Section 7
Charging rates between 3 and 50 amperes are satisfactory 
if  excessive  gassing  or  spewing  of  electrolyte  does  not 
occur  or  the  battery  does  not  feel  excessively  hot  (over 
125°F). If spewing or gassing occurs or the temperature 
exceeds  125°F,  the  charging  rate  must  be  reduced  or 
temporarily stopped to permit cooling.
B. JUMP STARTING
The booster battery must be a 12 volt type. If a 
1. 
vehicle is used for jump starting, it must have a 
negative ground system.
When connecting the jumper cables, connect the 
2. 
positive cable to the positive battery post, then 
connect the negative cable to the negative battery 
post.
CUTTER BLADES
7.8 
A. BLADE INSPECTION
Remove the ignition key before servicing the blades.
1. 
Raise the mower deck to the highest position. Place 
2. 
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.
Check the cutter blades for straightness. If the cutter 
3. 
blades appear bent, they will need to be replaced.
 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.
If a blade cutting edge is dull or nicked, it should be 
4. 
sharpened. Remove the blades for sharpening. See 
"Blade Replacement."
- NOTE -
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
- NOTE -
If possible, use a file to sharpen the blade. Using 
a wheel grinder may burn the blade.
- NOTE -
DO  NOT  sharpen  the  blades  beyond  1/3  of  the 
width of the blade. See Figure 7-3.
Sharpen the cutting edge at the same bevel as the 
1. 
original. See Figure 7-3. Sharpen only the top of the 
cutting edge to maintain sharpness.

Check the balance of the blade. If the blades are out

of balance, vibration and premature wear can occur. 
See your authorized Scag dealer for blade balancing 
or special tools, if you choose to balance your own 
blades.
