Ferris ProCut S

[Dog Gone It]

Wanting to know if anyone has any experience with these.
Im concerned about the wheels spinning while at an angle on a slope.
They mention wheel spinning in the attached video starting at around the 2:00 minute mark, but I dont know if its a common problem, or if they are referring to something else related to loading/unloading.

Over the last couple of years Ive read several different times that front mount mowers can mow a hill/slope better than a midmount.
So Im wondering if this ProCut S is any better or worse than other front mounts due to its design.
