Consider who has the closest parts and service to your locations. Around here Bobcat is the biggest network, but it probably just gets down to the Ford, Chevy, GMC debate as to which brand is best. I have had several wheeled bobcats, and now also have a tracked one. We just demolished a swimming pool and the wheeled machine could not make it down and out of the deep end of the pool, too steep and slippery. The T190 could go up and down, and cope with the mudhole at the bottom of the hole after the pool shell was gone. If I had to have only one, I would have a tracked machine. But if you are running on asphalt a lot, a new set of tracks is much more expensive than a set of tires.
What is the difference between the two models?
