Hi topgun.Hang in there. From the sounds of it you are doing something right. You have worked your tractor a bit since changing the oil and bringing it back to the proper level.My son has an expression.When asked if it is the oil pump or the water pump or whatever pump that is the problem he says Not necessarily!.Your oil pressure light is on, does that mean my oil pump is gone. Not necessarily!!!!!!!. Like I say hang in there. These guys will help you get it figured out. Have a great holiday and then keep us posted. Dusty
