I believe the Gen 3 opener is being revealed publically at Ag in Motion. They have a big announcement I have heard.
I think the Pillar is nearly a perfect disc drill for the non-traditional disc drill areas being those that have cold soils in the spring, higher organic matter and lots of residue to seed into. In the years where we were wetter than usual with 60 and 70 bushel stripped rye straw to seed into, it works excellent.
That being said, as it gets drier, the lack of positive seed firming does show up. In low OM, dry soils, there is some inconsistency in closing and packing over the seed.
For this reason since it looks like we are heading into drier days, I bought a Deere 1890 for this year. Now it isn't the perfect drill for all conditions and still takes some learning (I need to not be scared to go deep with the seed) but it seems to do a very good job in the dry.
Hopefully it gets wet again and I have to use the Pillar! As some of you may know, I have Pillar openers mounted on a fold back Case drill so it isn't really worth much. So I bought the Deere toolbar and use the same cart as before. The Pillar will be used for putting fertilizer into grass and probably some grass seeding but will stick around for if I have some problem years again.
The new opener will have the ability to gauge depth beside the disc if desired I think. Then the packer is on a spring loaded arm. They have another new packer wheel profile that is supposed to be the best one yet for seed to soil contact.
I found if I needed to get deeper to moisture, don't be afraid of putting the seed down the disc and fertilizer out the wing. It isn't ideal I guess for placement, but it allows you to go deeper than usual.
