- This covers how you determine which way to turn the bolt, and the correct way to install the blade.
When I looked under this mower I realized the mistake, I didn't know there was a wrong way to do it until today. :-)
It's amazing the number of YT videos on how to remove the blades but fail to adequately explain the simple method to loosen turn towards the cutting edge. Thank you!
Right? 👍
This info just helped me. I've always had issues when loosening the blade nut, never really knowing which way I should be turning it on my different mowers over the years. Thank you.
Thanks. It applies to anything with a shaft and a bolt in the end. 🙂
Thank you so much for your help!! Not only, thank you for teaching me how to deal with the problem and about tools I can get to do what I tried. Absolutely, you are a teacher. Thank you !!!
I am glad it worked! I love hearing that I helped someone through a problem. 😁
1:02: Great tip on determining left or right handed bolt threads for the bolt removal.
That's one of those things that always gets people. Different motors can turn different directions. It applies to everything, not just mowers 👍
Thank you! Needed this info today
I hope it made it easy. 👍
Should have tuned the blade a bit to to show which direction you meant instead bolt turns this way to and that way to non cutting side etc. That was the only thing that confused me a bit on your explanation, thanks for the video.
Guilty. I was still learning camera angles and what to talk about when I made that one. It was one of my first videos.😁
It was still a helpful video to learn about the connector. @GuysPlayingWithTools
Thanks. I like "you shoulda" comments. They show me what people like to see. Of course, back then, I was still learning that. 😁
knobs act as spear pins also...if blade hits a pipe or similar the knobs will shear off and blade spins free protecting engine shaft from breaking.
I have seen that happen too. I wouldn't think it would work, but every and then, I get one with the pins sheared and a torn up blade.... and a perfectly good crank. .
happened to in-laws...knobs are bit softer and sort of "pressed" into place ready to sear.@@GuysPlayingWithTools
@kam75 When I get a motor with a rattle, it's the fit rest thing I check
Great help thanks.
😁👍
Hi! I have a question. I ran into something hard with my lawnmower and I thought the blade was busted. When I turned it and checked, noticed that square at the end of the shaft and the blade was no longer on the pins, and the pins are busted, they no longer hold the blade.
I tried to remove the blade to see if that square can be replaced, but i cannot remove it, it turns over the square regardless how hard I tried to clamp them together. Is there a trick on how to take the blade off, other than clamping tools?
Thank you so much!!
Actually it is not the blade turning
Sorry. I stopped the blade with a clamp. The square is turning when I try to take the bolt out
Good Morning. I have to say, I thought "Yikers" when I read this, but all is not lost(probably)
This will be wordy but I want to go over everything as much as possible and tell you what I wish people told me when I was getting started.
There is a chance you bent the crankshaft, and if that's the case, I don't recommend trying to straighten it out because the internals of the motor may have also had a bad afternoon. Rotate the blade and look for any indication it's out of alignment on the center bolt, if it seems to be rotating on the center axis, it's saveable!
In that case this isn't as hard to fix as you may think. There is a blade adapter between the blade and the crankshaft and that's the part with the pins that you bolt the blade to. Take the center bolt out and it should come off pretty easily, it might need a puller since it took a hit, most auto stores will loan you one for free.
You can get a replacement blade adapter online or at your local parts store pretty cheap, They are usually between $15 and $20. With the right tools and a little luck it's a 5 minute job. *Be careful about which way the nut turns!* It might be "left handed" I have a video on how to figure it out easily, czcams.com/video/iU876-bgQHo/video.html
Let me know if you need anything else, and how it comes out!
Thank you very much for your reply. I also thought shaft might be bent. The bolt moves with the square, and one of the pins is more worn than the other, which tells me shaft might have a bit of a bent. I left it with a wd40 soak and will try again to clamp the square to the blade and try one more time to take the bolt out. If not, I will put it in the car and take it in. Also might have to check on warranty as it’s got 4 years. Keep my fingers crossed, bought it because it has a Briggs and Stratton engine ☹️
Will let you the outcome.
Thanks a lot!

Don't worry too much about the uneven pin wear, it's odd but not terribly unusual. If you don't have one, beg, borrow, buy or steal a battery impact gun. I bought mine specifically because I had a blade that I couldn't get off and I was tired of dragging out air hoses to use the big impact. It has never failed to take blades off with nearly no effort, you usually don't even have to hold the blade. The day you try it I will get a comment about how easy it was. 😀
If you can't borrow one, consider that the cost to take it into a shop will subsidize a new one. FYI, the one you see me using in the videos is a 3/8 Milwaukee M12 impact and it works like a charm. It's more work to walk over to the mower than it is to take the blade off.
