The 5 Best Scarifier For Large Garden – Buying Guide, And Reviews In 2020

Convenient to remove the so-called “felt,” the aerator can be with an internal combustion engine or electric. Two products certainly recommendable are the Al-ko Comfort 38E, multifunctional and powerful, which allows you to switch to the scarifying function without having to change the blades, it has a 55 L collection basket; and the Black & Decker GD300, light and easy to maneuver, one of the best scarifier for a large garden.

Buying Guide – How To Choose The Best Scarifier For Large Garden?

To have a perfectly healthy lawn, it is not enough to regularly cut the grass, but it is advisable to use an aerator. What is it, and what are the aspects to consider before choosing the right one?

We answer these and other questions in this guide in which we have put in a hypothetical classification all the discriminants to be known to decide if it is a device you need.

Maybe not everyone knows that …

As the name suggests, scarifiers are gardening tools that allow you to remove all debris, leaves, and cut grass from a turf that prevents the soil from absorbing the right amount of nutrients and water. Eliminating what in jargon is called “felt” is the prerogative of these machines, which therefore make an essential contribution to the maintenance and beauty of a lawn.

There are specific periods during the year during which to use an aerator: at the end of winter, when the grass is preparing to grow new and luxuriant, or before sowing so that the seeds end up on the ground instead of being “hindered” ”From the felt as mentioned earlier.

Having said when and why to use a scarifier, let’s see now which models are available on the market and made by the best brands in the sector. Typically it is possible to purchase an electrically powered machine and one with an internal combustion engine.

The first lends itself better to be used on not too full grounds because it has the limitation of movement of the cable to be connected to the power outlet. The second does not have any type of travel restriction but is noisier and requires fuel purchases. Read the reviews and datasheets to find the model closest to your needs for the relationship between performance and price.

Build quality

The care in the assembly of the various components and the variety of the materials are unequivocally placed at the top of a hypothetical classification of the conditions that an aerator must-have. Keep in mind that a machine of this type resembles a traditional lawnmower and therefore is equipped with both a frame and a handle, typically made of plastic.

The shell must be studied to resist humidity and heat and to transmit robustness while maintaining a light structure. On the other hand, the handle would be better if it were adjustable, to adapt it to the height of those who will use the scarifier, and ergonomic, for a firmer handle.

Finally, the lower part of the tool is the one equipped with a roller on which a series of blades (of varying numbers and shapes) are inserted, which function as a sort of comb that takes care of removing all debris.

A combined model

In general, to ensure that the scarifier action is effective, our advice is to focus on a model that releases a power between 1,000 and 1,400 watts. It is equipped with a roller that allows the adjustment of the length of the blades.

The best brands also offer models that display dual functionality, combining the capabilities of an aerator with those of a scarifier. By comparing prices, it emerges that these devices are not much more expensive than those that perform a single operation. Therefore they can represent an exciting alternative.

Finally, to ensure long life to your machine, remember to store it in a dry place away from heat sources, to check the condition of the blades regularly, and to empty the container where the felt ends at the end of each use.

Main disadvantage:

The Comfort 38E scarifier offers an additional function that of scarifier, the unique roller supplied. However, according to some buyers is of low quality and tends to wear quickly, mainly if it works on too dry and hard soils.

Verdict 9.7 / 10

It is a model that offers the dual functionality of scarifier and scarifier, easy to use, and excellent quality-price ratio; therefore, it is not surprising that it is among the best sellers.

 Main Features

Dual functionality

To ensure a beautiful, healthy and vigorous lawn, a garden needs a special treatment called scarification, to be performed after the first and after the last cut of the season, to prepare it for both the vegetative and winter phases.

The scarifying of the turf allows it to take on air, light, and nutrients. At the same time, during the summer season, on the other hand, periodic aeration is useful to remove the weeds and debris left after cutting or unwanted accumulations of moss.

The Comfort 38E scarifier, belonging to the Combicare line of scarifiers, produced by the German company Al-Ko, offers the advantage of carrying out both types of lawn treatment, resulting in extremely convenient from the quality-price ratio.

