Hit rock and bent mower deck

I've used a 10lb sledge to correct some of those types of annoyances. BFH works!

I actually imbedded the blade into the top of the deck on a cheap MTD mower after hitting a rock. It cut about a 2" slot into the deck and the blade looked more like a banana than a blade. Of course the sheet metal on that deck isn't anywhere near as thick as a Kubota deck. A new set of blades and some hammering and welding and it's as good as new, well not new but no worse looking than before it happened. The lesson learned, granite doesn't like to be mowed.

Sounds good. As an aside, is that what you would use to remove the fixture that secures the blade to the deck? This would be a good opportunity to remove the blades for sharpening or replacement. And would you typically need a breaker bar for that job. And is there a torque measure requirement, or just tighten "to taste."
Thanks for the help.

Pipe wrench to fix the deck. quick and easy. Always use an impact to remove the blades. Either pnuematic or electric/battery powered one. Quick and easy and better for this than any other tool.

On my BX24 60" deck the blade bolts are 30mm and supposed to be torqued to 72-87 ft/lbs. I wedged the blade with a piece of wood and used a breaker bar. I also use anti-seize on the threads.

A big crescent wrench works for me on that lip. I straighten it once a year when I put it into storage.

I don't understand why so many folks are bending the lip of their mower decks. Are they not reinforced any more? The deck on my ZD21 has a 1/2" × 1" bar welded around the entire perimeter. The JD 7-Iron deck has what appears to be a 3/4" round bar welded to it's perimeter. I haven't bent a deck lip yet, though i have bumped a few stumps, rocks, and fence posts. Both of these decks are made from 1/8" or thicker material. I sure wouldn't want to try to bend either of these decks with a pipe wrench and cheater bar. I guess they just don't make them like they used to.....lol.
