Having trouble removing one of the blades under the mower deck. Take the deck off the mower and place it on work horses upside down for easy access. The bolt holding the blade will not budge. Have put Liquid Wrench on the bolt and let it soak overnight then tried the largest wrench I have (12" adjustable). Have even extended the wrench for more leverage using a steel pipe but that bolt just laughs at me. Any suggestions?

If you don't have a impact wrench, you might try a socket with a long handle, hit the handle with with a hammer or something heavy. If that does not work, try heating the part the bolt screws into with a propane torch. Don't give up!

Try going the other direction.. you may not be able to *see* any movement but if it breaks the rust a bit, it'll help. Then load it up with penetrating oil again and come back in an hour.. try loosening. Just be careful. Breaking it off will add to your fun..

Just a thought, it may be a reverse thread bolt. Are you sure your going the right direction?

Oh yeah that would be more "fun" than a barrel of monkeys. :smile: My main concern is rounding the bolt head corners. That would also be "fun". :eek:

Assume it's the standard counter-clockwise direction since the other 2 blades are that way.

get rid of the crecent wrench , it will round the head of the bolt, use a good 6 pt socket with a breaker bar
