The key to not tearing turf is to keep the tires rolling instead of locking one or spinning one backwards. I actually can turn around soother with one hand than I can two believe it or not.
Yes, the tire needs to be rolling either frontwards or backwards. But doing a very tight turn can cause the inside tire to scuff and tear turf.
It's easier to learn how to operate a Zero-Turn if you first operate a hydro walk-behind mower, because you can easily see both wheels and what they're doing. I see a lot of homeowners that mow "tractor style" with their Zero-Turn mowers. Kind of defeats the purpose.
Where I am it's expected that professionals mow with straight stripes back and forth, or in some cases along a contour. I do zero turns all day long without damaging lawns. Not like it can't be done. And if it can, then why not?
Note that I run compact and fairly light 52 inch mowers, not full-sized 60 inchers like most around me do.
Edit:. Oh, you run Scags. No wonder. Great machines but heavy. Probably would do a lot of damage if you did what I do. My Bob-Cat is only 850 pounds without the bagger. 52 inch Tiger Cat is 1,100 pounds.
