I know exactly what that is. Its a harvesting machine for an urban garden. These machines are the best. I've seen their larger cousins running around in the fields here in Canada. The shute on the top is responsible for projecting the vegetables into a perfect balistic type arc into the basket. The shute must be swivelled with the greatest of precision to have all the vegetables land in the basket. The proper speed must be selected for the type of vegetable. Potatos are the best they fly the farthest. Carrots tend to get stuck sideways. Tomatos tend to be messy be sure to use a plastic bucket. For the urban garden one must be ready for harvest time. I would recomend highly that you practice first with snow. Now there is some problems with these machines, your neigbour may complain about the noise and smell. And it seems you always have to run at odd hours to get gasoline to practice your evolving technique. But I understand you are a ecorenovator. With your greater skills, remove that motor and install a proper electic motor with batteries. This way you can charge them via your solar panels and practice in stealth mode. The best is your neigbours will be unaware you are preparing your-self for the next harvest season and they won't insist you practice in their laneway.
