Of all the tools a homeowner needs, a lawn raker has to be the most basic equipment to have around the home. To understand why lawn rakers (or scarifiers if you want) are so important, we need to start from the beginning.
In a healthy lawn, it’s completely normal to find some dead plants and grass among the live greenery. This dead grass, roots and moss accumulate to form a thatch which can grow to a few centimetres thick.
Soon enough, the thatch will obstruct the intake of air and water to the roots which will in turn will inhibit the growth of new healthy grass shoots. Before you know it, your once well manicured lawn will be nothing but a patchy shadow of itself.
Raking your lawn regularly is an easy technique used by gardeners to maintain award wining lawns and backyards. For this, we use power rakers or scarifiers which are mower like devices used for efficient removal and collection of thatch.
Using a lawn raker machine is much easier today compared to manual scarification with handrakes. Once a lawn has been raked, fresh grass can have ample space, air and nutrients to grow into a bustling lawn.
When looking for the best lawn raker, it’s important to consider the power source. Petrol powered lawn rakes are more suited for handling larger, wilder lawns while electric models are lighter and quieter for small to medium lawnwork.
Similarly, it helps to choose a machine with an aerator so you can kill two birds with one stone. And if space in the shed is at a premium, you can choose a model that stores easily. A large collection box also means fewer trips to the compost and more time out in the field.
After long hours of intensive scarification on different grass types, lengths, and locations, we’ve compiled a list of the best lawn rakers in the UK market so you can make an informed decision on which unit suits your preferences best.

Lawn Raker Vs Scarifier Vs Aerator
If there’s a group of gardening tools that have people confused, it’s these three right here. But let’s get a few facts straight before we begin – There’s no difference between today’s range of scarifiers and lawn rakers. It’s just that when people refer to rakes, they mean those simple, long, light leaf rakes operated manually.
However, modern lawn rakers are mower-like machines complete with dozens of accessories and functionalities. People in the UK refer to these lawn rakers as scarifiers because, well, we invented the language and will play with it as we see fit.
But for purposes of this article, we will use the terms scarifier and lawn raker as interchangeable. So, what exactly is the difference between a lawn raker and aerator?
This is one of the simplest and least demanding lawn care techniques of them all. It is a completely different process from scarifying, but it also plays a significant part towards improving the health of your lawn.
As the name suggests, aeration involves poking plenty of holes into the soil all over your lawn. This is done to allow fertilizers, water, and air to penetrate more easily through the thatch and into the soil where they can all be easily absorbed into the root system. Aeration is most commonly done early on in the spring or fall when the lawns are still as not heavily compacted.
Most tools meant for lawn aeration typically include long spikes which can either be smooth or cored for pulling out dirt and turf. But unlike scarifiers which pick up after themselves, aerators are simple and usually leave everything either under or on the lawn surface to decompose naturally, or for you clean up.
Lawnrakers or scarifyers involve more intense lawn care. These machines dig into the grass and create slits through your lawn to remove decaying, organic matter beneath the newly shooting live grass.
This is a crucial part of dedicated lawn care since allowing the thatch to accumulate could lead to a dilapidated yard. Thick layers of thatch tend to block out air and nutrients to the root system which can choke out new growth and undermine the health of your lawn.
How do you know you have a thatch problem? Lawns with an undergrowth and thatch problem tend to feel excessively bouncy and springy. And if you try to look through the grass and into the soil, all you see is a confounding mess of dried grass, moss and decaying plant matter.
Of course, it’s entirely possible to scarify your lawn with a handheld rake. But this is a very labour intensive job that is also inefficient as well since you are unlikely to remove enough thatch. Mechanical lawn rakers offer an easier, faster and more accurate way to detach large areas.
Lawn rakers use curved blades or sprung tines to clear out deeply embedded thatch and organic matter from below the surface without hurting the surface grass. What’s more, some machines even come with spikes to aerate the lawn and a collection bag to make quick work of the removed thatch.

This includes a power packed 1100 watt Powerdrive motor for more torque to deal with especially tangled thatch lawns.

The drum uses a Jet collection system to quickly blow up all the dead vegetation and thatch into the practical, large 50-litre sized collection box.

The ALR also makes use of the same Jet collection system to blow debris into the large 50l grass box.

Frequently Asked Questions
Q: How to use an electric lawn raker?
This machine works by teasing the moss and root out of the grass system, and it is fairly easy to use. Simply run it over the grass, having first made sure that the height adjustment is set at the right level.
When you reach the end of the area you are working on, turn around and go back in the opposite direction – don’t go at right angles as this will damage the ground too much.
As you progress and remove the tangles in your lawn you can lower the height of the blades, but try to keep the tines from actually going into the soil as it can damage or even break them.
Q: What is the difference between scarifier and lawn raker?
Both these machines look like a lawn mower, and work in a similar principle – you push them along your lawn to achieve the desired effect. Both are used to improve the health of your lawn and garden.
Lawn rakers have a plastic cylinder that is covered in sprung metal tines, which can pull out moss and thatch from your lawn in a combing action. Lawn scarifiers have the same plastic cylinder, but in their case it is covered with knife blades, which are capable of cutting into the lawn to remove thatch and moss. You can also use your scarifier on its lowest setting, to cut into the soil and improve aeration.
Q: How to change lawn raker tines?
- Remove the roller that holds the tines (there should be a split pin holding everything together).
- Take a small bladed screwdriver and remove the circular spring washer – don’t try to remove the split pin at the other end as it may be much stiffer than the first.
- Remove all but one of the tines – leave the last one is as it will be a guide on how to fit the replacements. Do this by inserting a screwdriver at the base of the tine and levering it off.
- Take your replacement kit (you can get these from a hardware store, your lawn raker manufacturer, or online) and insert the new tines carefully into their holders.
- Slot the plastic circular end back onto the spindle, and replace the end cover plate. Tap it down (lightly!) with a hammer to make sure it is secure.
- Replace the circular spring washer from Step 2, and flatten it down slightly so that it grips the spindle.
- Fit the roller back into the body of the lawn raker and replace the split pin from Step 1.
Spray lightly with WD-40 or similar lubricant oil, to ensure everything runs smoothly.
