Rear roller vs four-wheel mowers

Side by side

The table shows the general differences between the two designs.

How to get lawn stripes →

Why people choose a roller

The main reason is stripes. The roller bends grass blades in the direction of travel, and light reflects off the bent blades differently, so alternate runs look light and dark. A roller also lets the mower run along a flush path or mowing strip with the roller supporting the back, so the blade cuts right to the edge and you need less strimming.

Why four wheels still suit many lawns

Four-wheel mowers are lighter and easier to manoeuvre. They ride over bumps and dips more evenly, so they are less likely to scalp humps on an uneven lawn. Height adjustment is usually a single lever on all four wheels. For a family lawn where stripes do not matter, wheels are the practical choice.

Most of the mowers in our cordless lawn mower guide are wheeled, with a few roller models for those who want stripes.

Lawn shape and edges

If your lawn is edged by paving, a flush mowing strip or gravel, a roller mower makes edging much easier. If your lawn is edged by raised beds or a drop to a border, the advantage is smaller. Some wheeled mowers, such as the Ryobi models with EasyEdge, have grass combs to help cut close to walls.

Our explainer on lawn edging you can mow over and edging tools has more on getting crisp edges.

Battery and weight

A roller adds weight, and some roller mowers add self drive as well. On a cordless mower, weight affects how easy it is to push and to carry to the shed. The Yard Force 40V 37 cm is an example of a smaller roller mower that stays manageable on a small lawn, while the Hayter Harrier 48 AD is a large self drive roller mower for big lawns.

Which should you buy?

Buy a roller mower if you care about stripes, have flush edges or want to cut to the very edge. Buy a four-wheel mower if your lawn is bumpy, you want the lightest mower, or you simply want a good cut with no fuss. If you have a large lawn and want stripes, combine a roller with self drive.

Height adjustment and cut quality

On a four-wheel mower, height is usually set by one lever that lifts all four wheels together, so changing height between cuts is quick. On a roller mower, the front wheels and the roller set the height together, often with a single lever too, but the range can be narrower. Check the lowest and highest settings against how you like to cut, especially if you leave the grass long in summer.

Cut quality depends far more on a sharp blade and the right height than on wheels or a roller. Follow the one-third rule: never remove more than a third of the grass height in one cut. Our explainer on lawn mower height settings and our one-third rule tool help you pick the right height for the season.

Rollers can scalp the tops of bumps on an uneven lawn because the deck cannot tilt as freely as on wheels. If your lawn has humps, raise the height a notch or level the worst spots with a top dressing in autumn.

Frequently asked questions

Do you need a rear roller to get stripes? For clear stripes, yes. Some wheeled mowers have a small roller or a striping kit, but the effect is lighter.

Are roller mowers worse on wet lawns? Rollers spread the weight but can still mark soft ground. Avoid mowing very wet grass with any mower.

Can a roller mower cut long grass? Yes, but raise the height first and take it down in stages.

Are roller mowers harder to turn? Slightly. You usually tip the mower back on the roller to turn at the end of each run.
