....zero turns have no brakes or steering with the engine not running,

Say what? Is this universal, or just for one particular brand or manufacturer?

We've been looking at them on & off for a year or so, to replace our J.D. lawn/garden tractor, but this would be a deal breaker for us.

(Edit: Now that I think about it, since the steering is hydraulic, I guess this makes sense. But the brakes?)
