I was thinking about one of these a couple of years ago and stopped short due to the pricing in my area. Now with knowing NT has them I will consider one again.
I had a similar problem with a landscape rake on my B2410. By connecting the upper link to the other hole (I think it was the lower hole) on the attachment point of the tractor you get more lift. This is described in the manual on what hole to attach to. Your tractor is probably the same. This gave me about 6 inches more of lift. For other implements you go back to the original hole attachment point.
