I believe because the "Garden Seeder" is just that. It is much lighter duty, uses a much smaller hopper and much less options for seed plates. The "Field Planter" has a large hopper, has dozens of available seed plates and very heavy duty. It also runs a shovel in front of the furrow opener for breaking up the earth and clearing trash out of they way. It is very similar to what is used for larger tractors. Being made by Cole I'm thinking it may have been an off the shelf 4 wheel tractor model that Cole modified to DB specs. If anyone knows about Cole planters maybe they could help me with info.
Before I bought this planter I had already committed to buy a "Garden Seeder" from a gentleman. I should be picking that up soon and maybe I can show a comparison of two.
Regardless of comparison the method of burying the seed itself will always relate back to the seed drill when using a mecanical machine. The variations between different type and sizes states nothing to the method used.
As for your seed drill, it is another rebranded Cole.
I find the best way around this is the call the particual seed drills by the manufacturers brand applied.
If David Bradley call this a Planter, then i would continue calling it a Planter or people will be very, very confused.
