Jackshaft, I'll agree with John on the accuracy of the White planter, there are several guys around here that run them and they rave about the ease of setting them and switching from one crop to another. local Agco dealer just set up a new 12 row White planter with a Morris Air cart. looks like they mate together well! As for the case I haven't been around them at all so I can't help you there. Also, while I've got your attention, do you still have your R-5IJ I've got an N-7 with a similar processor setup (channel bean helicals),and I was wondering how you got along and if your rotor loss was acceptable. Thanks and good luck planter shopping! DAB
