The small harvester looks like a hand-held weed eater. Though in terms of structure and principle, the two are almost identical, and a weed eater can be slightly modified into a harvester, there are still some differences between them.
Especially since this one by Chen Xin is a micro combine harvester with a threshing function, there are significant differences in appearance.
The principle of both is to use an engine to drive blades to cut plant stalks. However, a weed eater needs to adjust the blade height as needed to prevent scalping the lawn, while a harvester requires the blades to be a bit bigger and equipped with guide vanes to better cut crop stalks.
To operate, you just need to start the machine, align it with the crops to be harvested, and push it forward at a steady pace.
This small harvester has wheels and tracks at the bottom, so as long as you hold the handles steady, you can smoothly harvest crops without veering off course.
