I really can't thank you enough for this. I was thinking of selling my riding mower because it was just impossible for me to get the blades off, I thought I couldn't maintain it on my own. Last time I did it 3 years ago with a normal socket wrench and a pressure lock jammed into the deck, I almost broke my hands doing it. I had to make my own wood block from cutting 3 pieces of 2x4 and screwing them together. I got a breaker bar and already had a mower jack. It still took a bit of strength, but worked like a charm. You didn't just help me change my blades, you taught me that with the right tools and technique I can have confidence in myself. Thank you.
That's excellent! Thanks for the nice comment. Good job figuring it out. We've all received tips & tricks at one time or another so I'm glad I was able to pass along one of those to you!
I tried your procedure and found your blade removal was excellent. I appreciate your time saving repair. Consider a procedure on how to replace a deck nose roller especially on a craftsman 20 hp riding lawn mower.
😁👍
Didn't mention the blade has a top and a bottom. Make sure the top of the new blade is facing up and not down!
yes! the new blades I got have an imprint on one side that said "grass side".
@@pumm3l46 Some blades may also be "reversible", meaning you flip them over for a fresh cutting edge and only have to sharpen them half as often.
What if they don’t have that imprint?
WOW! Thank you - I have never changed a blade on a riding mower. I was concerned about all the work but you just made me believe I CAN DO THIS!!
Yes, you sure can! Just be aware that you'll want a long ratchet, preferably a breaker bar, to make it easier to get that nut off. It takes some muscle but the longer the breaker bar, the easier it is.
Good video…. I clamp a big c clamp on the side of the deck. That prevents the blade from turning. :)
Thanks. Good idea on the C-clamp!
Sometimes it is not that easy. The nuts are welded on sometimes and need an impact drill gun to remove the bolts. Ramps always help too! But I get your video on trying to do it the faster way!
Thank you so much!!! I was fighting with the seat belt for several minutes until I watched this video. This was super easy!!! Thank you so much!!
Good deal! I know you meant to leave this comment on a different video but it's all good!
Did you happen to mean the drive belt? That’s what I have been struggling with and now I know I don’t even need to mess with it! 😂
My older Craftsman, I would remove the belt, a few pins, and pull the deck off to work on it…
Thanks for the tips. I did use ramps because I have them and it saved a few curse words. I also used a C clamp to hold the wood in place. It worked well for me.
Good deal. Thanks for the comment 👍
I was about to take the whole deck off, thank you so much for this!
YW!
Thank You - the video you have shown will assist many a riding mower owner many hours of head ache. I followed your procedures and let me tell you it works. The one thing I had to purchase was a torque wrench to reach the flange nut holding the blade and ofcourse a new blade. While I was a it I also changed the other, older blade! Bravo!
Great! I'm glad this was useful to you!
My is a 2004 craftsman dyt 4000 it has a 9/16 bolt . the blade has a 5 point pattern I use a impact wrench no need for the block of wood. just raised the deck and back on to car ramps
Looks good though you could probably put something under the front wheels to give ypu more room. I am just about to change mine for the first time. I bought a cheap lawn tractor jack and a device to hold the blade. I don't know how I did it, but one of my blades is bent 25 degrees downward at the end of the blade.
Finding a good chunk of wood to wedge in there to loosen the bolt was the hardest part, Have a breaker bar handy, other than that its a piece of cake. Raising the front the mower up on jack-stands helped me get up in there.
👍
Thank you! Was getting ready for this to be way more involved.
Glad this made it easy for you!
Great video Bro, I was thinking the same thing using a breaker bar and socket. Great minds think alike! Keep up the good work dude!!!!
Thanks! Appreciate the nice compliment!!!
@@FixEverythingYourself Beats taking the deck off for sure👍
Or in place of wood an attached vise grip to the edge of the housing will stop the rotation of the blade. All blades rotate counterclockwise, so be sure the leading edge is the cutting edge so the blade won’t be upside down.
Thank you, sir, for the video. I have some Lawnmower, and I'd needed to do the some 👍 👌
Thanks for the feedback
How about disconnecting spark plug
Great video. Changing blades today thanks for making it easier.
You're welcome!
So like how do you know how much torque you applied to that nut to make sure the blade doesn't fly off at running speeds?
