6.3.6 Mowing deck – checking and maintenance of the mowing blades
Before each use of the riding mower check the condition of the blades (damage, wear, condition of the
cutting edge). If the blades are blunt, bent or broken it will negatively affect mowing quality. Damaged
blades are very dangerous.
A part of the material could break off and be deflected from the work area of the machine.
Whenever handling the mowing blades, always use heavy-duty work gloves.
u REPLACING BLADES
If due to frequent use the blades are worn or damaged, they cannot be balanced or sharpened properly,
it is necessary to replace them immediately.
