Curious if anyone else has had this happen. Other day I was out moving snow, doing a lot of that lately. My oil pressure light flickered on, went out for awhile, then came on steady. I shut the tractor down, started checking for leaks, and then checked other levels like radiator, hydro to see if something had leaked into the oil to thin it out. Everything was as it should be. (Had checked all levels prior to starting up for the day, too.) Found nothing wrong. Started it up the next day and carefully watched it run for half an hour, no pressure light, so back out to move snow I went. After about 10 minutes the pressure warning light came on again and I shut her down. Went through the tech manual and found the list of what to do. Besides oil level (the obvious) it tells how to check the pressure sensor. OK, I could do that except for the wire you need to disconnect to run the ohm test is blocked by a pipe and I didn't want to cut/spice the wire back together. OK, another thing it lists is change the oil filter. Well, I always change fluids/filters way before the JD recommended time frames. In many years of CUT ownership I have never had that be an issue either. But I had a filter on hand so I thought why not. Now, after 15hrs run time and all is well. Just got done changing the oil and filter out again to be safe. Anyone else have this happen? By the way, oil and filters are all genuine JD.
