CUTTING UNIT
Blades and blade holders are made from high-alloyed hardened materials. A special
heat treatment results in an especially hard and ductile material which can handle
extreme stress. If a blade or blade holder is damaged, do not attempt to weld the
parts together again as the generation of heat will destroy the material properties and
expose you and others to increased risk.
IMPORTANT : Damaged blades, blade holders, drums and rotors must be
replaced by original KONGSKILDE spare parts to obtain safe
operation.
WARNING: Always lower the cutting unit to the ground before replacing
blades. Replacement of blade holders, rotor skirts, drums and
guide shoes can take place with the machine lifted in the link
arms of the tractor and secured mechanically by e.g. support
chains.
BLADES
When replacing blades, the cutting unit must be lowered or secured by means of stop
blocks or support chains. The blades must be replaced in sets to avoid unbalance.
To obtain satisfactory cutting it is important that blades are intact and sharp. If the
blades are not sharp the power requirement will increase unnecessarily and the cut
will be unclean resulting in slow regrowth of the grass.
The blades have two cutting edges and can be worn on two sides.
-
Remove straight blades to the neighbouring rotor.
-
Turn twisted blades.
