Loosening seized bolts

Have you tried knocking them with hammer to shock them a bit, it will only be rust on the threads stopping them from moving. And when I say hit with hammer I mean whack them with heaviest lump hammer you have. Have you had a 3/4” bar and pipe on them? Stick it back on tractor upside down to make it easier to work on.
Otherwise you need to warm the top clevis to get the bolts to move. If and when you get them to move, move them back and forty to loosen up. Please dont weld them, it’s a pet hate of mine seeing them welded as it just looks wrong and as you never know when you will need to remove one clevis if the machine has a pair o fixed clevises.

If memory serves ,they are a fine thread or they were on the 500 range ,,
I think the heat is the only answer, I'll have to find someone with heating gear. There's a good chance these bolts are in place with over 40 years.

Heat.
Will the bolts turn
One job were the oxy propane, acetylene wins hands down.
Heat one flat of a nut to expand it , ur trying to expand one bit a tho, so concentrate the heat on one bit ,

You need someone with bottlesAs in attached photo.
The 2 pieces are the tiniest fraction loose, yet the bolts are seized solid, won't loosen or tighten.
It's for a 100 series MF
Would it be OK to get a welder to join the 2 pieces together?
To heat them .

And how is he removing the rest of the seized bolts after the heads are cut off? The bolts don't go right through. The clevis is threaded...
How will a grinder help? I can cut the heads off the bolts or slice in between the two parts. Neither will loosen the seized threads inside.
Petition: Temporary Ban on agricultural use of sewage cake
In order to protect our land, we’re seeking a temporary ban of the agricultural use of sewage cake until better testing and treatment of waste can be proven. We call on all farmers after this harvest to refuse to accept any more until things change.
Some research suggests that the contamination of land is far more serious than just heavy metal build ups. There is an increasing amount of micro plastics and forever chemicals appearing in sewage cake. We think testing for these when it leaves the processing plants isn’t adequate, and that processing needs to adapt to be able to remove these contaminants.
