HopperdozerenUK HopperdozerThe hopperdozer consisted of a high-backed sheet iron tray on sled runners and was dragged through grass or weeds containing grasshoppers. As the grasshoppers jumped up and hit the high back, they would fall down into the tray and be killed by a thin layer of kerosene floating on water in the bottom of the tray. |
