If you buy a track loader without a suspension system on it you are NUTS. Personally I wouldn't have a Bobcat track loader if you gave it to me!! The only one i'd have is an ASV, or it's newer brother, Terex. Go to Youtube and look for" Bobcat T190 versus ASV and watch the video!! NO comparison!!! Plus with the ASV you won't have all that (cough!!) "safety" crap that a Bobcat has on it. New Holland and Gehl wheel loaders rule the roost when it comes to wheel loaders, but they don't even make their own their track machines - Takeuchi makes them!!!!! You're gonna be REALLY ticked off if you buy a Bobcat track loader, then go drive and ASV!!! By the way....... that ASV has a Perkins diesel in it. Perkins was bought out by cat several years ago! And I know for a fact that Cat tracks will fit on it, and so will the joysticks!!!! Anything but a Bobcat is SO much easier to work on than a Bobcat!!!!!
