Checking the mowing blade wear limits
Risk of injury:
A worn mowing blade may break off
and cause serious injuries. The
instructions for blade maintenance
must therefore always be observed.
Mowing blades are subjected to
differing degrees of wear
depending on the location and
duration of use. If you use the
machine on sandy ground or use it
frequently under dry conditions, the
mowing blade will be subjected to
greater loads and will wear more
quickly than normal.
Caution:
Always replace the blade
fastening screw and the retaining
washer when replacing the mowing
blade.
VIKING recommends removing the
mowing deck if the wear limits need
to be checked.
If a suitable lifting platform is
available, the mowing blade wear
limits can also be checked with the
mowing deck installed.
● Carefully clean the mowing blade and
mowing deck.
● Remove the mowing deck. (

Placing the mowing deck in safe
position for checks
Lean mowing deck (1) against a wall and
secure against slipping with the foot.

Checking the wear limits
A = blade thickness
B = blade width
Blade thickness A:
The mowing blade (1) must be at least
2.5 mm thick at all points.
Check the thickness of the blade at several
points using a slide calliper (1).
If the blade thickness is less than 2.5 mm
at any point, the mowing blade must be
replaced.
Blade width B:
Measure the distance (B) using a slide
calliper.
For safety reasons, distance (B) must be
at least 65 mm.
