 what's the people in mind right here coming to you with the video this time we are going to be replacing the broken and dull blade of my lawnmower the tools that we're going to be using for this are this arnold extension plug extractor thing the max power 21 inch blade it is a 21 lawnmower along with air filter and a spark plug that i also got from amazon similar to my previous videos this is not a sponsored video so i buy the stuff as is and i give my honest opinion the first thing i've done is i've tilted the lawnmower over with the oil side up and the air filter side up that way the fuel doesn't go my fuel and my lawnmower were very low so i don't have any risk of it going out but just to be on the safe side i did put a plastic bag on top and make sure to also disconnect the spark plug that way while you're rotating it doesn't automatically turn on in addition to that i'm going to be using this piece of lumber and putting it right next to the blade that way the blade doesn't turn all right just had to go a little bit more medieval with a hammer with a hammer and a wrench just knocked it off again lefty loosey righty tidy and now we're just coming right off now i can remove it by hand and that thing was tight really tight so that is it this is out i had to use a little bit of a wd-40 to get this going now that this is done this comes out as you can see this is the old blade the blade lines are perfectly but the edge is up gone it has lost a lot of metal as compared to the old blade this newer blade is slightly heavier which is good the way that i want to mount and again be careful this thing is a little bit sharp the way that i want to mount is the flange side down take a little bit of penetration fluid just push it in prevents the rust land it in and there you go start tightening it by hand and then take your wrench and start tightening it and for a good measure just bang it once and that's it that's it this is done now we're going to be straightening the lawn mower and replacing the air filter and also the spark plug to replace the air filter just take the top latch off this is the old air filter as you can see it is filthy it is absolutely fill of crud you'll get really bad gas mileage i did try to knock it off a little bit a couple of times but yeah this is done this is a brand new one all white all clear you can't even see light coming through this one so the light is coming around this one that's it very easy just push it in plug it in close the cover and snap it into place so the filter is on just disregard this or just toss it out there is no saving this now to change the spark plug just get the tool that you get from blows or home depot this is the one that i got it works take out the leading cord and the spark plug on this one is at an angle it's not completely straight it's a little bit tilted so take your socket thing plug it in once it connects take the pipe thingy that is there and again left to do the righty tidy and a little bit of push comes out and preferably do change these spark plugs on and the air filter frequently that way you don't end up overexerting the lawn mower and spoiling the engine so this is the old spark plug it's full of carbon this is a new one identical and this one has no carbon at all it's already pre-gapped so you don't have to worry about it just initially feed it by hand and again remember it is a little bit angled and tighten it take your socket thing that you have push it in and just give it a little bit of a tug don't break it because this is very delicate just push it in and that's it spark plugs again dispose of it carefully push the wire in you will hear the click and that's how you replace the blade and also take care of the air filter and the spark plug on your lawn mower as always like comment subscribe if you have any questions about this video or if you want me to provide additional details please feel free to let me know I'll be happy to help hi people take care bye
