Well Big Josh welcome to the site!
Factors: Width of tire, weight of machine, inertia, soil type, pitch of lawn, soil moisture, density/type of turf.
There are more but thats good to start.
Z mowers can be a fantastic tool in the right hands.
What determines that is the users ability to manage turning, terrain, and mowing conditions.
I think That the average new user finds that (he) can go fast in a straight line, but ripps up the turf on the corners.
Tire width plays a big factor here. A wide tire when turned 180 will rip grass out.
The trick is when you either have to do a K turn or the "rolling turn". Make sure you slow down as you approach your turning area, wet soils can really slip and you can peel large amounts of sod without realizing it (at first)
Practice if you can, on non critical areas and what I do is run the machine with 1 hand on both sticks rocking the wrist to steer. (a habit from running a Walker) try that too.
