The Grain Harvester by Isabela Factor
How does the invention work???
It cut the grain for the farmers, though they has to follow it in order to bind the grain. After binding it they had to load it onto a wagon and have it delivered to a stationary threshing machine, which seperated the grain kernel from the plant. The binding had to be completed so the reaper could turn around and start a new roll.
