Forget to release brake lock

It seems like this might be mildly genius, but I feel like there has to be a catch. If it was the perfect solution, then all the manufacturers would be doing it.

Putting any tractor in netural should do that.

If I understand you correctly, I don't think locking the driveline in the neutral position would be good. One would never be able to move the gear shifter out of any gear without the tractor being completely stopped. This would defeat the purpose of having synchronized gears in some of the newer gear tractors.

It would also make the tractor kind of a bugger to tow.

I just don't see any reason for a tractor transmission to work any different than a car transmission.

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?

Park in a car does the same as netural does except it also locks the wheels from turning.

That's exactly what I've been trying to say for the past three posts in this thread. I feel like you're either not reading what I'm typing at all, or you're just messing with me.

I said pawl locked driveline and you say putting any tractor in neutral should do that. No no no.

I explained that putting a tractor in neutral should not lock the driveline and you tell me it shouldn't be any different than a car. That's kind of what I just said.

I think my left brake will wear out before the right since I do forget from time to time and move a little before I realize I left it on.

The brakes on our Allis tractors you can't even move if the brake is pulled.

I think we weren't typin each others reading; but now we've got it together.
