Yes it is a 9430 tractor. Mapping from SCV1 would work,and the drill could be engaged with an implement switch,,,, but we prefer to use a DPST rocker switch to control both the (air drill on/off) and mapping. This way we can still spread seed and fert even if we have to lift the drill in a wet spot. (let the packers press the seed in).Otherwise the drill will stop when we lift the drill.   And sometimes you get to the end of the field and go to switch the drill off, only to find it is already off!!   Did I just shut it off,or was it off all the way.   Just look at the mapping sceen and it will tell you.
