7.10 CUTTER BLADES

A. BLADE INSPECTION
1. Remove the ignition key before servicing the blades.
2. Raise the mower deck to the highest position. Place
the lanyard pin in the highest cutting height position
to prevent the cutter deck from falling.
WARNING
Always wear proper hand and eye protection when
working with cutter blades.
3. Check the cutter blades for straightness. If the cutter
blades appear bent, they will need to be replaced.
4. Check the cutter blades for wear. If any part of the
cutter blade is worn to 1/2 its original thickness,
replace the cutter blade.
WARNING
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.
5. Check the cutter blades for gouges. If there are
gouges on the top or bottom surfaces of the cutter
blade, replace the cutter blade.
6. If a blade cutting edge is dull or nicked, it should be
sharpened. Remove the blades for sharpening. See
"Blade Replacement."
Keep the blades sharp. Cutting with dull blades not
only yields a poor mowing job, but slows the cutting
speed of the mower and causes extra wear on the
engine and the blade drive by pulling hard.
B. BLADE SHARPENING
If possible, use a file to sharpen the blade. Using
a wheel grinder may burn the blade.
DO NOT sharpen the blades beyond 1/3 of the
width of the blade. See Figure 7-8.
1. Sharpen the cutting edge at the same bevel as the
original. See Figure 7-8. Sharpen only the top of the
cutting edge to maintain sharpness.
Do Not Cut In

2. Check the balance of the blade. If the blades are out
of balance, vibration and premature wear can occur.
The cutter blades should be balanced to 1-1/2 oz-in.
See your authorized Scag dealer for blade balancing
or special tools, if you choose to balance your own
blades.
C. BLADE REPLACEMENT
WARNING
Always wear proper hand and eye protection when
working with cutter blades.
1. Remove the ignition key before replacing the blades.
