You’ll find useful resources on this page, tips, links to tools, parts and supplies required to complete your repair.
An blunt blade will cause a ton of grass problems, but the most noticeable is lawn damage. Old blades tear the grass instead of cutting clean, torn grass leads to excessive moisture loss and yellowing of the lawn. In addition a blunt blade causes you and the mower to work harder.
A blade should be sharpened at least once per season and in this video we’ll do just that. We’ll sharpen the blade on the mower and off and you’ll understand when you can do both.
Tools & Parts
To nail this procedure you may need the following tools, parts and supplies.
Ratchet Tool Set
Before we can do anything, we'll need tools. I've selected this set as I own some Craftsman tools and while I have worn some out, they did do a lot of work. So I expect this set will last the occasional user quite a long time.
This set carries both metric and standard sockets and that's important, because some mowers will have both type of fastener sizes. Set includes spark plug sockets. Picture links to Amazon.com
Teng 1/2 Torque wrench, fantastic tool I use it every day and mine is still going strong. A torque wrench is advised for tightening components such as flywheel nuts and blades. The torque spec of these components is very important. Picture links to Amazon.com
If you are considering buying a torque wrench, definitely check out my review of Teng torque wrench.
