Only a couple of hours after purchasing my 6410 and running it in the hay field, my left hand reverser switched kicked into neutral and then had a constant "beep" while in gear and running. From then on the tractor would start beeping after 30-45 minuets of running. The tractor was running fine, but I was trying to solve the "beeping" issue because it was about to drive me crazy! I changed the pressure sensor, both hydraulic filters and transmission filter to begin with because that's where someone told me to start at. That didn't solve anything. Several weeks later, tractor still beeping, decided to try and replace the enable pressure switch. After changing it, the tractor will not go forward or backwards, but still beeps when we put it in gear. I'm not getting any fire to the foward or reverse solenoids. The enable solenoid seems to be engaged all the time. I've checked all 4 relays in fuse panel and they check to be good. Even bought a new relay to move t each location to verify. Also checked park break switch and it's still beeping. If ANYBODY has any suggestions, I would greatly appreciate it.

Just wondering if you ever got to the bottom of this fault and queue it because I’ve got the exact same fault on my John, 6210?

Power Reverser switch assembly fixed my 5093E for flashing neutral light & beeping Not taking forward or reverse.

The brass contacts inside switch were worn completely out.

Drove me absolutely crazy until I figure it out.
