The Mighty Wolf

Auto spade, does it do the digging itself lol :-)

For the price that these go for nowadays, you'd expect it to !!

I didn't believe you so I just looked up on google. What if you want the dug soil on a tray to the side and not fired forward?

Dunno, never used it, but they're a legend on the allotments apparently.
These range from £25 up to £100 (depending on new/used/postage costs etc).
Have a look on ebay, one minute they're giving them practically away, the next there's a bidding war...
