Do they make mud tire version? do those flex out and gain more traction?
This is the first machine I've ever had with Twheels, so I don't know what other tread styles are available. But they do put more surface area on the ground. Probably 30% (or more) ground contact than regular turf tires. It holds a hillside far better than the turf tires. This one is just a demo, but I'm pretty sure there's a new one in my future, real soon.
