Removing brush hog blades

Put a few blocks under the stump jumper and beat the bolt with a large hammer and punch. I think I used a length of rebar on the bolt and hit it with a 4 pound sledge hammer.

Try an impact wrench on bolt #33.

If heating and/or rust solvent fails, cut the bolt flush with the blade; then drill out the center of the bolt.

That’s weird cause mine usually just fall out.
I'm guessing that you replace yours more than once every 20 years. The unit looked in decent shape from above but I was in a hurry and didn't check the blades. They're worn to the point that they're just rounded off steel bars with no hint there was ever an edge. I doubt they have ever been replaced.

It doesn't show on the diagram but bolt #33 doesn't have any flats. It's a thin round head. Also it's got a key that keeps it from turning.

Suspect the " key" on the bolt shank has spun in the stump jumper hole and locked up. If you support the stump jumper underneath so it cannot flex you may be able to drive bolts out with a piece of 1" steel rod. Had 1 on my Bushhog Squealer once do that and finally was able to drive the bolt out. Key had rotated a bit and wedged in bolt hole. 3 pound hand sledge and hardened steel rod finally beat it out.

So the big shoulder is in the blade. The spline part of the bolt looks like it presses in the stump jumper. Now how do you get a pressed in bolt out after years of rusting and all kinds of Temputure changes. I think it needs burning out with a cutting torch. If it’s possible to get to it. Only an opinion guys. Good luck
