Regrinding the Mowing Knives
Wear safety goggles and
safety gloves.
After 4–20 operating hours, depend-
ing on the strain the mowing knives are
exposed to, they become blunted and
regrinding is necessary.
For this purpose, we recommend to use
a hand grinder of 15,000 to 20,000 rpm
with a pot-shaped grinding pin of 25 mm
in diameter and approx. 35 mm in length
or a special grinding tool.
