Kubota M6800 overheating hydraulics

Kubota M6800 2004 4x4 hydraulic oil gets boiling hot after 45 minutes to an hour bush hogging. Tractor doesn't make any unusual noises and I have changed the hydraulic oil and filters, no leakage. Any suggestions on the problem????
 

I'll guess relief valve or other valve must be leaking to cause the heat unless it has a plugged oil cooler. It would be nice if Kubota would put their parts schematics on the internet similar to other farm equipment manufacturers.

To generate that much heat that quick the hydraulic system has be going over relief for some reason. I would have a knowledgable dealer check it out. Maybe the hitch is not cancelling or something of that nature, that is just a guess but something is causeing a restriction to oil flow that is creating that much heat. mEl

I've used Messicks many times in the past. You put in the model and component one is interested in viewing and they will email a parts schematic. Not even close to looking up parts on JD or NH's website. I just viewed Kubota parts and all they show are fast moving parts. No engine,trans or hyd parts schematics. Please feel free to correct me if I'm wrong or point out where I'm missing out on viewing the Internet publicized schematics of Kubota.Thanks,Jim
