Hi all, Im thinking about picking up a 3016 that needs to be repowered but is complete minus engine, Im trying to figure out why some of these tractors are driving the pump from the flywheel side of the engine and others are driving it from the shaft side? Are the pumps Bi-Directional? From the pics of 3016s ive seen it looks like they are driven off the flywheel, and the PTO is on the shaft, I have a Predator 670 in a JD 316 that has a slipping transaxle I would use the engine out of. Also do these Hy Drive tractors pick up speed on downhill grades or do they hold back similar to a manual trans? Any help is appreciated.
