Thanks for the tip. I should have mentioned that I had installed a mechanical gage to see what the actual oil pressure was. When cold I have 40 psig and as it warms up it drops to 10 with spikes up to 35. I have owned the tractor since it was new and this problem showed up late last summer, basically over night. I will check the oil filter mount for a relief valve and see it the spring or ball is bad. Otherwise I am probably going to have to check the oil pump out.
