Yes sir. Most European tractors only started getting watercooled maybe in late 80's, early 90's, when emissions started to be a bit more strict. At least up to 75 HP, maybe more.
Those engines were awesome. Stupidly overbuilt, huge displacement for the HP, reliable, easy to work on, lasted forever with basic maintenance, plus another great thing is these engines would run at very low RPM while producing crazy amounts of torque.
Some older Deutz tractors would run easily 15 to 20 thousand hours with just the basic maintenance.
