A mobile platform biomass harvester has a header, a biomass processor, a storage container, a guidance system, an engine, an electric generator, and a guidance system. The header harvests biomass. The biomass processor includes a shredder, a press, a dryer, and a densifier. The densifier compacts the biomass into a multitude of compressed biomass pieces. The storage container receives compressed biomass pieces from the biomass processor. The guidance system guides the mobile platform at a speed determined by the operating capacity of the mobile platform. The engine generates shaft power. The electrical generator converts the shaft power to electricity to power the guidance system.
