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.
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.
Machine GC 92 (mowing deck with a mowing coverage of 92 cm):
Always completely replace both blades and use new M16 lock nuts for attachment. This will ensure that the
mowing deck is balanced and that the blades are securely attached. Proceed as follows:
Turn off the engine and take the key out of the ignition.
Secure the machine against movement.
Elevate the mowing deck to the transport position.
Open the metal cover on the right of the mowing deck chamber.
Screw out the M16 lock nut.
Take off the fasting bolt, O-ring and blade.
Install a new or sharpened blade proceeding in the reverse
sequence.
Use new, unused M16 lock nuts.
Before replacing the second blade turn the blade holder with your
hand by 180°.
Replace the second blade following the same procedure as for
the replacement of the first blade.
When reinstalling the blades, ensure that they are correctly fastened
and secured in place!
The blades are sharpened from both sides so in the event that one side is blunt, it is possible to turn
the blade around.
Machines GC 110 (riding mowers with a mowing coverage of 110 cm) and GC 132 (riding mowers with a mowing
coverage of 132 cm):
Turn off the engine and take the key out of the ignition.
Secure the machine against movement.
Elevate the mowing deck to the transport position.
Tilt the machine to the right side and prop it up using suitable supports.
It is recommended to invite another person to help with tilting the
machine in order to prevent damaging a part of the machine or an
injury.
Screw out three fastening bolts and take out both parts of the blade.
Install a new or sharpened blade proceeding in the reverse
sequence.
Replace the other blades following the same procedure as for the
replacement of the first blade.
When reinstalling the blades, ensure that they are correctly fastened
and secured in place!
