John deere 4600 hydro engine suddenly stopped

[sqdqo]

Running my JD 4600 hydro tonight and the engine stopped running when I got off the seat. PTO not engaged. I left the engine idling and when I got off the seat to exit the cab the engine stopped. I didn't think much of it but when I got back in the cab and tried to start it the starter would not energize. When I turn the key the cab fan comes on and the dash lites come on but no starter. I tilted the seat forward to locate the saftey switch and held the safety switch button down while turning the key, again the fan comes on as well as the dash lights but no starter. I let up on the switch, turn the key and as expected nothing happens, no fan, no lights. Any help is appreciated.

Sounds like a neutral switch on the hydro pedal is not working properly. Try holding the key in the crank position while you "wiggle" the forward and reverse pedals. Also check for any loose wires on the switch. Neutral switch is #46 in diagram.

On my 4500, the PTO switch is in the dash and I occasionally have to turn it slightly in order to be able to crank (even though the switch action is only in and out). If that is the set up on your 4600, give it a try.

There is a 2 conductor circuit underneath the tractor to the left of the pedals that has a snap together connector, the connector had come apart and would not stay together without electrical tape. I put it back together and it started. It must be part of a safety circuit. I'll have to make a permanent repair when I can get it to a better location.
