The size of the seed is very different. When the crops are different or the seed varieties are different, the grain size changes. Or by converting between the on-demand state and the hole-casting state, it has been solved for many years by replacing the seeding trays that match the size of the seeds to be planted, and needs to be stopped for disassembly, which not only increases the operating cost but also delays the farming. Hey, it is easy to lose after being taken care of.
