Last season I ran a bobcat T-190 with isolated controls. Great Machine pushes good, great for stacking snow and cutting ice or hard pack snow, is a little slick on the ice or on hilled drives, and yes it is ruff riding when the pavement is bare. Also run Bobcat S-220 Isolated controls. Also a great machine will do everything that the track machine does except going up a pile to stack snow you will get stuck but it will out do the tracks on the hills. This year I have a Cat 226B (Tires) I liked it a lot, Cat cabs are more comfortable, controls are better. This is a smaller machine will do anything the bobcats will do but still it is a tire machine and hard to stack with, also it is light and does not like to cut the hard pack. But it is much nicer to tow around in the slick stuff. I also have a Cat 257B, Awesome Machine, Same cab and controls as the 226 just bigger machine. Seems to move anything. Does better on the slick stuff then the T-190 but still not as good as a Tire machine, you need to be on your toes if you have a hilled area and plan it out to work from the top down because you may not get up the hill again if you clear the bottom first. This is a heavy machine, around 8000 pounds, you need to have a good tow vehicle and trailer if you are thinking of a machine in this size range. All of these are rentals, I have been renting for a few years trying to run all different makes, models, and size so when I go to buy I get what is best for me. If these track machines where mine I would be trying anything I could to give them a little more traction on the ice and hills. My ranking order of the four machines is
CAT 257B
BOBCAT T-190
BOBCAT S-220
CAT 226B Very close behind the S-220 only behind do to ability to cut hard pack
Also all of these machines have enclosed heated cabs. If I was buying at this time I would be looking for a CAT 247B this is the same as the 257 but about 1000 pounds lighter.
