PTO position lever locks.

[Sawman10]

What are the locks on the PTO position lever called and where can i find some ?

I am talking about the lock that allows the PTO lever to be set in the same position each time.

I have searched but cant find them or the name.

Are you perchance referring to the three point up and down stops? My PTO lever is either to engage or disengage the PTO. I have no other positions.
