Low Cost Seed Drill for Hard Soil
thingiverse
This manual seed drill was engineered to limit vitamin consumption, relying solely on rope and a PVC pipe, supplemented by an optional coiled metal extension. This project is also cross-listed at www.appropedia.org/Seed_Drill_Punch. Instructions: It was printed with a low fill percentage in order to keep plastic costs to a minimum. For assembly, first insert the seed drill guide into the seed reservoir. Then place a spring atop the guide and push the seed drill plunger through its center. Next compress the spring using the plunger and then thread rope through the tie-downs.
