Use only original blades with the
order no. specified next to them.
Employment of wrong or unsuitable
blades may lead to accidents!
3.8 Changing Blades on the Cutting Discs
with Blade Screw Connectors
Safe and reliable operation of the mower is only
guaranteed with correctly fitted cutter blades.
Missing and damaged cutting blades cause dangerous
irregularities in the rotation. Cutting blades and fixing
bolts must therefore be checked daily.
Always inspect the mower before starting work to check
for damaged, missing or worn cutter blades. Replace
blades if necessary.
The upper section of the adjacent diagram shows
individual parts required to mount the blades and the
positions of the blades on one disc. The procedure for
mounting on the mower drums is identical. Screws (3)
and nut and washer assembly (4) are required to mount
the blades (5). Insert the screws from below through the
wear plate (2). The blades are fitted between the wear
plate and the blade disc (1). Tighten the screws from
above with nut and washer assemblies (4).
After mounting, the blades on the screws must be able
to move freely.
A number of different types of blade can be mounted on
this mower unit. The universal blade has a crossed
(twisted) shape. The blades are classed as:
Blades for
Cw rotating disc Order-No. 139-889
Ccw rotating disc Order-No. 139-888
All blades have a corresponding
designation. The arrow on the blade
should be pointing in the direction of
operation!
It is also possible to mount so-called roof shaped
blades. These can be employed identically with discs
which rotate to the left or right.
Roof shaped knife Order-No. 139-800
