Are you guys familiar with these? I wasn't aware they were available and saw them at the NE Grows show yesterday. Basically, it is a bolt-on track system for skid steers. Take your tires off, slide on the track assembly and bolt to the wheel hubs. Maybe the best of both worlds? I stopped by the booth a few times throughout the day, and there was always a line of people waiting to talk, so I didn't get to talk to anyone. This must be a fairly new product. I talked to at least 5 different dealers this fall when shopping for a new skid, unsure if I was going wheels or tracks, and no one mentioned this to me. Not even the dealer at the show that had the display. Advantages to this system? Disadvantages? What do you think?