(Make sure you are trying to turn it the right direction, it's not obvious.)
That bolt is not coming out whatever I tried, used 4 clamps. Two on the square and blade and two on the edge or the mower to keep the blade. Shaft is for sure bent.
Lucky me I have a tractor mower and this one is for small areas. Will take it in, not sure the warranty will cover.
Thanks again!
What if there are no 'knobs' that fits in the wholes of the blade are gone? :(
If the blade adapter pins are missing or worn all the way down, you should replace it. There are a few different styles, so make sure you match yours.
Best videos
Thanks 😁
What kind of winch is that
It's a 3/8 air ratchet. Batteries have come a long way since then though, I switched off to a battery impact about a year ago
Looks like that blade was put on wrong. You fix the bolts lining up but there was no washers like there is on my Craftsman mower there on other Craftsman mowers there is a plate that comes off with it has another lock in washer and my bolt was too long. Wouldn't go in seem like threads were getting caught almost stripped out I got a new bolt n blade I can't find a video of the actual mower or what size of socket people were talking about 3/8 to 1/2 in
They are definitely different from one to the next, this is correct for this one but you are 101% right, some have additional washers and the bolt won't tighten without them. One of the downsides of making videos about things like this is that I can't cover every situation out there. What's the model # on yours? I will keep my eyes open and if I have one(or when I get one) I will touch on the differences in a video.
My bolts not moving.. any tips?
Sure, I need to start with questions though, Are you moving towards the cutting edge of the blade, and what tool are you using? any tool with the word impact in it will make it a lot easier 🙂
@@GuysPlayingWithTools sorted borrowed neighbors impact drill 😂😂😂
@alandrummond5890 We better hurry then before he sees it's sorta missing. Lol
1. Make sure you are turning towards the sharp side of the blade. The blade could be backwards, so it's also like holding the bolt still while the motor is running.
2. If it's not stripped, make sure the impact is turned all the way up. Mine won't pull a tough one unless it's set to "kill"
3. If it is, and it's not stripped, you need more power. Take it to your favorite parts store, they will usually lend you a bigger impact or even walk outside and do it for you.
4. If it's stripped, there are a few ways to go. My preferred way is to grind the head off, and if there is anything to grab, it will usually be finger tight. If not, drill a hole in the center of the bolt and use a reverse twist bolt removal tool and it will hop out pretty easy. The auto parts stores are usually good about loaning out this kinda tool, O'Reillys has always been good about it for me.
What tool is that?
I used a 3/8 air impact on this one. Since then I have switched out to al battery tools, a 3/8 or better battery impact works just as well 👍
Forgive my ignorance but what tool did you use?
That's a good question. I used a 3/8 impact air tool in this video, but that was a while ago. Battery impact guns have improved greatly since then, and I use a Milwaukee 3/8 impact gun for the same job now.
You could use a standard socket set, but it's a LOT easier and faster with your favorite impact tool.
Thx!
👍 I hope it helps
What’s the tool you use?
When I did this video, I used a 3/8 air impact. I switched off to a Milwaukee 3/8 battery impact since then to get rid of dragging air hoses around. 🙂
many times shaft rips those places off clean than what
Do you mean the little pins that stick out of the part you bolt the blade to(the blade adapter)?
If so, it's also replaceable, and they are usually pretty cheap.
Where is the torque wrench?
While an impact wrench isn't as accurate as a torque wrench, it's the tool everybody uses for blades, but nobody admits it. If you were to finger tighten a single bolt blade, the rotation of the mower would immediately tighten it. I wouldn't trust it that way though. 👍
good vid thanks - right to the point with no bs
Thanks, It's a simple problem. It needed a simple video. 🙂
Jee wiz yall! I don’t even have the extremely cool un bolting tool for the main bolt that holds the blade in place.. but it would help me tremendously if anyone could give suggestions on how to loosen the bolt to a chick with a hand held wrench 😂..
My gut is saying WD-40
I retired that air ratchet in favor of a battery impact gun a year or so ago. If you have someone that can lend you a battery impact(3/8 works great), it will spin right off. If not, take it to O'Reillys or Autozone and they will happily loosen it for you for free 👍
Use the wrench with a long pipe for leverage.
@@marc7491 A breaker bar, or pipe, works too.
Good
Thanks, I hope it helps👍
lefty lucy and righty tighty...get it straight
🤣That's true for at least 90% of them!
Always wear gloves and turn towards the sharp side of the blade and it's the right way. Every now and then I see one that turns the other way.
I yko
Very interesting, thank you!
I hope it helps. 👍
