Buy an oil pressure gauge (0 - 150)  and hose that you can screw into the engine block and physically see what pressure you're at in psi. Let me know than what it's at.
Haymaker - thanks for your reply;  as it turns out, changing the oil fixed the problem.  the old oil had lost most of its viscosity, probably due to getting diesel fuel in it (it had been a long time since I had changed the oil and I suspect that unburned fuel was getting pushed past the rings).  So this was a learning experience for me.  After the oil change, the oil pressure was normal again and the tractor runs good

Low engine oil pressure with warm engine - 91' 825
« Reply #1 on: May 15, 2017, 03:25:01 PM »
I have a '91 Belarus 825 with about 900 hours that I have owned for about 10 years.  Over about the last year, the engine oil pressure gets lower as the engine warms up.  During the winter, the gage will stay out of the "orange" zone with a warm engine if I keep the engine RPM up.  Now, this spring, even at full engine speed the oil gage is in the "orange" zone after the engine warms up.  Note, at start-up, oil pressure is OK.  Engine is not using oil nor antifreeze.  Engine seems to run OK.  No white smoke.  Any ideas what is happening?
