View Full Version : Scag Hydro Issues

I had some issues start with my 2008 61'' Scag 25hp Kohler ZTR last summer. The previous owner had the last right hydro replaced under warranty. The mower one day ran well, next day the left hydro was not going as fast as the right. I pulled out the book and adjusted the hydro, which didn't help. I have taken it to two different shops, now the nuetral part of the hydro is so out of whack it rolls backwards when you engage the hydros. The last place charged me $40 and said they slowed down the right hydro. I've used it this way for about 200 hours now so I don't think the hydro is actually bad. What is everyone missing?

Is this a TT, wildcat, or cub?

A good shop can test the pumps to see the flow drop with the right equipment. It would tell you if they are in spec or not.
