This tractor — named Grasshopper — is a walk behind vehicle with an engine that can run on anything! But, is strict about taking ‘only’ anything that’s organic and dry – be it slash from a field, hay, coconut shells or dried food waste.
Congratulations Russell Henning for inventing it! He is a student at San Jose University. An amazing engine finding a use for all that trash, is also a simple and inexpensive machine that can conveniently increase productivity of farmers across the world.
