John Deere Zero Turn Tracking to the Left

I just purchased a used 2007 717A zero turn with less than 90 hours on it. The mower tracks to the left when pushing both handles forward 100%. I feel as though the right side has more muscle than the left. Since this mower is new to me I'm hoping there are adjustments that can be made.

I didn't find much on the deere website or the owners manual on this. Does anyone know what this could be? Both tires are inflated at the same PSI and it veers enough to know something needs adjusting.

Any help would be greatly appreciated. Thank you,

I have a 717A myself that I have owned since new, and mine does the same thing anymore. I just don't worry about it, because if I'm not going flat out I can just compensate with the levers, and my yard is rough enough that I can't mow at flat out top speed anyway. I know this doesn't help fix your problem but just thought I would let you know that it must be kind of a common issue.

Well hop to it. And when you get there, stand over the mechanic and watch his every move so you can tell this guy what to do to fix his so we don't have to come up with all these lines we are feeding him.:dunno:

I called my local deere dealer and the service guy told me to adjust some nuts/bolts on the lever arm that attach to the hydro line.... He said only do quarter turns as slight adjustments do a lot. I have yet to look at my mower to see what he's talking about.

I have a feeling when I actually view the area I'll be scratching my head saying "what bolt? there's like 5 to choose from!!!".
