The cost of running a combine harvester is much lower than in Ma Lin's hometown.
One combine harvester can easily harvest several dozen acres in a day.
It equates to hundreds of workers, so it's necessary to invent and produce it.
However, it's currently difficult to use it for experiments.
They can judge whether the combine harvester will get stuck with grass blades and identify any malfunctions by cutting grass.
They can test the threshing effect by making fake ears of grain and stalks.
What he is most worried about now is the unreliable spiral structure.
Corn and the like are heavy and have inertia; the spiral structure can push them from side to side.
But stalks are different.
So the effect might not be better than the rotating tracks.
The problem is that it's hard to throw the stalks out when the side-moving tracks reach the end.
Ma Lin hasn't figured out how to solve this problem.
Let's just leave it for now.
Now the issue with enamel wire has become prominent.
