Yes every machine is designed for a purpose , but you never know a little modification here and there might bring results . I am really impressed by Log Rites gate arch ,Baileys sells them.A light weight tool you can carry in your pickup and move a whole large tree to the curb,logs limbs and all. Now if A guy can only power it besides using a winch to pull it. I have seen kits for powered wheel barrows which run for 8 hrs on a single charge carring 500+lbs.
