Removing brush hog blades

[ning]

This thread is simultaneously making me want to pull my blades (while I can) and dread pulling my blades (because I probably can't)
Which will win?
I'll put it on my to-do list

Are they off yet?

For me I use my 1/2-inch Milwaukee high-capacity impact and then I use my air hammer with a flat pounding ponding tool in it.

I just did these on my super well used (not quite used up) King Kutter. Came with my tractor purchase last year. Has the same pinched up "key". Difference for me was that the bolt spun and I couldn't get the nuts off.

I ended up having to drop the stump jumper and just cut the nuts off with an angle grinder and a cutting disc. Made it lots easier to work on out of the machine.

Turns out the slot for the bolt is also just rusted away, so I held the mushroom with channel locks until I could just zap them tight with the impact.

Doubt I'll have to replace these again before something on this thing dies entirely. I figure its a good thing for me to learn how to weld on since I can't make it much worse....

I have an old King Kutter 6'.
Years ago I had trouble removing the bolts. After I had the blades sharpened, I painted the thread, and shoulder of the bolt with Thread-Eze. I've had the bolts out many times since then and the Thread-Eze is still there, so I don't add more.
Now that I have a 4" grinder, I sharpen the blades on the mower. I raise the mower, place 8"sq wood blocks under each side. This gives me plenty of room for access when sharpening.
The blades hinge on the bolts, so I C'clamp a stop on the backside of the blade and lay under the rear of the deck.
It's surprising how fast a 4" grinder will resharpen a blade, unless the leading edge resembles a #2 pencil.

O/A torch with a Rosebud end always does the deed.

Without a doubt the stump jumper is flexing everytime you hit the bolt, take a good bottle jack and jack it up on the stump jumper as close to the bolt hole as you can get it, then hit the bolt with a brass pin or whatever driver that you have and it will come right out. Many years ago I was in the same situation and had beat till I was give out, my dad rode up on his horse and saw what was going on and asked me if I wanted that bolt out, I told him that I wanted both of them out, so he told me get him a bottle jack and in just a minute the bolts were out, he got back on his horse and rode off never said a word about it, I wish he was still here to get advice from.

Lineman he was smart and he had been there. I might add that the effectiveness would be enhanced, if a fellow had the luxury of a concrete pad to be working on. But I miss the past generation too. And we are the old folks now. Thanks for that suggestion it will help me out to

Yes he had, when it came to farming, cows, horses etc he always had the answers I needed, I try to help my now grown boys out without being asked and like him without saying to much about it, time is precious and you are spot on about us being the older folks now.
