Synchronized driving mechanisms are fitted to cutter bars (12) with multiple mowing blades (32) as a second drive unit operating with a first drive unit to maintain a suitable blade direction and prevent interactions. The second drive unit has a toothed belt (52) or a chain to work with a gearwheel on each mowing spindle. A strain washer is spring-loaded to stretch the driving belt and traction mechanism. |
