Nice links, I love the walls in Lancashire, and Wales. Looks like a lifetime of work.
Heres the little BX23 in action.
Picture of my neighbor Tim rotating the timbers as I inch the stone backwards into the hole. Notice the spacing of the timbers, we where able to guide or steer the stone to a point by varying the spacing, here we are trying to steer it to the right if you looking from the tractor towards my neighbor.
Tim with some extra effort on a 1400 pounder. This i very close to my dragging limits, none of the hydralics would move this one, it was all low range 4X4 with diff lock to skid this up the hill on the plate.
You can get some idea on the size of this monster, it was 23" thick, 60" long and 45" wide, kind of makes my BX23 look like a toy here.
It was getting late by the time we set that monster, I think its coming out nice and will get some shots tomorrow. 4 more monster stones, 1 is about 2000 pounds, and I think I can handle the other 3 with the BX as I think they are a lighter type of stone and range between 700 and 1200 lbs. I still have some smaller sizes to fill in towards the stairs.
