Position the rake with the tips of the curved tines slightly buried in the ground. Grip the rake's handle with both hands.
Pull the rake forward through the grass. Comb the grass toward yourself, stepping back with each stroke as you would when using a common yard rake. The pointed ends of the rake lift the grass and debris, while the flared middle pulls it onto the surface to the lawn.
Comb the lawn in small sections. Repeat the raking process as you move across the entire area to be thatched.
Remove moss from lawns and mulch beds using the same process. Place the curved tines of the thatching rake on top of the moss and pull the rake forward. The tines will lift off the patches of moss.
Collect the thatch in small piles using a yard rake. Rake those piles onto a tarp for disposal. Do not allow piles of thatch to remain on the lawn.
Reseed your lawn using a drop spreader. Pour grass seed into the spreader's hopper. Adjust the controls to set the spread pattern and amount. Each spreader operates slightly differently; some have an adjustable dial while others use a lever. Follow the manufacturer's directions found on the product bag for best application times and amounts.

Water the lawn thoroughly and regularly after thatching, using a garden hose or sprinkler.
