1987 #7BC01181, early series with Perkins engine
Wouldn't you know it, 1st day of winter! This morning about 30 minutes after start and some light snow-work the warning horn sounded and the oil light lit up, first intermittently . When sounding the tractor wouldn't move. Ultimately the condition became steady and tractor became immobilized. If I wait and restart half an hour later I get a few seconds of mobility, using this and some downhill I managed to park myself out of my own way.
This is news to me, the oil light and horn never stopped me before. The pressure is 70psi on a good aftermarket electric pr. gauge. I tried to find the pr. SWITCH but cannot locate it on the engine. Anyway I'm not sure if this is an engine problem at all, may be a transmission issue but there's no info in the operator manual or the parts manual. The transmission oil quantity is good. The shop manual has a very short TS note about "low transmision oil pressure" i.e. oil pump failure or suction leak, period.
Right now the tractor is half a mile from house until I manage to tow it in.
Any hunches or experience?
