66 Series Tractors Hydraulic System. A friend asked me to help figure out why he has no hydraulics. I have looked everywhere for a serial number, name plate etc and cannot find one. I am sure it is IH and reasonably sure it is a 66 series by looking at the grill, hood etc. Anyway to the problem: Tractor has loader and was working fine last time used and was driven to a spot and parked. Now no hyd. at all on it. The wiring has been rigged,i.e. safety items, ignition switch etc. wired around. I wonder how the hyd.'s know to come on when the tractor starts. Is there an electrically operated valve that allows the hyd. to come on once the tractor is running or does the hyd work similiar to old H and M which come on because of engagement with clutch and drive train. I know this series would be live hyd. but is the system hard coupled and available when the engine starts or could there be a valve that has to shift to allow fluid to the manual hydraulic lever controls to work. Full of clean oil, no obvious fluid on ground.

I’m par
