southern mn | If I recall the back two come from the NH3 manifold where the rest of the 3/8" hoses go to the knives. the front hoses( 1/2") are what is left over from the cooling process I figured they were delivering the same amount of NH3 as the rest of the manifold lines and spread them out across the implement evenly to a shank of their own. Maybe not the way every one would handle them but that"s what I did 20 years ago. | |
