8/2/2024 searching how to change a lawn mower blade. Young men take to a shop. Old school saves money. Thank you for making this video 15 years ago. Still needed.

[@mikesprau6149]

14 yrs later and still being viewed. Thank you, sir, from another happy viewer.

[@ElohiSilverEarthVentures]

Right that's pretty dang good for this old of a post. He's got some points in here that nobody else provides about tipping your lawn mower over

[@CharlesLeaverSouthAfrica]

Of all the various different blade changing videos that I watched this was the only one that warned about not filling the air filter with oil. Such an important thing to mention. Congrats on the great video :)

Every way I tilt fuel leaks

[@Wele12545]

What size socket wrench was that?

[@angelinh.5774]

@@bugsy74 use a baggie over the hole and screw the gas cap back on. Or mow it out of gas.

[@SaxJockey]

​@@angelinh.5774In order to change the blade, I put a bag under the cap on the tank (seen that method on another video). Also removed and stowed the plug lead. The bag worked fine, however, fuel started to drip from the carburettor. So I ended up draining the tank, pipe to carb, and carb bowl. The mower has always worked fine (also after changing the blade). Not sure why the leak occured; is it expected that fuel from the bowl would pass the diaphragm while the deck is on it's side (only)? The fuel leaked from somewhere on the carb, but did not flow into the foam air filter. No leaks evident on completion, fuel up and subsequent mowing.

[@sharptongue1]

That was one of the best blade removal videos I've seen. Your description of which lawnmowers can be tilted on their sides was very helpful -- and the first time I've heard it described as clearly, as well as your explanation as to why pull the whole spark plug, and not just remove the cap. Can't' wait to try the tip about clamping to remove the blade. Thanks.

[@kmdsby]

I am a 52 yr old woman and still can't believe I was able to change my blade with your help. And we even have the same mower. I had that same clamp too but until now I did not know what it was. I had to use a rubber mallet to bound the wrench because I forgot to squeeze it. Thanks great video I saved some money.

[@plamenplamenof3567]

Lightweight is good and what did I use it for it’s a lawnmower kzbin.infoUgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wwsCqk also recommend Yes it is lightweight so hence not as robust as our old one. But if you take care it does the job really well.

[@lancegoodthrust7819]

I have watched other videos but this one worked best for me. The vise-grip trick works so much better than trying to stuff a hunk of wood in there. Thanks.

[@davidtehr2993]

Thank you! From Perth, Western Australia. As an old 61yo DIY-challenged idiot, your simple "things to watch out for" is MOST informative. Again, thanks! (I'll now get a new air filter for our Rover lawnmower!)

[@sionehefa3458]

Excellent! Was stripping down an old discarded mower today for its parts and got stuck on the blade removal part and now I know AND you have also taught me about the importance of leaning a mower on the correct side. Many thanks.

[@robt6127]

14 years later and still helping people out from all ranges of DIY. I usually do mechanic work on my car so I know my way around but good tip about the spark plug and was not aware it matters what direction to tip the mower based on the air filter.

[@JoseMTamez]

Wow! 14 years and it helped me. The Visegrips was a great trick and worked great. Thank you sir!

[@nivenherrington]

Thanks for sharing this video. I was trying to use the vise grips to hold the blade in place while using a wrench on the nut. Who'd thunk you could just clamp it on the side of the mower to stop the blade. Doh! Feeling a little silly now. Blade was replaced with ease. Much appreciated.

[@stevethomas70]

The real helpful piece of info in the video is using the vice grips on the edge to act as a block so the blade can not turn. Amazing tip. Thanks.

[@grahamshave8405]

Great video - some really important points I wouldn't have known: particularly about which way to tilt! Thanks for this!

[@AlS.-kn3cq]

Just watch your video and I'm very impressed with how easy you make it look. But most of all what I liked is the fact that you put great emphasis on safety. Thank you for a great video.

[@rpwolfe72]

How easy he made it look? Lmao, it's literally one nut.

[@Kobe29261]

Brilliant - you not only showed how but what to know before you consider taking off a lawn mower blade. I've been tilting mine the wrong way all this time!

[@greenatom]

I have to watch this video every year!

[@tobyjack9608]

I knew there had to be a smart way to keep the blade from turning, thanks very much for the instruction. I wish I had watched your video before I turned the mower over on the wrong side. Yeah, lots of oil to clean out of the carburetor now... Everything about the mower needs cleaning or replacing, but hey, it was free :) And thanks to videos like this, I am figuring out how to hopefully get it operating like a good grass cutting mower should. Happy Spring!

[@tdeful3342]

Thank you for taking the time to make this video!

[@dmoogles]

Thank you, Mark!! I came here to find out which way to tilt the mower when removing the blade and you answered my question in seconds!! THANK YOU!! 👍👍 Great video!! 😁

[@AIainMConnachie]

Finally someone says the truth It depends on the configuration

[@jeligula]

Thank you for the advice, Mark. I have one of those Quattro's and almost tipped it the wrong way before I saw your video.

