Learn how to make a homemade broadfork using coil spring harrow tines and some hollow piping. Your new garden tool will make quick work of loosening the soil in your raised beds.
To make this homemade broadfork, I bought two sets of coil-spring harrow tine replacements at the AG-West Supply and drilled two tight holes in a 1-inch-square hollow metal bar, 26 inches long, for the tines to be driven through. Next, I welded hollow pipe — smashed at one end to get a stronger weld — to each end of the square bar. If I were loosening unworked ground, I think I would weld the spring teeth to the square bar, but for working raised beds, the teeth tend to stay in place.
I found two nearly new, long tool handles at a garage sale. I put a small bolt through the neck of each handle and the hollow bar to secure the handles.
I paid $16 for welding, $10 for the garage-sale handles and $15 for the spring tines. The hollow bar was scavenged, 3 feet of the square pipe cost me $6, and the bolts were $1.78, for a total cost of $48.78.
