Welcome to the forum!
You picked a great Cub. Yes, there is an easy adjustment to the hydro "neutral" that involves loosening a couple bolts on the hydro that holds the control plate and tapping it up or down a TINY amount, like a mm (1/16 inch) to get the tractor to sit still. You need the manual in front of you, looking at the tractor, to figure it out, but it's easy once you see what needs to be done. You MIGHT, first time, take the seat and rear fenders off to do it, it will give you much better view and access. Besides, it will give you a chance to clean things up under there--stuff has a way of piling up under there!
