It would have to be that size or smaller. I plan to purchase a used newer model setter that utilizes float trays. It would be based on a design like this yes. You’d still have to put the plant in the cone manually but it would still be a one man operation. With a little modification, it might be converted into a harvester for stalk curing to save some back work. I hadn’t seen this machine. I got the idea from a machine listed on JohnnySeeds after seeing their planter.
