Nice to see a 7000 four row planter set up like this. One suggestion. If you still have the insecticide boxes, i filled mine with mason sand in garbage bags to add weight to the planter units.
Does not this seeder seems like a lot of tilling for a no-till approach? I mean it seems like the back roll-up wheels could be more smooth and their spikes are too much.
Those "spiked" closing wheels break up side wall compaction from the closing wheels. You get much better emergence vs the factory rubber closing wheels.
