I see where your coming from!

Ideally with a crane you would tip tie everything. But in this case where the crane isn't tall enough, you could butt tie, but that would overload (risk of) the crane. So you would have to rig normally then pick the peices up off the ground with the crane.

Which is what I meant by "pick up big lumps from back gardens". So it would be ok for lifting branches/lumps etc. but not for the actual dismantling of the tree. In my opinion.

Interestign thing to own though!!
