Checking and Replacing Mower Blade
WARNING
To avoid serious injury:
• Be sure to stop the engine and remove the key.
• Blades may be sharp. When you handle blades, wear heavy
gloves or wrap end of blade with a rag.
Before checking or replacing the blade, wipe grass and mud off
the top and inside of the mower. Especially clean up the inside of
the belt cover, because otherwise the belt life will be reduced.
 Checking Blade
1. The blade cutting edges should be kept sharp at all times.
Sharpen the cutting edges, if they resemble blade (b). Replace
the blades if they appear similar to blade (c).
 Replacing Blade
1. Remove the mower deck from the machine and turn it over to
expose the blades (4).
2. Wedge a block of wood (1) between the blade (4) and mower
housing as illustrated.
3. The blade bolt (2) has right hand threads, turn counterclockwise
to loosen.
The blade bolt (2) has left hand threads, turn clockwise to
loosen.
4. To sharpen the blades yourself, clamp the blade securely in a
vise.
Use a large mill file and file along the original bevel until sharp.
5. To check the blade for balance, place a small rod though the
centre hole. If the blade is not balanced, file the heavy side of
the blade until balance is achieved.
6. To attach blades (4), be sure to install the 2 cup washers (5)
between the blade (4) and bolt (2) head.
IMPORTANT
• Use the proper size box or socket wrench to tighten or
loosen the blade mounting bolt.
NOTE
• Make sure that the cup washer is not flattened out or worn;
this may cause blade to slip excessively. Replace the 2 cup
washers if either is damaged.
