If all for remotes check 300 lbs, the thermals are NOT the problem, they can only affect the RH two remotes, they are not in the LH side caps. If the thermals are bad the remote cylinder plugged into a failed thermal remote will raise normally and go back down after the lever is returned to neutral. If the pump is good the main relief has probably blown an oring at the top of the sleeve. I have worked on these tractors since they came out at an authorized Case dealership and know the flows involved as I stated before, if the remotes are showing 300 lbs that IS system pressure, unless it has been cobbed up somehow the hitch IS working at the same pressure as the remotes. Don't go down a bunch of bunny trails!!!!!!! I told you this in a previous post , this is what is frustrating about giving info out, you do not know me from Adam and have no clue about my or no others qualifications on here, I get that but I do know those tractors!!
