I am currently running bobcat s185. I am looking to purchase a track loader and I can get a cat257b or asv 70 for about the same money. I do a lot of heavy hauling on hilly terrain and the wheeled machine is just not the best option. The spec sheets seem to match the cat277 closer to the ASV Sr 70. However my sales rep says the the 257 will far surpass the asv 70 in all aspects. Just thought I would look to some other owners for opions. Thanks for your time.
