Motor Power Capacity 

If you are using a motor with power grinding wheels, go for a motor with higher capacity as it will perform heavy chores without any resistance. Engines mostly come with a mentioned power capacity, i.e., ½ HP or ¼ HP. I will recommend you to go for ½ HP.

Spinning Speed Capacity 

Higher the spinning speed better the performance of the grinding wheel. Grinding wheels come with 1500RPM or 1750RPM. Keep 1750RPM on your preference list if you want high-end performance.

Portability and Compatibility 

Portability is a must thing to check before buying anything. If you can not carry a machine efficiently, then operating it would be even more difficult. So, go for a blade of 5 to 6 inches that can be easily handled.

Its angle defines the compatibility of a grinding wheel. Select the blade sharpener, which has a more compatible angle. Angles can be offered like 30 or 40 degrees, so choose yourself which one is appropriate.

Buildup Material Quality

Changing a lawnmower is not that easy, and that is why you need to have a grinding wheel for keeping your blades’ sharpness alive. Do not compromise over its material. The best one to have a grinding wheel is of carbide material.

  • Place the blade on the table and check that must be tightened
  • Clean the blades thoroughly
  • Prepare the angle grinder now
  • Run the angle grinder across the edges

4. How to sharpen lawn mower blades with a grinder?

  • Remove the lawnmower blade.
  • Maintain the angle of grinding.
  • Make the light passes across the blade with the grinder.
  • Grind the metal with the same capacity from both edges to keep it balanced.

5. How sharp should a lawnmower blade be? 

A lawnmower blade should be sharp enough to give a proper grinding finish. It should be aggressively tapered. Keep in mind that it should not be sharp as a razor’s edge because this cuts the grass unproductively. With sharpness, it must be safe that you can touch the blade without getting any injury. Lawnmower blades that are too sharp to resist, get dull in a short period of usage. If you use your lawnmower in your home only, it must be sharpened once a year. But if you use it more often or professionally, then it needs to be sharpened frequently.
