Thought this looked like a really handy mod so I tried it out. I wanted it to me great but, tbh, it's almost more trouble than it's worth. First of all, it DOES work as it's supposed to, which I appreciated. However. The wagon used to build this mod is incredibly difficult to back up. (and I am reasonably good at backing) Since the auger is on the back of the wagon, you obviously have to either back it up to your seeder or back the seeder up to it. If I am in the middle of seeding a field, I don' really want to have to take the seeder to the tender wagon... I mean, isn' the purpose of the seed/fert tender to bring the product TO the seeder? Once again - I LIKE this idea. I would suggest using a platform mod where you could make the auger come out to the side of the wagon. That way you could approach the seeder by driving alone side (or behind) it. Bottom line: Great idea that needs refining.
