It was a fun machine to build. It was a custom design for a Canadian customer. All it does is fill hanging baskets with soil and brushes off the tops of them clean.... then recycles the soil that does not fall into the pots. The customer wanted the whole thing portable and able to fit in a semi truck. Normally things are in a fixed location and shipped on flat beds... The hopper on it holds 9 cubic yards... (a lot of soil) I'm proud of it!
