After watching several YouTube videos, and also spending time on EveryThingsAttachments and the Piranha sites, I've decided to stick with my original plan of just using the ripper first, then hit it with the stock blade. As much as I like spending money on attachments, with my soil conditions (no roots either) I think the stock blade will do fine, with the rippers help. I feel like I just made some money, having come very close to clicking the BUY button, but not! Doing it as soon as the 4' of snow now there melts will help a lot, I know from planting fence posts in the early spring V. late summer. Late last summer I hand dug a hole to partially bury a 500 gallon water tank, and I was amazed how easy it was, once ripped, easy enough to use a flat nosed shovel, no tapered/pointed one needed.
