My Project Last Night
This is the new seeder that I bought. Well...as you can see it is definitely not new...new to me though. It is a Midwest One Way Disc seeder. Actually, it is quite ingenius for how simple it is. As the discs rotate in the soil, a chain (that is currently missing) turns the sprocket that drives the rotors in the seed compartments. As the rotors turn, seed is dispensed into the tubes that are located between the discs. The seed drops and then are covered in soil by the discs. It is so simple and basic and yet fairly clever. The old fellow that I bought the unit from had it for 40 years or so and never used it as a seeder! He had it for working summer fallow. As a result, the shaft was steadfastly rusted and wouldn't turn. Heat and oil and penetrating fluid and a lot of banging and clanging around managed to get it to turn. However, without taking it completely apart I had no idea where it was bound. I finally forced it enough that one of the seed housings broke and then I knew where the problem lay. The good news is that only one assembly was rusted solid...the bad news is that the cast aluminum housing split. Now I have to figure out how to weld cast aluminum (or braise it). I have no idea what to do at this point in time, but I will ask around and figure it out. Once I get the seed housing fixed and continue lubricating the shaft, I will have a usable old seeder for behind the N.
One other fascinating aspect of this seeder is the lifting mechanism. It is a big ole heavy thing that normally the Ford N 3pt. hitch hydraulics wouldn't be able to handle. The lift arms actually hook on to the seeder and when you lift them, a cable and pulley system pulls the wheel at the back of the seeder down, thereby lifting the entire set of discs off the ground. This of course disables the seeding action and allows you to transport the seeder between fields. I will post a picture of the seeder in action once I get it unloaded from the trailer and hooked up to the N.
