Have any of you guys used a tree spade on a skid steer? Are they actually effective enough to warrant renting or maybe even buying one? I have 20+small trees/bushes to move on a project and am trying to figure out the most effective way to move these, and to insure their longevity. I have a Cat 257 that would handle one. I am also going to have my mini ex. on the job, but some are somewhat tall and I always seem to tear things up when I use the excavator on larger trees. I am also considering buying one of those tree "scoops" that different manft's have for sale. Thanks for your responses.
