It's breathtaking how large a stone can be hu-manhandled into place without having to bring some big noisy machine on site and then stand around and watch it take all the fun out of the job.
This large 'tree dolly', which was specially designed and refitted with a thick metal plate to slip under boulders, does a great job of moving boulders. It's quiet and doesn't fill the air with diesel smoke. The things it can move with a little tugging and grunting is indeed 'breathtaking'.
