i2i,
loads. I found that out when I had to dig a 1m3 drain for my conservatory.
Irving, the old grubbing mattock is a great tool. I used one as well for my foundation and I'm currently digging out a pathway at the back of my workshop with one as well. A mini digger and powered barrow will save you loads of time. Would it be easier to hire an 8yarder to dump the soil into? Try not to copy me and pull the track off the digger. Its a right pain in the arse to put back on.