The driver obviously doesn't care about anyone else's ankles but like also some people will disengage the seat switch so the mower doesn't turn off when they get out of seat to pick up some twigs....
Spec is 70-90 ft-lbs
Yes, I know that. How do you know your wrench is achieving 70 - 90 ft lbs? A breaker bar doesn't click at any ft lbs so how do you know that it has achieved the peculiar spec which you mentioned?
The entire deck is moving which would rob some of the torque. Wouldn't a torque wrench be a better option?
Correct, without a torque wrench you won't know the exact torque. That said, you can estimate how much torque you're applying by multiplying the length of your breaker bar by how much force you estimate you're applying.
While that's obviously not very exact, this installation requires the nut to be firmly in place, so what's important is to make it nice and tight. Keep in mind that many people don't own a torque wrench (I do) and have been changing their blades for years with no problems. So as long as you make it nice and tight, it'll be fine.
Sir I just have exact mower bough it used, but seller had no manual. My question is - What oil filter and oil I should use? TIA
The Briggs manual says the oil filter number is 492932. Also says to use SAE 30 oil. Takes about 48 ounces.
@@FixEverythingYourself Thank you!
Thanks for posting this. You just saved me a bunch of time. 👑😎👍
Awesome!
didn't say which way the blade goes. Does the wings go up or down & It's easier taking the deck off if you down have your long breaker bar...
What size socket wrench to prey the blade? I have MTD 420/38 ride on mower
Can i do this while the tractor is running? My wife thought it would be easier
Couldn't hurt...
yes she's right, check to see if she raised your life ins though
Great Vid. Simple and to the point.
Thanks!
Thanks so much . Praying for God to reward you
👍
is that a 3/8 or 1/2 inch breaker bar?
1/2"
Thank you last time I changed the blade I put the lawnmower on its side and it gas or oil flooded the engine. Is there a safe easy way to raise the lawnmower off the ground about a foot without having to buy anything special?
Some people make some ramps using several pieces of wood stacked on top of each other, probably screwed together. You'll just have to improvise with something. Sorry I don't have a better suggestion.
If you have a steel bumper bolted to the front of your frame, you can use that to pick up the front end, then with your foot slide a sturdy milk crate under each front tire. I have an old GT6000 & that's what I do.
What socket size
Are both blades RH threads? I started on driver side and with a breaker bar twice as long as yours and the nut barely moves with wood locking the blade. This is screaming reverse thread or at least "something ain't right"
Mine both spun in the direction I showed on the one video. Perhaps your blades spin a different direction. If so, it would make sense for the threads to be reversed to prevent the nut from loosening. See if the pitch angle (which way the cutting edge of the blade leans as it spins) is opposite mine. If so, yours is reverse from mine.
I have the same mower. Is counter clockwise toward the front or back of the mower?
If you're on the left side of the mower with the breaker bar (wrench) sticking out the left side like I am in the video, counterclockwise is pushing that bar toward the front of the tractor.
great tutorial, but one lil thing he left out. If this is the first time you're changing the factory blades, do not next those bolts to go off quietly into the night. I replaced my fubar'd blades today. It took a 2 foot breaker bar AND a 6 foot piece of leftover chainlink fence post pipe for a lever to convince it to let go. Lotsa daddy fixin-the-car language, but it came off
👍😄
I have a troybuilt pony. Any guess how to keep the nut still? the block technique doesnt work as something inside spins with the nut. thanks
Sounds like you'll need an impact gun while still holding the blade with a wooden block. I don't know what the exact problem is but the intermittent impacts from the gun should help the nut break free. Otherwise, I'd have to see it to have a better suggestion. Good luck.
can you bring the blade back to craftsman as part of their broken tool replacement guarantee?
Hmm... I've been wrong before but I'm guessing that a consumable part like a mower blade wouldn't be covered. But I've never asked.
Does the new replacement blade come sharpened already?
Yes
Great advice it worked at the first try ✌🏽💪🏽🏆
🙂👍
Id be afraid that i wouldn’t be able get that bolt loose! So i need to determine size of bolt, then purchase a breaker bar, remove blade, then order the new blade (to ensure that u order the right blade).
Just tried this today, prepare spending 10 minutes in finding the right cut of wood....for one side and another for the other.
