Thanks for taking your time to read our information and reviews on the best rotary lawnmowers on the UK market. Rotary mowers are currently the most popular type of mower on the UK market. A rotary mower is a lawnmower with a single blade on the base of the mower, that spins around and cuts the grass.
Rotary mowers are without doubt the most popular and versatile mower type. That is simply because they can cope with most types of grass, lawns and garden types. They are more popular than cylinder mowers or hover mowers.
Rotary mowers are easy to identify as they will have 4 wheels. If you look underneath the mower you will see the single rotary blade. This blade actually chops grass and although it is an effective method of cutting, it is actually quite a crude method.
That is why you may have noticed that cylinder mowers are used on grass surfaces such as bowling greens, cricket pitches and golfing greens. However, the majority of home owners simply want a fast and effective method for cutting their grass a few times a year. The rotary mower does just that.
The majority of this type of motor are powered by electricity. There are some rotary mowers that are petrol driven.

Rotary Lawnmower Buyer's Guide
We always like to provide a buyer's guide as that can be very useful when it comes to buying any product. Just below we explain the most important issues that you should consider when buying a rotary lawnmower.
How Much do Rotary Lawnmowers Cost?
At the lower end of price points, for a basic rotary mower they cost around £70-£80. At the higher end of the price points they can cost between £180-250. So why the big difference?
The more expensive rotary mowers have a better design and better engineering. They will have larger and more powerful motors, larger cutting widths, noise reduction, ergonomic handles, larger grass boxes and will be easier to store.
For example a basic mower will have a 32 cm cutting width, a 1200 watt motor and a 40 litre grass box. One at the higher end with have a 46 cm cutting width, a 1700 watt motor and a 50 litre grass box, along with other features.
Petrol rotary mowers cost between £150-250 depending on the brand and engine size.
Motor Size is Important
For any rotary mower that is powered by electric, the motor size is an important consideration. This is measured in watts, so when looking at that, you will see something like 1200W. That would mean that particular mower is a 1200 watt motor.
The motor is what drives the blade around, and is also what dictates the speed of the spinning blade. Rotary mower motors can vary in size from 1,000 to 1,700 watts. The general rule of thumb is the larger the motor, the easier it is to cut your grass.
You certainly need a larger motor to cut longer grass, or larger areas of lawn. Larger motors are stronger and perform better, without over heating and cutting out. A larger motor will also last much longer than a smaller motor size.
For larger gardens (over 750 square metres) we would recommend a petrol mower or some form of ride-on mower rather than a rotary option.
This is simply the width of grass that a mower can cut in one single pass. This is measured in centimetres. Rotary lawnmowers come in many different width sizes ranging from 32 cm to 47 cm. The larger this cutting width the faster you will be able to cut your grass, simply because you can do a wider area with each pass of the mower.
All rotary mowers have cutting height ranges. This refers to the amount of grass that you want to leave on your lawn once it has been mowed. These heights can range from 20-80 mm (0.8" to 3.15"). The recommended height of grass for fine lawns, is around 6-13mm (¼-½in). For ordinary lawns this will be 13-25mm (½-1in) in summer and up to 40mm (1½in) in spring and autumn.
This is why you need to have various heights on your mower. On the cheaper and basic rotary mowers you need to change the height by manually moving the wheels into different slots. On the more expensive models, this is achieved by clicking a button and moving the mower up and down.
Grass Collection Box
All rotary mowers will have a grass collection box. The mower shoots the cut grass from the blade into this box. The size of the grass collection box will determine how often you need to empty it when cutting your grass.
These vary in size from 40 litres to around 55 litres. The bigger the box, the less trips you have back to your waste disposal bin. In the more expensive models, these boxes will have an indicator as to how full the box is. They will also be foldable which makes the mower smaller to store away.
The boxes which don't fold are usually made of a hard plastic and hook on to the mower. The foldable boxes usually have a plastic top and bottom, but the sides are made from a mesh, which is easy to fold.
Ease of Assembly & Maintenance
When you first receive your mower, there is usually some assembly required. This can take between 15-30 minutes to do depending on the model of rotary mower that you buy. This can involve assembling the grass box, putting the wheels on and assembling the handle. This is a one-off assembly and depending on the instructions can be simple or a real pain.
Rotary mowers do not need a lot of maintenance. They should of course be cleaned and dried off after each use to keep them in the best condition. (In reality few people do this, but they really should) The biggest weakness in a rotary mower is damage to the blade.
Ideally a blade should be sharpened a couple of times a year. This is an easy task to do, but again most people don't honestly know how to do this. It can be done using a knife sharpener, a metal file of a small grinding wheel.
Sticks and stones can also chip the blade and that will greatly reduce its effectiveness. The blade should be replaced when it gets damaged and these are cheap and easy to replace with a screwdriver and a spanner.
Petrol Rotary Mowers
Petrol rotary mowers are a whole different beast when compared to an electric rotary mower. The blade and grass box etc all serve the same purpose. the difference is that an engine powers the blade rather than an electric mower. There is no doubt that a petrol driven mower will power through grass cutting much faster than an electric version.
Petrol mowers do not have a power cable, and that means you can reach further into the garden, and you can also take it anywhere without having to think about how close you are to a plug socket. They can handle long and dense grass, and they are very durable as they have a petrol-powered engine and high-quality design.
On the other hand, petrol mowers are also heavier to move around, and they do need more ongoing maintenance. There will be maintenance tasks such as cleaning the air filter, changing the oil, checking the condition of the drive belt etc
Rotary Mower FAQ
Just below we have answered the most frequently asked questions about rotary mowers by buyers.
Rotary mowers are used for general grass cutting. Cylinder mowers are better for precise grass cutting, which is why you will find they are used on bowling greens, cricket pitches and decorative lawns. The cylinder mower uses sets of blades which cut the top of the grass and as such will not cause any tearing of the grass. Rotary mowers however use a single hardened steel blade which basically chops the grass. The rotary mower will be much faster, but not as forgiving to the grass.
Hover mowers use a cushion of air to keep them off the ground, whereas rotary mowers use a set of 4 wheels to do that. Both types of lawnmower cut the grass from above using a rotating cutting disc or blade. With a rotary, your only option is to cut the grass in straight lines. So if you like stripes on your lawn, the only viable option is a rotary. The hover allows you to mow the grass in any direction, and is also much easier to move around. Hover mowers are usually better for irregular shaped lawns. Also because they are lighter, they are better for using on lawns with slopes.
It is honestly a matter of personal preference. For the vast majority of home owners, a rotary mower is perfect for their gardens. For very keen gardeners who want a "perfect lawn," they will usually use a cylinder reel mower as it is much better for the grass. They do take more time to use, but a keen gardener will not mind that. Home owners with very large gardens will more likely opt for a petrol mower or even a ride-on mower. There are of course the technically minded people, who will simply use a robotic lawnmower, and let that do all of the work for them.
Some models do have a back roller and some don't. The purpose of a back roller is to help create stripes on their lawn. Trying to achieve that without a roller is close to impossible. It also depends on the type and height of the grass, but the roller is what shapes the grass in different directions and creates stripes. If that is the look that you want to achieve, then be sure to buy a rotary mower with a roller at the rear.