Powerful and easy to use

The Comfort 38E is a scarifier with a compact and clean design, with a light but resistant body. It is powered by a 1,300 Watt electric motor, powered by the popular electrical network via the integrated cable.

The cable, in reality, is short and has the advantage of being fixed to the handlebar frame and ending in a European type electrical outlet, so that it can be connected to an extension without being in the way during work; the handle is adjustable in height and has an ergonomic shape and a coating that improves its comfort and grip capacity, the controls are also placed on the handle, to control the scarifier more easily.

It is equipped with two rollers, the one for aeration has 24 steel springs and a working width of 37 cm, while the one for scarifying has 14 steel blades and is 38 cm wide; the two rollers are interchangeable, of course, and do not require the use of any tools to be replaced.

Practical and functional

The height of the rollers can be adjusted at will on five different levels. This is important for scarifying because it allows you to adjust the entry of the blades into the ground by just a few millimeters, so as not to subject them to intensive wear.

The Comfort 38E scarifier is also equipped with a very comfortable 55-liter volume collection bag, making it even more practical and functional, allowing it to be used even to remove debris and weeds from the garden.

The only flaw of the Comfort 38E, according to the opinions of some buyers, is the scarifier roller, which tends to wear out rather quickly, mainly if used on particularly clayey or dry soils.

 In second place in our ranking, we find what is in all probability the best electric scarifier in terms of quality/price ratio.

It is also equipped with a collection basket, which given the amount of material moved at each step, tends to fill up rather quickly. Therefore, it allows us to carry out the classic aeration operations of the lawn quickly and efficiently in spring (a double pass is not bad) and in autumn, using three different height positions.

How to use a scarifier

The care and maintenance of the garden involve carrying out certain operations at regular intervals that allow improving its appearance and livability. Therefore, keeping the grass at a constant height is not the only action to be carried out with greater or lesser frequency depending on the season. We will have to work so that the earth is always able to absorb the necessary nutrients so that the grass is still green and luxuriant.

Let’s see how to perform correct aeration that allows the soil to renew itself with balance.

Act to break the clods

The scarifier removes the felt that settles on the ground below the surface layer of the grass, together with the remains of the leaves and roots that remain after working with the mower and also the moss that forms with moisture and sun.

To be sure of performing proper maintenance of the lawn, it is necessary to make sure that the layer of dead and non-composted material is removed to guarantee the best permeability of the soil. In this way, water and fertilizers enter deep, feeding the soil depleted by the monoculture of the type of grass chosen for your lawn. Even the robust gramignone that seems to be able to resist any calamity, over time, makes the soil extremely compact, especially in the most superficial layer.

This is because the roots do not go very deep, and these, together with some insects and animals, naturally move the earth and air the earth. Using a machine, you replace natural agents and ensure proper oxygenation and exchange with the outside to receive the fertilizing nutrients you want to treat your lawn.

How often to repeat the treatment

It is unnecessary to repeat the operation of aerating and scarifying the soil with the same frequency with which the grass is mowed. This indeed grows faster than the roots with their horizontal expansion manage to compact the soil. So just choose the optimal period to let the soil get air and do it only once a year.

It is recommended to do this when this is at rest, therefore before the arrival of winter. But depending on the area in which you are located, it may be appropriate to carry out the treatment before the arrival of spring. In this case, it will be useful to ask a local expert for more specific advice.

During the rest of the year, the scarifier can remain comfortably at rest, and therefore, it will be useful to be able to put it away from the weather. The small dimensions of this tool and the possibility of being ready to mount the blades, according to the needs, to scarify or more superficially aerate the ground, simplify the sheltering operation.

What substances are missing from the soil

Oxygen, but also nitrogenous substances and other nutrients, may be lacking in the ground and give a scruffy and battered appearance to the leaves, which will take on the typical yellowish and suffered color of the suffering seedlings.

The right composition of the fertilizer must be chosen based on the type of plant selected for the form of your lawn: has only one kind of seed been planted? Are there areas of shade or more exposed to the action of the sun? And do the plants that grow in flower beds have roots that extend wide or deep? The correct answer to all these questions will allow you to guarantee the most appropriate treatment for your garden’s well-being.
