John Deere 185 Hydro stops when PTO is engaged
Posted January 02, 2015 - 07:00 PM
The problem is when I engage the electric PTO, it kills the engine. I know this model has several safety interlocks(seat, brake, PTO and shifter position?) that all work together. The PTO does engage for a second before it kills the engine.
More news. Why was the mower idle for so long? The bolts for the axle pivot came out and the steer axle rolled. I stood the mower on end, lowered the mowing deck, pulled the PTO, straightened the crossmember and reinstalled the axle.
After that, I got it fired up, warmed up and changed the oil, then it was finished.
Could I have messed something up when I pulled the PTO?
Do I have a bad connection somewhere?
The PTO switch seems overly complicated--it must have 8 or 10 wires coming out of it.
What do I need to check next?
In case it matters, it's an 86 model, Kawasaki engine and it hasn't been monkeyed with except what I did today.

Sounds like a safety switch problem, or the wiring connected to the safety switch(s).
Do you have a multi-meter and know how to use it?

Does the seat safety switch on the JD 185 only have an affect with the PTO or will it shut off the engine even with the PTO disengaged? How did you bypass the seat safety switch? <-- this is where I think the issue might be.

To bypass the seat switch, I disconnected it and jumpered the two wires together.
It's my understanding the seat switch and PTO switch are independent of each other, but I'm not willing to bet money on it.
I couldn't get the starter to engage until I bypassed the seat switch.
