I have the aggressive, or ribbed tires on my grasshopper front mount. They're similar to what I think Dixie calls the "turf boss". Well, these are the stock tires, and now I'm wishing I got the turf tires instead. I'm having a hell of time zero-turning and not tearing up grass. Doing fine with the walkbehind, and did fine with a demo JD stander, so it's gotta be the tires, right? Can this problem be overcome, or do I need to switch tires? Losing a lot of time by not being able to zero turn. Attached is pic from grasshopper website to show the tires. Not sure how it will show up but, here goes nothin.
