Ariens Ikon X 52 w/22hp Kohler Courage - Rpms?

[Turbodriven]

I believe it's a 2018 if it matters. From zero throttle to half throttle the engine is at idle at about 1600 RPMs. From half throttle to Full Throttle the RPMs increase to about 2600 Rpms (sitting still, pto not engaged). What should I be expecting on this mower? I feel like the throttle lever / cable is not adjusted properly, and that's easy to fix I think but I'm wondering what the rpm range I'm shooting for is?

I set these units at 3200 RPMs.
