Will Kelly shows how to replace a Stihl edger blade, including spotting when it's worn short and using a screwdriver or pliers to lock it in place. The mounting bolt is reverse-threaded, so it turns the opposite way from a normal bolt. He also demonstrates how to bow the edger away from you when the blade gets low to keep cutting cleanly.
This edger blade needs to be replaced. This is about the size that it needs to be when you need to replace it. I see a lot of people replacing this early, so I'm going to teach you how to edge when this thing is low. Most of the time you can go directly down, the wheel needs to be on the concrete, and it gives you a nice edge. When it's really low like that or shorter, you have to kind of bow— you gotta bow the edger out away from you, okay, to get a nice clean cut to where it's still rubbing along the concrete. Now I don't have a screwdriver right now, but if you look very closely here, there's a circle. If you spin this, it will line up to a hole that you can stick a skinny screwdriver in so that way this thing doesn't spin when you're trying to get it off. But in this scenario, I'm just going to grab it with pliers to stop it from spinning, and then I'm going to use our tool. It's a reverse thread, which means you actually have to, as if you're tightening it, twist it to where it's almost getting tightened to actually get it off. Alright, so this is what it should look like when you need to replace it. I'm gonna go ahead and put a halfway used blade on. This is halfway used, it still has life on it. We're gonna go to put our piece back on and we're gonna put our bolt. Now remember, it has to go opposite, it's a reverse thread on this due to the way that it actually spins. Also going to grab it with our pliers.
