When you want to speed up the tilling process in your garden but can't afford a tractor plow, try constructing your own plow out of a few simple products. You need some wood, two single-pronged cultivators as the plow blades and a few other supplies. You'll be able to use the weight of the plow frame combined with your pulling power to till your garden's soil in preparation for mulching and sowing seeds.
Saw six pieces of 2x4 wood to 38 inches in length. The typical garden row is plowed 36 inches apart, so you'll want to build your garden plow at that spacing.
Construct a plow frame. Take two of the 2x4s and lay them parallel to each other. Take the additional two 2x4s and lay them on top of the other two to create a box-shaped frame. Screw all the pieces together using four screws at each of the four joints.
Take the final two 2x4s and place them together forming an "X" to hold the frame securely in place. Hold it up to the frame and mark with a pencil where to trim one of the pieces of the "X" so that it will fit snugly inside the frame. Saw it to trim it, and install inside the frame using two screws on each end through the frame. Place the longer portion of the "X" crosswise on the frame over the other crosswise piece, and screw into place.
Complete the plow construction. Place the two plow blade (one-pronged cultivators) handles on top of the frame with the blade prongs pointing down and in toward the ground. Position them so that the frame is as close to the blades as possible without touching any metal. Apply wood glue to the entire length of plow handles where it touches the frame. Secure by drilling screws every two inches through the plow handles and into the two vertical pieces of 2x4s.
To use your garden plow, hold the plow handles with the plow in back of you and the blades pointed down to the ground. Walk forward, dragging the blades into the soil. The weight of the frame and blades and pulling the plow will work together to plow the soil.
