Started tractor up one morning, about 10-15 degrees, no oil pressure, ran for about 15 seconds tops. Removed line from gauge and cranked over, no oil coming out line. Removed crankcase cover, cranked over by hand, oil pump shaft is spinning and coupler isn't broke.
Put propane heater in front of main case and heated for about 30 minutes. Drain oil. Replaced filter and installed new 5w-30 oil. Cranked over, oil came out oil pressure line. Thought that it was iced up, (was some ice in drain plug).
A few days later, 0-10 degrees, no oil pressure.
What the @$&%. Added some sea-foam to oil and let sit. This last weekend is was warm, 30 degrees.
Tractor started and has oil pressure, let tractor runs for about 1-2 hours and using it some.
Just got 7 inches of snow and whated to try out the snow bucket that I just put on, Guess what, no oil pressure, is about 5 degrees now. My dad used it the day before, about 30 degrees and he said that it had oil pressure. This P.O.S. is really getting me mad. The only things I can think of are the woodruf key on the oil pump drive shaft or gear is worn, and the cold thick oil is allowing shaft to spin and gears are not. Or still has ice some where, but I though that running tractor, would melt any oil, and would settle to bottom of case. I installed a 3 inch pipe in drain hole to catch water. Has anybody else had this happen or any ideas. Thanks Jack.

Maybe your oil pressure gauge does not function when cold.

Jack, it still sounds like water in the oil or the oil pump pick-up screen is almost plugged. The water tends to settle to the bottom around the pump.
~Drain the oil & put it in a bucket, then heat to about 130�-150� then pour it back in & see if you have oil pressure. ~After running the tractor with oil pressure, drain the oil into a container & let it sit out in the cold [in a covered area so dirt doesn't get to it] for a few hours or overnight, then pour the oil off & back into the tractor & see if there is ice in the bottom of the container. It wouldn't hurt to remove the filter & see if there is ice in it. If the filter is iced up it won't pass oil.
~If no water shows up, suspect a plugged pump inlet screen or pump problem.

You may have a problem with your oil pump coupler spinning on the shaft with cold thick oil and not turning the pump.
