Abstract
A mowing machine comprises a main frame (6) made up of driving units (36) and intermediate pieces (35) which are mounted alternately on a tie member (42). The tie member (42) is placed under tension, so pressing the driving units (36) and the intermediate pieces (35) together to make the main frame (6) substantially rigid. The tie member (42) is positioned substantially centrally of the driving units (36) and the intermediate pieces (35) so as to provide even loading of their mating faces. The driving units (36) have cutting units (8) with flexible hoods. The cutting units are driven by a drive shaft (41) through bevel gearing (46, 47). The direction of rotation of each cutting unit (8) can be altered by removing the gear (46) and replacing it to the other way round.
