BushHog Squealer blade change

[lawnspecialties]

I have a 5' BushHog Squealer with some really dull blades. I found some reasonably priced ones at Tractor Supply but now I can't get the old ones off. Is there something I'm missing? I bought a 1-11/16" socket with a 3/4" drive rachet and thought I'd be all set. Think again. For the life of me I can't get the stinking bolts off. I've already given them a nice Liquid Wrench bath. Do I just need to turn it harder somehow? It's only two years old. Any ideas? Thanks:confused:

either put a pipe on it for leverage, or get the torch out and heat it up, they can be tough.

A little heat should help or a long pipe. I hope you also bought tne bolts when you bought the blades. The Blades turn on the bolts and the bolts will wear at that point. If you bought new bolts I would just torch the old bolts out.
