JD 3320 e-hydro. will not move forward or reverse. Rear Tranny oil was low ,so I topped it off and still no go?from what I have read I might have an airlock in the system now?So how do I bleed the system to remove air?any thoughts?hope to hear from you soon.

Not trying to be a smart alec, but is the tractor in gear? Happened to me for a while :ashamed: till I caught it.

yes tried all gears,no go,what iam reading now, there is an airlock in the system now oil being so low I have to bleed system now!! so wondering how I do that now?then had a error 15 come up,disconnected battery to reboot the ecm.any thoughts?

Code 15 is operator out of seat. In one of your other posts you said engaging PTO would shut down tractor, again electrical problem not hydro problem. You need to start chasing wires for the harness that connects to the seat switch.

yes,bypassed that with pin in seat plug to see what would happen?,still no go?so theres no air lock ur sayin if error 15 keeps coming up?so its an electrical problem?not mechanical? with air and fluids in the e-hydro system? so now backtrack the wire from the seat and see! yes pto switch shutsdown engine right away! whats goin on?

I'd keep chasing that harness back. Look for obvious, rubbed through / rat chewed / plug undone etc. first.
JD Parts will be helpful in at least giving you a diagram to start with. 35 on this diagram is the seat switch.

ok Dusty,thanks for your time and diagram on trying to figure this out asap.Just thought after being low on oil in rearend was the mainthing not error code 15?I have 10foot snow banks out here on Lake Superior,Canada I have to move asap before it floods here.keep you posted .Thanx so much

Agree with Mr.Dusty, Need to chase those wires..

 

[dusty3030]

Make sure none of the pins are pushed out on the plugs / corrosion too. The Ehydro is electronic so it very possibly could be a corroded plug dropping voltage enough to cause the error. Wire pinched but not severed etc. Good luck!
