I've used the type that have an electric winch. Worked ok, great for hauling a single bale moderate distances on the road. Not as flexible to use as a bale spike on a tractor loader but in some applications they work good enough. The primary thing that I don;t care for about them is I can't lift the bale ring high enough with it to place over the new bale and you can't get the bale high enough to drop into a hay ring that's already in position.
