Oil cooler is on the return side of power steering valve, and is supply line to input shafts retainer in trans front. Pressure is 150-200 at PTO control valve, is regulated by a valve built into retainer cover. That is the pressure the cooler has do deal with. If tractor is used hard in hot weather cooler is a good idea. If not, it would not be needed. I had an 85 gas that cooler was removed from, no trouble as it never ran more than 2 hours each time it was used. Super 90 had a cooler too, but was designed much different than 85 was.

Yes, this is return oil to PTO closed center shift valve. Pressure is regulated by a valve in transmission front plate.

So, sounds like if I want to brush hog with it in the summer, I had better come up with a cooler? The lines don't look like they have been changed or altered. I wonder if a transmission cooler off of a Ford pickup with the rubber hoses could handle the pressure? Or should I flare the ends on the cooler and make up some short hydraulic hoses?

Spring you have missing is for draft control follow up linkage, senses draft control frame movement.
