with reduced cutting speeds the energy efficiency and the cutting quality could be improved.
