Hi, my name is Peter Gutwein and today we’re talking about doing some basic lawnmower, minor repairs to your walk behind mower here. Now that we’ve taken the blade off and we sharpened it, we’re going to talk about putting it on. Something that I’d like to do before I put on the blade is to clean up the deck. Grass builds up in there from mowing your lawn wet or your kids left the sprinkler on or whatever and so what you want to do is you want to clean all that stuff out and it’s kind of an enemy to your mower because you need a lot of air flow in there to bring up the grass to cut it and so all that dirt and old grass and stuff just kind of blocks that air flow. So we’re going to go ahead and use a basic gasket scraper here, you can pick one of these up anywhere but you can use a screwdriver or whatever, anything that’s easy. Then you just give it a good scrape, get out all the major chunks, you don’t have to everything about the wax on the underside. You can see there’s a lot of stuff on this one, it hasn’t been done for a while, there you go. Okay, now we can and reinstall our blade, what you want to do is you want to make sure that the beveled edge is up or towards the mower on this one. The reason I’ve seen a lot of poorly cutting mowers that the blade was installed backwards. So you go ahead and throw it on there, line up all the holes, the way it came off and line up the bolt, just give it a good crank. Make sure it’s nice and tight and the other thing you might want to do while you’re down there is make sure that these engine mountain bolts are nice and snug sometimes they can loosen up on you and these look in good shape, everything is nice and tight. So that’s how you would clean out a deck and put your blade back on.
