He Built His Own Grain Drill
"I had the openers for the double disc openers cast to my own design. The hoppers are made of aluminum and clear plastic so you can always see the level of seed and fertilizer. Special-built feed shaft runs the length of the hopper. It feeds out from the entire length of hopper at one time, so the hoppers totally empty out, completely clean. Seed falls from the feed shaft into funnels that separate seed and direct it to the openers. The front hopper is used for seed and the rear one for fertilizer.
"Seeding rate is controlled by an infinitely variable transmission, which I designed. It's coupled to a ground drive wheel. The metering shafts are easily removed or replaced. Special configurations can be machined onto different metering feed shafts for different size seeds or fertilizer so it'll accurately handle everything from tiny bluegrass seed to large fertilizer granules. I made the equipment to machine the metering shafts to various configurations, which are then nickel-plated. The feed mechanism on the drill is patented."
