I posted a while ago about tractor-mounted vibratory plows, and since then I have found a few that run about $12k for one that goes on a 3 pt hitch. That seemed like too much money, so we took a chance and pinned a used ditch witch blade onto a bracket that can mount to my tractor. All for about $400. The thing works pretty well, pulling pipe through the ground about 6" deep. Now, I am not expecting this thing to work on large commercial sites where the spec is >8" deep, but I think it will be good for residential. We pulled some pipe around my yard, through rocks and roots, and the thing was super. I plan on using it for residential stuff next year, but I want to know if you guys can foresee any problems with not having the blade vibrate. Am I setting myself up for problems with large gouges in the pipe since there is no vibrating to loosen the soil? What are your thoughts? By the way, the pipe looked good after it was pulled into the ground, we took it out and inspected it, but I know that the guys on this board have a lot of knowledge. Is there something that we didn't consider?