[@JusTimeSTL]

great job dude. thank u. stuff like this is what makes the internet good

[@RedEyeC]

Weedeater Series 300 - use a plastic (sandwich bag will work) to fit tightened under the gas cap to keep gas from leaking out - tilt towards oil dipstick end (not air filter).

[@leanng.6110]

Great video -very thorough, easy to understand, can see exactly what’s happening. thanks so much!!

[@ddk80]

Great Video! The only things I would recommend is if you decide to use a socket wrench to remove the lawn mower bolt use a 6 point socket to not damage/round off the bolt and use a little bit of anti-seize on the threads. The next time you decide to remove the bolt, the anti-seize will make the job a job a lot easier.

[@azgarogly]

That's great when your blade can be removed that easy. The mower I have to take apart now got some rust on it and the bolt is stuck completely. Not much I have succeeded so far to get it lose.

[@MiddyBlue65]

Yours has got to be the easiest so far that I've been watching all day. Thank you so much. And using the vice grip was very smart. I'm going to do the same. I think I may have tilted my mower the wrong way tho. Hope not. Thx again.

[@TheBitcoinBoomer327]

Thank you! This made the job really easy!!!

[@dghmusic]

Your video was well done. I had the blade off in minutes (soaked the bolt with penetrating oil for an hour prior), removed the motor and am waiting on my replacement.

[@clasof56]

hahhaha...just great...i watched several videos before i found yours. the vise grips worked great. i had tried and tried with wood and just could never do it on this battery mower but your tip moves it to the top of the list...thanks again. clas

[@RickInDorset]

Very well explained along with advisable tips. Many thanks! :)

[@jimbodee4043]

Needed to see how you stopped blade from rotating, I then used this method my self. Had a 20 year since last removed rusted but and blade. Thanks

[@ElloMyNameIsWalton]

Thanks for this good vid. You hit on all the important points, and it was clear and concise. QUICK TIP: To ensure you don't mar the paint finish when using the vise grips, clip a piece of rubber off your handy-dandy too-patched-up bike tire tube and put it on the outside edge of the deck. I personally never have to worry about that because I've never owned a new one. Mine are always wreck-decks, lol.

[@512JonesTube]

Awesome video! Of all the videos I watched this one was the most helpful and easiest to understand. Thanks!

[@Emotional2000]

Thanks for this video.... It was very informative and totally helped me out with taking off my lawn mower blade.... You have made me a very happy woman today by sharing this instructional video. Thanks again....

[@jesica9540]

Happy father’s day!

[@airheeddrone876]

Thanks for this clear and comprehensive video

[@drewpert0515]

Vice grips.. Genius! Thank you

[@smcal1able]

Best removal video with tips yet, and demonstration.

[@hopelessabandon]

Thank you so much. I managed to change the blade that I have asked my partner to sort for over a year 😂

[@wherehouseedm]

All the info needed. Very complete and concise

[@defenestrationfan]

Woah - thanks for the tip - I have a quatro and I would've dumped oil into the carb! Thank-you!!

[@jhh243]

Thanks again, a couple years later!

[@martynj-c4965]

I always wrap old rags around each end of the blade too and Wear welding gloves just in case. Good safety video though.

[@Kabeljauwsje]

Great tip. Merci from France...

[@joeroganjosh9333]

Very good demonstration. Before checking this out I'd already got the sponge air filter soaked in oil when turning the whole machine upside down, hey we are not all mechanics.

[@mariomelchor7547]

Thank you for sharing this video was a big help

[@demickdoug]

Thanks for your help! I got the blade off.

[@rickb3555]

Great idea to clamp the vice grips to the mower to block the blade. I've been struggling for years holding one end of the blade and trying to loosen the bolt.

[@cliveharrison6054]

This was a great help. the mole grips a great tip. many thanks

[@homesteader9]

This video saved the day as i had a frozen bolt and was unsure of which way to whack the hammer! Now I know! "In the direction of the cut!!! =)

[@styke7]

great video... all the little details make a big difference. thank you!

[@bethkurzawinski6]

Thank you so much it really helped

[@wheezypeezy639]

Vice grip trick worked perfectly thank you

[@dntlss]

I actually have a bolens with the foam filter and Quattro engine and you want to tilt it with the dipstick down,the carburetor is on the other side plus the foam filter so they wont get oil in them if you till it that way, made that mistake early on.

