The mower unit
The Groundkeeper has a flail-type mower unit. This involves free-
moving cutting tools which are suspended on a large-diameter tube.
When the rotor starts to turn, the cutting and scarifying blades are
erected by centrifugal force, which allows them to reach into the grass
which is to be cut and mow it off. The blades are made of special
steel and suspended in four rows around the rotor from so-called clip
bolts
6.1
Fitting the mowing and scarifying tools
There are 5 different tool arrangements as shown in table 11.
If the mowing blades (tab. 11, A) or scarifying blades (tab. 11, B) have
been worn out on one side only, they can be turned round and used
again. This is possible because both the front side and the rear side
of the blades have been provided with a cutting edge.
The blades can be turned or replaced without the use of tools (Fig.
6.1-1).
Care must be taken to ensure that the rotor is evenly fitted with
blades. If cutting tools are missing or have been incorrectly fit-
ted, an imbalance is created which, over time, will lead to the
whole machine being damaged.
