It sounds like we're not talking about the same thing. Let me try to explain better.

For the most part, the JD 5003 series transmissions are exactly like a car or newer tractor's. The gears are synchronized, and in neutral the motor is completely disconnected from the drive axles. This is just like any other tractor.

What I am talking about is an extra position on the manual gear selector lever labeled park. This park position works just like the park position on an automatic transmission where the drive axles are postively locked against any forward or reverse movement.

This transmission arrangement eliminates the need for a proper parking brake. In fact the 5003 series tractors have no parking brake, thus eliminating the opportunity to drive off with the parking brake on.

Here is a picture. Check out the little dog-leg position on the upper right labeled P.

I'm sorry if I wasn't being sufficiently clear before. Does this make more sense?
