The PTO is always on. Got it started a couple times due to immediate need for the tractor. Kept PTO switch in off position and once the PTO actually did eventually disengage (slowly) and then started operating normally with the PTO on/off switch. Shut the machine down and the condition returned. So after troubleshooting a little and some ohm checks...terminals on top of PTO (naturally with the wires unplugged) is a dead short 0 ohms. Is it normal for the PTO to have 0 ohms across it's terminals when unplugged? Also tried starting tractor while the PTO was disconnected, PTO was still engaged and spun with engine however...engine never started (I assume because of the load with the pto being on)? So...fortunately for me and my bad luck...my PTO is the more expensive one so I figured before I dropped the $$$ I'd ask you forum members for confirmation of my beliefs that the PTO is bad. Any help?
