I find that mini's that small are just about useless on most jobs guys get them for. For the price in renting, a 6k or 9k machine can be rented for not much more and will make for much quicker work, with a larger bucket, faster speed, more strength, longer reach. What I have rented a little mini for was a job we did this year, it was a court yard in the center of an office building. We were not able to bring in a larger mini and could only use one that could make it through a 4' door way.
Why do people not respect us as they do other tradesmen? Because every Tom, Dick, and Harry doesn't think he can be a plumber or electrician!
