The mower unit
The Groundkeeper / HorseHopper is equipped with a flail-type mower
unit. In this type, cutting tools are suspended freely on a large-
diameter tube. When the rotor starts to turn, the centrifugal force
moves the mowing and scarifying blades into an upright position
which causes them to engage with and mow the material below. The
blades are made of special steel and are suspended from clip bolts in
four rows around the circumference of the rotors.
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) are
worn on one side, they can be reused by turning them round as these
blades have a cutting edge on the front and rear sides.
The blades can be turned or replaced without the use of tools (fig.
6.1-1).
Care must be taken to ensure that the blades are uniformly dis-
tributed on the rotor. If cutting tools are missing or incorrectly
mounted, this will cause an imbalance that, over time, will lead to
the whole machine being damaged.
