i got a old bulldog grafting shovel from car boot,cut blade off and welded it to a piece of solid inch and half steel with a threaded join half way up so it comes apart and fits in quad box.f*****g heavy but a great bit of kit.all the lads up this way use them and they are a godsend on a hard dig.will cut through anything.im sure a few lads on here have seen them in action.
