Looking at purchasing a DW SK650 for my business which consists of doing all site grading, underground sprinkler installation, seeding, etc. I know these things work great for grading, etc. My question is this: Will this take the place of a dedicated vibratory plow? Currently using a Case Mini-Sneaker, it's nothing too spectacular but it works. I have mainly just trialed these machines with a vib. plow attachment, before I make a final decision I would like some of your guy's input on how these work on the job, pro's & con's for pulling pipe. My plan would be to sell or retire the mini-sneaker. Thanks a bunch!
