 Mower Blade Tech Tips from J. Thomas- Measure your blade's length diagonally from cutting tip to cutting tip. For mulching blades, use the back side of the blade for ease of measurement.  - Replace blades when large nick(s) appear or when lift edge is noticeably worn. - Sharpen blades with a rotary blade grinder every 10-20 hours or when you see nicks or an eroded cutting edge. - Sharpen the beveled edges of the blade. - Care should be taken to keep the same angle of the cutting surface. - When sharpening, grind enough material to remove any nicks and to sharpen the blade – do not remove more than 3/8" of material from the blade. If more than 3/8" of material is removed, the blade should be discarded. - Blades should be balanced using a mechanical balancer. Unbalanced blades will cause vibrations leading to premature spindle bearing failure. |
