Apparently, you need to do this way more often than I thought. First, drop that, that, cable, cable. Now, I should be able to just simply drag this out, but we all know how things go. This quick 30-second process give me the most annoying 4 hours of a project that's going to take me 7 days to finish. Welcome to Jackass. Psych, I'm him. All right, let's flip this thing over. Next, we just need to remove the blades. Nothing happens. The internet's not [snorts] real. Grandpappy told my pappy back in my day, son, a man had to answer for the wicked that he's done. Take all the rope in Texas, find a tall oak tree, round up all them bad boys, hang them high in the street. Shout out to Toby Keith. We got all the lawnmower blades off. Let me show you how to sharpen them and why. Got the shot. Clamp. Angle grinder with abrasive wheel. >> [snorts] >> You know, you really should be using a bench vise for this. Well, Mark from accounting, I don't have one. Sharp blade, dull blade. Yeah, I got that right. But, por qué? It matters. Let me show you. You probably didn't think you're going to get both a how to sharpen your lawn blades and how to be bilingual all in one lesson, but here you go, folks. I just learned this lesson from one of the lawn guys. Shout out, Chris. Whenever you cut your lawn, it should look like this. Nice clean cut, everything's nice and green. Whenever you have something like this, where it's torn out like this, starts getting yellow, and then it's green down below, what's happening is your blades are dull. So, whenever you're cutting your lawn, you should have a nice clean cut like this and uniformity in color. Now, if your lawn looks like this, it's jagged on top, you have yellowing on top, flares out, and the green goes below, your blades are dull. But, por qué that happened? Damn, I'm bilingual as hell. When you create a nice clean cut, it heals itself up like a scab and it keeps all the water out. Whenever you have abrasive roots, you have all these exposed straws, water sinks in and starts growing bacteria in here. What kind of bacteria? I don't know. It's just like the one people say you have toxins in your body. Name one toxin. I'm going to go sweat out my toxin. Yeah, which ones? The only toxin I can ever imagine is if you're possessed by a demon, but that's a whole different story. So, cut like this, don't cut like that. Oh, and they also said don't water it like every day. Do like every 3 to 4 days. So, let the roots get to the ground. And then if you have a miracle of good housekeeping, let's put them back on. Gator boots with a pimped out Gucci suit. Ain't got no time, but I stay fly. Can't pay my rent cuz all my money spent, but that's okay cuz I'm still fly. Well, fortunately that was completely uneventful. Let's slice and dice this lawn. Oh, I am happy with that cut. Okay, things. Bye.
