Lawn Mower Blade stuck!

kevingalaxyApril 15, 2009

Hi, i have a craftsman 22 inch mulching mower, the nut just wont come off, ive tried wd-40, wrenches, the manual says turn it counter clockwise? Does this sound right maybe they got it wrong? Should i buy an impact wrench and try and get it off? Ideas?

Take the spark plug wire off the plug and ground it. Turn the mower up on it's side with the carburetor on the high side. Take a piece of wood and block the blade - sometimes you have to hold the wood block by standing on it. Using a long ratchet handle or breaker bar, put your weight on it and break the nut loose. Yes, counter-clockwise is right (also 'lefty-loosey, righty tighty').

I just went through this recently.I let pb blaster(wd40 but better),let it sit for 24 hours or so,really soak it in.

Then I used a breaker bar as saxman said and it broke loose.You need more leverage and just soak the hell out of the nut.

Also, a 6-point socket, or end wrench.
Don't even think of using a crescent wrench.
Also, warm it up the nut a 'little' with your propane
torch, but not too much as you might damage
the lower engine seal.

If you don't have a breaker bar or a long ratchet handle take a regular ratchet hand and put a long pipe over it for leverage - worked for me and of course following all the safety precautions above.

I always use a pipe.
