<p>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 unter tension, so pressing the driving units (36) and the intermediate pieces (35) together to make the main frame (6) substantially rigid. The driving units (36) have cutting units (8) which are driven by a drive shaft (41) through bevel gearing (46, 47). The driving units each have a shoe with a protecting means for the cutting units. The direction of rotation of each cutting unit (8) can be altered by removing the gear (46) and replacing it the other way round.</p> |