If you can find the right pieces then ya sure but half way through this process I wished I would have just pulled 4 pins and got it over with lol ...
Is 15/16th pretty common? I had a 3/4 that was too small today. I have a 2003 huskee.
I'm not sure how common it is. It's a standard size, of course, but not sure how many tractor brands use it at this location.
It wasn't in my standard socket set. Or at least I couldn't find it. I had to buy a 15/16th separately.
So, I got the bolt loosened but it will not come off. It continues to just spin. Any suggestions?
Hmmm, that's odd. I'm sure you've done this but I'd pry down harder on the blade near the center to help get the bolt out. Perhaps there's some gunk at the edge of the hole preventing it from coming out? Or try gently prying down on the head of the bolt with a pry bar. If that doesn't work, try prying down on the bolt while simultaneously loosening it. The bolt definitely has to come out so probably just something minor going on....
The block of wood I'm using keeps the spindle from turning by stopping the blade. That's the key: wedging the blade (with any kind of wood) such that it won't turn and you can loosen the bolt.
@@FixEverythingYourself yeah, I blocked the blade but the bolt still spins.
Wow, very weird. Are there any holes through the spindle where you could stick a large screwdriver (or similar) through there and wedge the other end of the screwdriver against something firm? Then the screwdriver would keep the pulley from spinning? Sorry if you've already thought of or tried these things; just wanting to be thorough if you haven't.
Otherwise, you may have to go the long route of taking the deck off so you can get better access to the spindle/pulley and keep it from turning.
How tight with that bolt to hold the blade please??
On mine, 70-90 ft-lbs. Basically, really tight.
Very helpful thank you for sharing.
YW!
Vice grips and a ratchet every time. Except this fucking thing. Thank you, dear god you saved me a deck removal or 250 dollars.
Great!
Excellent video. Thank you so much.
Thank you!
what do u do when the bolts and blades are rusty from setting all winter and dont have the strength to bust them loose i have a bad back
You can spray penetrating oil (that's the name) on it. You can get that at Walmart or any hardware store. Let that sit an hour or overnight and should be a lot easier to break free. You could also try the same thing with WD-40 but penetrating oil is better for this.
do not use wd40 for sure, get some kroil, the aero kroil is best because it comes in spray can, the antique car builders been using it forever and it is the best period. hard to find sometimes but it can be ordered. you will not believe how this stuff works.
@jimmieroan9881 👍
I've found using a c clamp on the side of the deck works much better. Also if you don't have car ramps( the best), at least drive the side you are working on up on to some 2×6's to give yourself some more room
👍
You could have used the jack behind you , jack it up in the front a foot or so, put a jack stand under it, and away you go. That's how I do it.
He also could have said which end faces the deck and which end faces the ground.
Yes .Remember with Viking twin deck there is a right and left blade and the pair I bought had nothing written on them……….so if you have the old ones discarded there is no chance of comparing them and you can end up with a left on right etc .Of course you can work it out on the rotation of the pulley and comparison with the cutting edge …..but Viking why not stamp left and right and grass side on your blades …I got caught had to take them off again .Won’t be dealing with Viking again .
Excelent video!
Thanks
Thanks!
Keep it simple thank you
🙂👍
Glad I found your video. I have the exact lawnmower and I'm removing my blades for sharpening and wasn't sure if it would be reverse threaded or not.
Excellent!
@@FixEverythingYourself But at 1:30 the indication is that it must be turned counterclockwise, but it appears to be going clockwise. Can you clear this up? Just don't want to strip the threads.
It's definitely counterclockwise when viewed from underneath the nut (i.e., looking at the nut from the direction of the wrench).
@@Gravyballs2011 that’s counterclockwise.
Can you make one for changing oil
Now what do ya do if the bolt spins with the nut??
Is the blade spinning at the same time, or just the center bolt? Normally, the only reason that would spin is if the blade isn't being kept stationary.
Socket Size ?
15/16" on mine
What size socket?
15/16", I believe.
Good Stuff. Quick and Easy.
Thanks!
nice video dude!
Thanks! 👍
Thanks i didn't know wha size socket I needed. All mine are too small. Got to make Lowes run.
