3D-Printed Pedal-Scale Harrow Teeth
 ✖  |
With his first child on the way, Andrew Jossund was already looking ahead to the day he would climb onto a pedal tractor. He began thinking about building implements for it and settled on a harrow. Long before his son was born this past spring, the harrow was finished.
“I had no plans and took no measurements off a real harrow,” says Jossund. “I had my pedal tractor in the shop and tried to find a happy medium between what was accurate to scale, what parts I had available, and what I felt would make a fun toy.”
When finished, Jossund’s harrow was 5 ft. wide, with five 3-bar sections held on with chains like the real thing. He estimates it at about 1/5 scale. The wings fold up into transport position using a crank on the front.
“I got wheels at a local hardware store and fabricated the rest,” says Jossund. “My biggest challenge was the harrow teeth. I wanted something realistic that could make marks in the gravel, but not sharp enough to scratch concrete.”
Jossund’s solution was to use his 3D printer to produce a dozen teeth for each section. He designed them to be held in place with a small machine screw but also snap onto the harrow frame.
“I really enjoyed building this and have more pedal tractor implements in the works,” says Jossund.
