A harrow is perfect to aerate larger plots of land.

Regular maintenance of lawns and plots is essential to ensuring good fertility and that debris is removed. Build a chain harrow that can be pulled by a lawn mower, quad bike, or a horse that breaks up manure, removes clumps of dead grass that have built up, and prepares the ground for seeding. If your lawn has seen heavy use, use a chain harrow to remove clods of earth that have been kicked up and for aeration of the lawn.

Step 1

Weld an end of the 3-foot pieces of chain to to the end of one of the metal tubes. Weld the other ends to the 5-inch ring. The end result should look like a triangle with two sides the same length. This is the tow bar.

Step 2

Cut the ends of the each pipe, including the one attached to the chains, at a 45-degree angle. When put together, the pipes should form a perfect square. Weld the pipes together.

Step 3

Weld the 4-foot chains to the tow bar 8 inches apart. Weld the other end of the chains to the opposite side. Ensure the chains are tight.

Step 4

Put the first 3 nails through a chain link, 6 inches from the tow bar. Make sure they form a pyramid shape. Each nail should be 6 inches from the other nails in the same pyramid. Weld them onto the chain. Repeat this at 12-inch intervals, working down each chain. There should be 24 of these tines.

Step 5

Attach the harrow to your lawnmower, horse or tractor. Drive at a fast walking pace, to ensure the ground is suitably harrowed.
