My old IH had a hydraulic dump valve that you could push with your heel. That would remove all hydrualic pressure from the system when starting the engine. How hard would it be to modify a PT for that?
Right now, as I understand it, when the treadle peddle is in neutral, the variable volume pump isn't pushing much oil, just the charge pump section. So the only real load would be the PTO pumps, which power the PTO, the steering and the lift circuits. The PTO pump has no load with no implement attached or running, so the main drag would probably be the steering/lift/aux PTO pump section. Any thoughts on bypassing that?
