Can’t get the bolt out, it stuck in the blade!

[MowerDad85]

My dad always makes my poor mower do harsh jobs. Like last week, he was mowing using my John Deere Ztrak mower (48” deck),
He hit the edge of a net and it yanked the bolt so hard that the mower blade came flying off. No, no… no one’s got hurt, don’t worry.
The silly thing is tht when I put the blade back on, somehow I forgot to put the washer back on

Anyway, I went to change the blades yesterday, and the blade on the left side of the mower deck is stuck solid. It looks like the bolt has somehow wiggled its way up into the blade itself.

We've tried using an impact wrench to get it off, but it’s hard to get a good grip on it. Does anyone here know what I should do?

Try applying some penetrating oil to loosen it up, then tap the bolt lightly with a hammer. If that doesn't work, try cutting the bolt or remove the deck to get better access.

+1 on this but you can also use a torch to the bolt area and it doesn't need to be flaming hot, you just need enough heat to break the bond. Then let it cool then try tapping with the wrench again.

Oh no, it's kinda tough when other people don't understand the boundaries of what we own. Glad no one got hurt... Don't forget the washer next time. Cut off the bolt head as a last resort and use a grinder for that.

try a breaker bar and add some heat. Can't be stuck if its liquid, right?

Haha, I love your reasoning! Using heat along with a breaker bar is a classic combination. Just make sure you don't melt the mower
