Yes.Have a dealer handle it. Maybe some basic purge or set up, but you don't want to let a hydro issue become your problem out of warranty.

I'm having the exact same problem. At first Toro told my dealer it was a linkage problem and that there were 4 or 5 reported in the whole United States. My dealer took it in and said that everything was o.k. and they lubed the linkage. Later I told him it was doing the same thing and he said Toro told him that that's how they are and it's o.k. I took him a video today of how the right side won't move backing up a hill and it would go in circles. They are going yo pick it up today to check it again. I don't find this acceptable at all.

eric......i was wondering what your final outcome from the dealer was...on the repair
