If you are like me you grow a range of field crops, like wheat, canola, peas etc, but may also row crop beans, gabbanzo, sorghum(milo) or need to lay down fertiliser for your corn, obviously the latter crops are grown as row crop and require much wider row spacing than for wheat etc. Unfortunatley changing your airseeders plumbing isn't that simple. By reducing the amount of openers in the ground you are effectivley reducing the amount of air that can be diffused out of the system, which increases air pressure in your seeders air lines. Excess pressure in your lines leads to poor product placement or "seed bounce" (due to an increase in delivery speed) and in severe cases will cause product to stall in the main lines causing severe blockages. The SeedVU system allows users to maintain airspeed up to the distribution head where the air is seperated from the product allowing gentle entry into the ground and no excess line pressure. So now instead of doubling up your opener's hoses, and double stacking diffusers to deal with excess air, you can simply plug the unwanted outlets in your distribution head, slap in a SeedVU unit and get on with the job in minutes!
