Combines 915 corn head question

I have to agree a four row wide head will just

JB, I have no personal experience with this(for 2 reasons, 1)IH conventionals are about as rare as hen's teeth around here and 2) Back then, everybody had wide rows) but my IH Buyers Guides from 1974-77 all list a 4RN head as an option on the 915, as well as a 8RN as well(no 8RW, though),so I would think that there is some way to do it with some sort of tire setup. As far as yield monitors, I don't know of anybody that offers one for the old 915s. Hope this helps.

I am thinking the same thing you are about cornheads. I bought a 4 narrow head for 20% of a 6. I calculate that running over 5 mph will get the same done as running 3.5 with the 6.
