I bought a used Rip and Dig a few months ago and it is a beast. It'll dig a hole and ditch and tear up the ground as advertised.
It's much bigger and heavier ( a good thing) than I thought it was going to be. I don't believe it can be destroyed. I've owned a couple of Ratchet Rakes (I got a bigger tractor so had to get bigger Ratchet Rakes) and it's the implement I don't trade or sale as the Rip and Dig will also be.
