Where I work we have a Bobcat T190 and a new T300. We also have the old yard horse JD 8875 and had a JD 250. There is no denying that the tracked bobcats can grade more effectively than a rubber tired skid steer. We have also continued work and completed jobs using the T300 where if we had a tire machine we would have been shut down due to the weather. As stated before tracks are expensive to replace but the new tracks on the Bobcats seem to be made better than the ones that originally came on the T190. The track machines are rarely used on pavement, only for snow removal jobs in the winter if it ever gets here. The good thing about the T300 is that it will unload and move a full skid of versa-lok blocks (48 blocks) off a trailer or out of a dump with ease. The lifting capacity is awesome. You have to unstack about a course and a half of block before moving it safely with the T190. These are the benefits of a bigger machine but it also has its drawbacks. The T190 is great b/c it is so manueverable in tight quarters, much smaller than the T300. I do think that the Bobcats are the easiest to perform maintenance on but the visibility out of the back isn't as good as the JD. I have never operated a CAT, Case, Geihl, etc. I am not biased just only had experience in the Bobcats, JD, and NH brands. You can usually find a dealer and tell them that you are seriously interested in buying one and they may let you demo one instead of renting one. Good Luck. Mike
