stuck blade

[mnb]

While mowing I accidentally hit a stump that was barely sticking out of the ground with my 60" lazer. I was changing the blades today and the side I hit the stump with will not come off, I used a impact wrench and got the other two off but I could not get the last one off. Any suggestions or tips? Thanks

You are going to need a breaker bar( long pipe) and stick your ratchet in it and use a peice of wood to hold the blade. That should get the bolt off. I would check the spindle and other stuff under there also, to see if it messed up something else.

yup what ^^^^^^ he said. Use a big breaker bar. Im not sure how yours mount. If its a bolt all the way through. Take a 15/16 wrench for the top and a breaker bar undernesth. If its just a bolt on the bottom. Take a 2x4 to wedge the blade against the desk. That should work.

Yup... and also be alert to the fact that in the process YOU 'may' flex that blade to the point it will not spring back... causing it to be slightly out of whack... if it's not already destroyed.

You are probably gonna have to put some heat on that nut or bolt ( bolt I guess on the lazer). Like a blow torch of some kind. Then you can break it loose. Now I'm not talking red hot, but pour the heat to it for about 30 seconds and that should do it.

There are a couple ways to increase the loosening torque of a air gun. Increase the air pressure to the max avaiable. Sometimes the gun will have speed settings. Use fastest speed. If the bolt goes all the way through, put a wrench on the opposite side and back it against something solid. This gives the hammer in the gun something to hammer against. Also put some penetrating oil on the nut and threads. Don't be afraid to keep that trigger on for a while, sometimes when you are about ready to give up, it breaks.

I've done the same thing with my Lazer. Take it to an automotive shop and ask them if they will take it off for you. Unless you've got a snap-on, matco, or other professional gun you won't get it off. They might even have a 3/4" gun that will take it off very easy. If you try and wedge the blade and use a breaker bar you will probably bend the blade- $15 bucks down the drain. The shop might charge $5 bucks to zip it off. Money and time well spent if you ask me.

That's what I do, for some reason auto repair guys seem to enjoy trying to get mower blades off... I normally give them $5 but sometimes even they refuse the money. A lot faster then messing with it yourself quite often.

Thanks for all the responses, I'll probably take it to the auto shop.
