7.9 CUTTER BLADES
A. Blade Inspection
1. Remove the ignition key before servicing the blades.
2. Tilt the mower deck and secure in place with the two
prop rods.
3. Check the blades for straightness by marking the tip
position of the blade on the inside of the deck. Then
rotate the opposite tip of the blade to the same
position. Compare the difference in the blade tip
track. If the track is more than 1/8 inch, the blade is
bent and should be replaced.
WARNING:
4. If a blade cutting edge is dull or nicked, it should be
sharpened. Remove the blades for sharpening. See
"Blade Replacement."
Do not attempt to straighten a bent blade, and
never weld a broken or cracked blade. Always
replace it with a new blade to assure safety.
Figure 7-8 Belt Tensioning
Never operate the cutter blades with the deck
in the raised position because it is hazardous.