[@pbldrum]

I have a 13 yr old Craftsman B&S Gold Series mower w the 6.75 hp motor. My air filter is a combination of foam and paper. Is it okay to tilt the mower with the muffler side down? I've got most of the gas out and a plastic sandwich bag under the gas cap. I desperately need to change the very dull blade. Thanks

[@dorothymartin8557]

I tried to put the blade back on my 21" 140 Toro Recycler but I couldn't tighten it, it kept turning. I see there is a cog on the blade bolt, and there seem to be 2 slots in the shaft it goes onto. Do the cogs have to be placed into the slots in the shaft somehow?.or have I somehow ruined my lawnmower since I can't get the blade tight, it just keeps turning on the shaft and the shaft also keeps turning, as does the flywheel on top of the mower. I had hit something with the mower blade, and couldn't get it loose, but finally used a pipe on the wrench to get it off,.but now it just keeps turning when I try to tighten it back on and won't get tight.

[@Bonhamaniac]

Thank you so very much! Very Helpful! All better now. Mowing away. I appreciate all of the precautionary remarks. Well done. Again - Thanks!

[@tracyosborne854]

Good demo and safety tips are appreciated thanks.

[@evidence62er]

I tried this before watching this video, I was doing it all wrong. Thanks a ton

[@j.michaelwiiams1859]

Thanks for the help, Dad.

[@theguru83]

Superb video!! This was very helpful. Saved me a lot of time. Thanks a Ton!!!

[@karmaline]

Do you need add red or blue lock tite when you put on or just wrench it on tight as you can?

[@tuco86x]

Excellent knowledge

[@luissonoma6255]

Nice, thanks. You just took me out of a jam!

[@jhors7777]

Thank you for posting this helpful video.

[@ronmartinmhg2804]

I've got a problem removing the bolt as the head has been mutilated. What size is the bolt? I've been standing the mower on its front end with chocks to stop it rolling. Is there a risk of oil flowing where it shouldn't? And I don't mean on the ground. A good video and such a simple way to stop the blade revolving. Thanks.

[@user-jf2qf6yq7b]

I had another part fall out that the blade screws into. How do I get it back on?

[@carolfisher2930]

thanks so much. I've been struggling to remove the blade on my mower, to no avail.

[@SDsailor7]

Thank uou for the video. Very informative and interesting. Is it ok to use an impact wrench?

[@bwood6337]

Thanks that was super clear and helpful! Buuuut when putting the blade back on do you use anything like lock tight or just screw the bolt back in?

[@hassanshah9659]

Thanks, that's really helpful

[@TOMMYHAWK77]

This helped me greatly. Thank you so much!

[@juliocesarmorales7852]

Thanks for great tip have a great day

[@2Greenlid]

I would maybe add a piece of cardboard or buffer between the painted mower decal & vice grips if a newer mower so as not to scratch, great video thanks!

[@timrobinson6573]

Most people don't care if the paint on their mower is damaged. I know some very neurotic people with no lives care about that stuff but most people have more important things to worry about.

[@johnruthven3619]

Atco Viscount 19E - no bolt in center of blade - instead a flush hole - I think it is an Allen key (hex key) needed for flush blade fittings? Would be as well to know that there are many different bolts and fittings for a blade - easy if you can see a bolt but not if none visible

[@alejandroquijada3361]

Thank you dad.

[@nonoyd]

any tips on how to remove the bolt if it does not turn to loosen it? i only have a socket not like your wrench, but im not sure if it would help if i get a wrench like yours. i tried hammering it no luck.

[@wiley4ya]

Question, are some of the murray 22'' regular lawnmowers threaded different? As in the opposite of righty tighty, lefty loosey

[@justineast5380]

This was helpful i appreciate the video

[@Nottherealcasper]

Thank u so much 14 years later

I suck at this stuff. Thanks for your help.

[@echoman556]

I have a Poulan Pro PR500N21SH 21″ Gas Push Lawn Mower. What size wrench do I need? I have to go buy one.

[@jollymontube]

very helpful; thank you

[@normatither3023]

Adapter turns as I try to loosen bolt. How to I keep it from turning?

[@anthonys6140]

Very clear instructions Thanks

[@audreypepper5257]

How will you get a blade off a lawn mower where someone rounded corners off the hex bolt

[@Fladavenue]

Best video by far--- & I've just watched all of them!

[@qjarman7753]

Great tips thanks

[@mrhudah]

Great Video

[@dadbeardtv3350]

so now that I've put on my new blade I have a problem. Why is it that when i pull the start cord it fires up a little bit and then stops. When i go to check it the blade is loose and the screw has come undone. I've wrench the screw down tight but it still comes loose.

[@BIGPOPRL]

Great period of instruction! Thanks!

[@RiderNJack]

Nobody ever tells you WHAT SIZE WRENCH you need...

[@ushoys]

Some blade holding bolts are right hand thread so they have to be turned CLOCKWISE to undo them. i.e. Righty Loosey. But the manufacturers don’t tell you this so you have to figure which way to turn the bolt for yourself.

[@Cr8MyLuck]

Good video.

[@Matthew_Helbert]

this is very useful

[@RT-yh8pi]

Thank you sir! Surprisingly helpful for sure a seemingly easy procedure!
