Adjusting the air supply
For a clean grass flow it is important that sufficient air can flow into the mower. The intake
air is accelerated through the mower discharge together with the cut grass. This is the on-
ly way to exclude the possibility of clogs in the mower or in the suction port.
As a rule, air is supplied through the gap between the ground and the mower. For ex-
tremely dense grass and low cutting height, the gap between the turf and the mower is
minimal. In this case little air can flow into the mower and the grass flow worsens.
In order to optimally mow with dense grass and low cutting height, the mower has three
air regulating disks. These are arranged centrally around the blade units. When opening
the air regulating disks, air from above can flow into the mower and thus ensure a better
grass flow.
