I have a friend with an ASV rubber track skid loader. It seems pretty slick, but is it worth the extra money for a machine with rubber tracks. I do primarily yard grading (1-2 acres) with a harley rake. The machine I have (JCB 165) seems to work fine, but considering the tracks. My unit is the high flow machine, and the pump is in the way if I wanted to add tracks to my machine. Just wondering if anyone uses the ASV, or another rubber track skid steer.
