Is the back yard going to be set up with raised beds or are you going to be preparing in-ground beds?
For raised beds, I don't till or dig but simply use garden fork to fracture the ground then cover with cardboard and build the raised bed on top.
I also like building mounded wide beds for which I only use sod cutter and spade the sod off the path area, which is piled upside down onto top of the still sodded, garden fork fractured rows, then I mound all the topsoil from the paths then weedy compost, cover with paper, weed free compost and bagged soil, and then mulch. (Basically sheet mulched rows.) No tilling for this either, though some people will till the path to loosen the top soil. I just scrape until I hit the clay subsoil.
