2640 Slips out of Park

[Sopater]

I have a 2640 that occasionally slips out of park. Not sure why.
A neighbor has one of these on his 2640 that he says holds it in park, but I don't know what it is... any ideas?

PARK LOCK ASSURANCE KIT

Looks like a home made rigging that physically holds it in park. Jury rigged.

No. That was JD answer to it coming out of park. Our 2440 did not have that. When it was recalled to have it installed my grandfather signed off a waiver not to have it. I hear those have issues. When we parked our on the hill to unload sap you made sure it was in park. It never came out. But I could see bumping the lever getting off could have tragic results. There was a slight detent it sat in when in park.

It looks like JD created a Park Lock Assurance Kit. See the PDF file in my second post. I found that after my original post. I was hoping that there was something I could adjust or replaced, but I might need to see about getting that kit. Otherwise, I just need to not park it on a hill and rely on the PARK setting of the shifter.

After rereading your post here are my thoughts. Don’t update it. Leave as it is. When you put it in park. Don’t just push the lever straight up and leave it. Make sure to move it straight up and to the right. With the lever there pull it straight back. It should not go to neutral. If I recall from my childhood. Those updates had an issue with releasing the range lever.

That was the most important instruction we were given as kids when parking the sap tank on the hill. Make sure you can’t pull the lever toward you before getting off the tractor.

That contraption in OP's original post was designed to make placing JD utility tractors "easier to get into park position". I remember supervising installing those kits when I served as the local JD dealer service manager. Trans coming out of park I would suggest to check shift rail tab under shifter cover for excessive wear. Shifter wear wouldn't allow gears to be fully engaged when trans is placed in park position.
