How to Make a Homemade Aerator for Lawns
- 1). Measure and mark every 2 inches along the long sides of the 6-by-12-inch plywood. Measure in 1.5-inch intervals along the short sides of the plywood.
- 2). Connect the marks to make a graph on the wood, using the ruler as a straightedge.
- 3). Place the plywood on a grass or dirt surface. Drill a hole through the plywood at each of the 12 points on the graph where the lines intersect with a 5/64 drill bit.
- 4). Drive a 4-inch nail into each of the drilled holes with a hammer. The nails will go all the way through the plywood into the ground.
- 5). Place a metal handle on the board, lining up the screw holes over areas of bare wood. Using the drill with a Philips-head bit, drive the screws into the plywood through the holes to attack the handle.
- 6). Pull the plywood straight up with the handle. To aerate the lawn, place the homemade aerator on a section of grass, step on it to push it into the ground, and pull it up. Repeat until you've covered the lawn.
