I was just wondering if anyone has any experience with either the steel or rubber tracks made for the Dingo 220, 222 or 322. Do you use them. If so, how does it affect the performance and rutting of the machine. How about making the machine tip easier going over obstacles? I have a 220 and Toro doesnt recommend the rubber tracks for it. Do any of you know why the steel are fine but not the rubber?? I suspect it is just a marketing plow to get people to buy the more expensive 222. Any feedback would be appreciated.
