2 different tractors. One is a Powershift, one is CVT.
First, grease the shaft as other have said. If it works fine until your hydraulic oil gets hot, it may be a valve problem on the OP's 665B. We see a little of that, but not a ton. The park lock on the CVT has been fairly reliable if greased often.
