"The John deeres are good drills but I have problems with in a contour situation they are better suited for straight line level seeding"

That's a good point about the JD drill. With the way the front and rear disks are staggered, when you get into contour situations, you can lose your row spacing.  The steeper the slope, the more pronounced this effect is.  Staggering the disks helps with trash flow, but this the negative side effect.
