Dethatching is very important for having a healthy lawn and a lawn dethatcher is the best tool which can solve this purpose. For the purpose of removal of undesired thatch from a lawn a lawn dethatcher is much more efficient and effective than a lawn mower. Using a lawn dethatcher you can also save lot of time and you can significantly improve the look and health of your lawn. A lawn dethatcher usually has a set of four blades, spinning vertically and hitting the ground perpendicularly. For this a lawn dethatcher can remove roots and compacted stems from the top layer of the soil very efficiently. Also moss and weeds, which are bad for the health of the soil, can be removed very effectively.

Step 1 - Determine the Necessity of Dethatching

A lawn dethatcher is a very powerful machine. So it should not be used unnecessarily and when not needed. You can do a small testing on your own to know if thatching is needed or not. Take a small portion of grass and soil from the lawn. Next, measure the thatch layer that is between them. If this layer measures more than half an inch, then thatching is needed.

Step 2 - When to Use it?

You must use the dethatcher at the right time. If the soil is too dry or it is very wet, a lawn dethatcher should not be used. A lawn dethatcher also damages grass and other useful vegetation of your lawn. So dethatching must be done in such a time so that the grass and the other vegetation gets about two-three weeks of proper climate for their recovery. Usually, early spring is the best time for dethatching your lawn. 

Step 3 - Setup

Now before using the dethatcher on the lawn, remove any hard particle or small pieces of rock or pine cones from the lawn. If you want to add fertilizer or any seeds or some other lawn care material, keep them ready and near your hand.

Step 4 - Starting the Lawn Dethatcher

Set up the blade height and spacing. If you set up the blade height or the raking fingers in such a way that they dig deep in the soil then the machine will not work properly and the dethatching will not be very effective. Make sure the raking fingers just touch the ground or adjust it as required. Next fill up the oil tank and check whether the oil is coming to the engine or not. Now pull the starter by setting the choke on. Once the engine is on, close the choke and run the engine for about 1 to 2 minute to warm it up.

Step 5 - Using it on the Lawn

Once the dethatcher is ready for use, go over each area of the lawn and if possible cover the area more than once. For the corners, use a dethatching leaf rake, operated manually. Lastly, put the thatch into a lawn bag for disposal.
