Steel tracks will do less damage than the rubber on pavement, just a few scratches are left behind, and they fade over time. turning on grass is better though, steel slides better than rubber, assuming the pads are triple grousers and NOT singles. They will limit the speed, as the weight and vibrations will tear them apart despite Bobcat's pipe dream that they think their products are indestructible.
I guess that depends on what you consider pavement. Concrete? Yeah, some scratches, but how are some scratches 'less damage' than none at all? Steel will tear asphalt to shreads and if it's summer and hot, one pass over an asphalt parking lot and you'll be in deep doo-doo.
I'm assuming that Bobcat will of course be thinking of some kind of modification of undercarriage parts to carry steel tracks.
With the correct rollers, drive sprocket and shoe design, vibration could be similar to rubber. Chain-and-shoe tracks are not for high speed on any machine.
One great benefit I see over rubber is that the links bend easier, going around the end rollers--you're not constantly trying to fold three phone-books in half for every inch of travel. I'm not sure steel would weigh that much more than the rubber tracks-so I think there would be a great net HP available improvement.
Ron-you murdered your T190 through neglect and abuse, and you let it sour you on Bobcat-your denial of your responsibility and desire to blame your actions or lack of care on manufacturing flaws is typical of the common and growing problem of free individuals in Western society who refuse to take responsibility for their own actions, hence the incessant Bobcat-bashing.
I think some introspection is in order on your part, consider this unqualified but "free" therapy.......=).
