Always Start Mowing with Sharp Blades
A sharp blade cuts cleanly and without tearing or shredding
the grass blades like a dull blade. Tearing and shredding
causes the grass to turn brown at the edges which impairs
growth and increases susceptibility to diseases. Make sure
blade is in good condition and a full sail is present.
Check Condition of Deck
Make sure that the cutting chambers are in good condition.
Straighten any bends in the chamber components to ensure
the correct blade tip/chamber clearance.
After Operating
To ensure optimum performance, clean the underside of
mower housing. If you allow residue to build up in mower
housing, cutting performance will decrease.
Transport
Move the Enable/Disable switch to the Disable position and
raise the cutting decks to the transport position. Move the
Mow/Transport lever to the transport position. Be careful
when driving between objects so you do not accidentally
damage the machine or cutting decks. Use extra care when
operating the machine on slopes. Drive slowly and avoid
sharp turns on slopes to prevent roll overs. Lower the cutting
decks when going downhill for steering control.
