Ford 1100 Hydraulic Tank Replacement/Repair

[Douglas Bee]

I have a tractor that mysteriously jack-knifed the rotary cutter into the hydraulic fluid tank and punched a half dollar sized hole in it. I am assuming that this is why the implements will no longer lift but at the end of the day this may end up being only part of the issue. In any event, my daughter's husband, the culprit, JB welded the piece back into place. That not having worked, I took the tractor in to be welded and the welder could not do it. My son-in-law is a nurse practitioner who does not have experience using JB Weld, hopefully, in his line of work. Anyway, I cannot find anyone to work on this tractor nor can I find a replacement (tank, not son-in-law). Short of getting rid of the son-in-law, does anyone know what I can do to rectify this issue? Son-in-law replacement is not entirely out of the question.
