Mulching Blade Sharpening
1. Free the blade of any grease, dirt, or clippings prior
to sharpening.
2. Check the blades to make sure they are not bent or
cracked.
3. Remove the vertical platen by removing the two Allen bolts that attach it to the contact wheel
guard. By removing the platen, a large “slack” free belt area is created. Using a flexible back
belt or a narrow stiff back belt you will be able to use the slack area to sharpen the blade.
4. It is important to readjust the contact wheel guard to remove the pinch point created by
removing the platen.
5. The operator will freehand the desired angle.
6. After sharpening the first edge, use the slack area of the belt to remove any burrs that may
have been created in the sharpening procedure.
7. Move to the second edge and repeat the procedure.
8. Check the balance of the blade to ensure proper stock removal.
Rotary-Style Offset Flail Blade Sharpening
Depending on style of the blade, balancing the blade
maybe different than described in this manual. Most
rotary blades can be balanced using a simple balance-
style scale. Since there is no other way to check for balance due to the offset hole style of the
blades, use of a scale is to make sure that the blades are all equal in mass. Using a scale
allows you to make sure each blade weighs the same amount, keeping the blades in balance.
Start with the lightest blade and then sharpen the heavier blade, checking the blades for
balance.
•
Free the blade of any grease, dirt, or clippings prior to sharpening.
•
Check the blades to make sure they are not bent or cracked.
•
Attach the galvanized tubing to the worktable, using two button head screws and two keps
nuts. This changes the angle for the rotary-style blade to a factory recommended angle. As
with mower blades, it is recommended to move the blade in one direction only.
•
If the blade has deep chips, use the contact wheel to “face the blade”.
•
Move up on the contact wheel a couple of inches to the centerline and run the blade back
and forth several times to even the edge of the blade.
•
Rest the blade against the tubing and start the sharpening process.
•
Use only light inward pressure. The belt and speed of the belt will do all the work.