Good. Or try Harbor Freight for cheap tools like that
thanks so much! very helpful
You're welcome!
Thank you sooo much!!!!
YW!
I guess they don’t make ramps for this kind of thing?
They do, or you can make ramps yourself.
Great video, can you give me the blade part number thanx
Here's a link to the exact ones I bought for this tractor: amzn.to/3rweWMZ
Part number is 490-110-M110
Thank you
If you wanna get a good cut but your blades are dull instead of replacing them just sharpen them if they are good or get them sharpened by a pro if you can’t tell if your blades are bad also a tip to who is watching these videos on how to replace your blades only replace them if they are bad to tell if they are bad is if they are less than 1.5 in wide
Money saving tip. Unless you have an extensive socket collection, most socket sets don't have the 15/16" socket. Pawn shops often have bins full of random sizes of sockets, usually for fifty cents to a dollar apiece. Go ahead and spend the 4 minutes digging thru the bin and get yourself one for cheap.
👍
People always overtighten those bolts. One time I had to use 6 foot pipe on my breaker bar.
it worked thx.
👍🙂
Thank you
👍👍
Well shit! And here I thought I was gonna have to put my mower up on blocks.
No torque?
Lots of torque. 70-90 ft-lbs
Old school, tight as you can get it, like when the blade starts eating the block...LOL,but serious. 110 ft lbs opn your TORKER
thanks!
👍🙂
Did mention to pull spark plug wire first for safety? :)
This is common sense and shouldn't have to be mentioned in a how to video.
This is like saying you should remove the firing pin after making sure a weapon is clear just to be safe to handle lol. Just take the key out.
@@stuartlittle69420 I dissemble my entire tractor……..just to be safe.
We would also assume the switch was off, nobody is in the seat, and any of the other built-in safety switches have not been manually bypassed..
Youre telling me for 40 years ive been doing it wrong?? Thank you
🙂 Nah, not wrong, you just found a faster way!
First things first. pull your spark plug wire off the plug, or remove the neutral cable on your battery. You don't want to risk starting this thing by accident by rotating the blades. Freak accidents to happen...
Easier to tip it diagonally with a couple of sticks of wood and make sure it's not going to fall on you. Remove the spark plug wire. 2x4 piece to stop the blade and then large crescent wrench to break it loose. If first you don't succeed, add WD 40.
Remove blades after breaking loose, tighten with the 2x4 and lower back down. Your blades are now installed. If you have a mower with two blades, it's recommended to change both of them at the same time otherwise they may be out of balance.
Now what you've done is tipped the oil up into the motor more than the mower likes. If you're going to replace the spark plug, and oil, this isn't a great problem.
You're never going to get down on the ground like that to change a lawnmower blade, face it.
If you're referring to a walk-behind mower, I agree with you. Otherwise, the way I show here is the way I always do it on a riding mower. Takes 10 minutes, tops.
@@FixEverythingYourself , actually a riding lawnmower. Doing that on my mother's riding lawnmower would work with say a cement block to tilt it up. On my mower and the double blade, the deck would get bent if I tried that. I agree, removing the deck is a pain when you can do it this way is much better.
Didn't he just do it though?
@@Arock1984 yes he sure did. Raise the deck to highest setting and the deck tilts a little as well. It is very doable. You are correct
@@FixEverythingYourself Same way I do it.
Couldn't you use a car jack to get to the blade?
Sure, just need a little bit of room to get under the deck and access the nuts that hold the blades on.
@@FixEverythingYourself thank you
Those blades that you took off look goo so if you wanna save money but your blades are dull and look like his just sharpen them
Yep. The reason I was replacing blades is because I hit a stump which bent one badly. I replaced both but kept the good one for a spare since it still had plenty of life left.
or you can drive the front tires up a ramp, like a normal human being. lol
Not all normal human beings have ramps. Hence, this option.
LOL@@@ Unless of course the nuts holding the blades on are seized!! Then plan on a 2 hour job.
2 minutes with a milwaukee impact wrench
Don't show changing the blades ha
How the fk
I noticed clockwise anyone else did?
Clockwise is relative to your point of view. Looking from above toward the ground, you would see clockwise. From below (where the bolt is) looking up, you have counterclockwise. Maybe a better description would be the type of bolt (standard or reverse thread).
