I wanted to attempt to write out the big picture of what I hope to develop, especially since this past weekend really helped me start seeing a kind of range of applications that could stem off of the initial infrastructure I've been working on. So, before I start, I'd like to introduce two terms:
On our veggie farm, we use a cold water pressure washer to clean out our plastic harvest bins every week. Nobody really likes the job, and it takes a long time. We have played around with different systems for cleaning them, but none seems ideally efficient.
Roxbury Farm bought a conveyor-belt, self contained bin washer last year. They said it cost them a lot of money, but has some serious "quality of life" benefits: put a dirty bin on the belt, listen to the pressure washer do it's job inside, pick up clean bin from other end.
It occurred to me several years ago that with a standardized bed system, a small grower could benefit from a non-motorized, over the bed platform, to attach row markers, seeders, cultivators, mulch layers, and the like. A 2 or 4 wheeled cart with multiple tool bars would be a significant step up from single wheel hoes or the Weedmaster Weed Master vs. "The Pig" vs. "Scuffles". One or perhaps 2 operators could push or pull an advanced cart design.
