Have you noticed it happening after the hydrostatic is up to temperature more so than when it’s cold at startup? Be worth your time to inspect the belt for glazing and proper diameter as well as the v in the pulleys incase it’s slipping under load. But in the end I have a bad feeling someone dumped it on you guys because their assholes who sell mowers with worn out hydros. This kind of thing happens a lot because when the hydros go they are too expensive to have fixed at a shop vs buying new. Gods speed my friend. Answer from Deleted User on reddit.com

Here's the thing, this and most zero turns don't have one transmission, they have two, one for each wheel, which are entirely independent of each other, only linked by a belt and a couple of brackets. When you get a transmission issue, it will almost never effect both transmissions at the same time. So, you'll have issues where the unit always wants to turn one way, you have to give more input both forward and reverse to maintain a straight line, etc. It sounds to me more like you may have a slipping drive belt, a drive/brake linkage issue, or something along those lines. Something that's common to both transmissions.
