How to use an electric scarifier

If you have a garden with a lawn, suppose you are interested in keeping it in excellent health. Watering it regularly when the sun does not beat hard is undoubtedly good, but it is not enough. You need something else. You need to do the scarifying, and to do it, it is good to have a scarifier available that can be electric, manual, or petrol.


This operation serves to free the lawn from the mulch, that is, the residues of vetch grass and moss. This operation must be done to allow the soil to absorb more oxygen and, therefore, accelerate the lawn’s growth.

When to use the scarifier

Do not be impatient to use the electric scarifier for your parano. Indeed, it is useless to buy it before three years have passed since you put it, and we will immediately explain why. Scarifying removes all those blades of grass with weak roots, characteristic of the young lawn. But suppose that the three years have already passed, let’s see what the most suitable period for the use of the electric scarifier is: the advice is to carry out the work between mid-April and the first week of May because it is in this period that the lawn is in favorable conditions for regeneration.

The correct procedure

When preparing to use the electric scarifier, proceed as follows: the lawn must have already been mowed once, but if there have been two mowings, it is even better. Before using the scarifier, the lawn must be mowed: it is preferable that the grass has a height of 4 centimeters. Finally, it is necessary to make sure that the soil is dry; thus, the device will work more efficiently.

The working depth

To act at the right depth, the scarifier must be positioned on the lawn and, after turning it on, proceed back and forth with small and rapid movements: the depth must be corrected so that the blade cuts only the surface. In general, a well-groomed lawn requires a cutting depth of 3 millimeters. If, on the other hand, the lawn is not taken care of properly, it is better to set the bottom to 5 millimeters.

The correct movements

Again, we need to distinguish between a well-tended and poorly tended lawn. In the first case, it is sufficient to move the scarifier in one direction. If, on the other hand, your lawn is not in excellent condition, you need to go with the scarifier in one direction and then go back. After the operation, the surface will be covered with felt which will be raked and then fertilized if necessary.

Buying guide – How to choose the best electric scarifier?

A scarifier is a tool designed to eliminate weeds and at the same time, make incisions in the soil, without stirring it, so that water, light, and nutrients reach the roots more easily.

On this page, we deal with the electric models made by the best brands, and we analyze all their peculiarities, to provide you with a complete guide that helps you choose the appliance right for you.

The right size

Aesthetically, a scarifier resembles a traditional lawnmower and is therefore composed of an ergonomic handle, an electrically powered motor that manages its operation and a collection tank. When in action, this appliance deals with the removal of moss, weeds, and grass residues, which is also going to affect the ground so that it “breathes” better. That water, Sundays, and all substances penetrate depth, going to feed the roots of the grass or plants.

At the top of the ranking of the assessments to be made, there is, therefore, that relating to the size of your lawn, which will proportionally affect those of the scarifier. A sufficiently large model will allow you to operate rather quickly.

In particular, check how large the roller is, positioned in the lower part of the tool, and responsible for incising and removing the remains and weeds, because it depends on how much soil you will be able to cover with each pass.

It also pays some attention to the shape of the rear wheels. Our advice is to opt for a scarifier that has them independent, since in this way they will prevent the accumulation of grass, ensuring better traction.

Quality materials

We refer both to the materials used for each part and the care in the assembly when we talk about the construction quality of a scarifier. Typically the frame and the handle are made of plastic but ensured by reading our reviews, which convey an excellent feeling of solidity.

The handle must then be ergonomic and allow various adjustments to adapt it entirely to your height, to guarantee a comfortable posture to avoid soreness in the back at the end of use.

The capacity of the container is another essential element because if on the one hand, it affects the handling of the appliance (the larger it is, the higher the weight and size), on the other, in the case of a model with a vast grass catcher, it allows you to only worry about emptying it once the scarifying operation is complete.

Power and depth

An electric scarifier needs to be powered through a power outlet, so check that its cable is long enough to allow you to reach all points in your garden.

Our advice, to obtain satisfactory results, is to direct you to a model with an engine of at least 1,200 / 1,400 watts of power and equipped with a roller whose depth of incision of the ground can be adjusted, always to obtain the expected results.

Many devices are marketed that combine the scarifier function with that of a scarifier. Compare the prices to understand if, in the case of a mode of your interest, the price difference is still within your reach.
