INSPECTING BLADES______________________________________________________

1. Every 50 hours of operation or whenever mower is
removed from tractor, carefully examine the blades to
make sure they are in good operating condition.
Blades showing any bends (G), grooves (H) or
cracks (J) must be replaced.
!
CAUTION
Use care when checking blades to avoid pinching hands
and fingers between blade ends.
!
WARNING
Never attempt to straighten, weld or repair a damaged
blade. Always replace a damaged blade.
2. Any of the above conditions can cause a piece of
the blade to break away and be hurled from the
mower; causing very serious injury to bystanders or
property damage.
3. A bent blade could have a microscopic crack (G)
that can grow and allow a piece of the blade to
break. Bent blades will also create vibration and
other stress on the machinery.
4. Dust or sand particles can wear a dangerous groove
in the blade (H) between the air vanes and the flat
portion of the blade that will rapidly grow and
produce a crack (J), permitting a piece of the vane
to break off.
