Loosening seized bolts

As 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?

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.

Id go with heat rather than an impact gun or 3/4 with bar. If u broke the head off ur gonna be in for more head scratchin
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 ,
 

Rejuvenating swards: Which option is best?

Written by Brian McDonnell

Maintaining grass quality during mid-season grazing is important. Farmers can maintain quality by entering ideal grazing covers of 1,300 – 1,500kg DM/ha, and grazing down to a residual of 4cm every rotation.

If you are now in a situation where cows are not cleaning out paddocks as well as they should be, leading to the development of steamy grass within the sward, here are some options.

Common options for rejuvenating swards include:

  1. Take a silage cut, probably into bales, remove the material and start again with the aftermath...
