A rear roller petrol mower does two jobs at once: it cuts your grass and leaves those classic parallel stripes that make a lawn look professionally maintained. The roller flattens each pass of grass in alternating directions, creating light and dark bands as sunlight reflects off the blades at different angles.
Petrol power makes sense if your lawn is larger than about 200m², or if you simply want the freedom of no cables and more cutting force than a battery can deliver. Combine petrol grunt with a proper rear roller, and you get a machine that handles longer grass and delivers a striped finish in one pass.
Short on time? The Hyundai HYM480SPER is our top pick. It pairs a 48cm cut with electric start, self-propulsion, and a genuine rear roller — all for under £400. It handles medium to large lawns with minimal fuss, and the stripe quality is excellent for the price.

The Hyundai HYM480SPER has become one of the most popular rear roller petrol mowers in the UK, and it's not hard to see why. At under £400, you're getting a 48cm cutting width, electric start, self-propulsion, and a proper rear roller — features that would have cost twice as much five years ago.
The 139cc four-stroke engine starts reliably with the push of a button. No yanking a pull cord on a cold morning (though there's a recoil backup if the battery ever dies). The electric start alone makes this worth considering over cheaper alternatives that leave you wrestling with a cord each time.
Cutting performance is strong across the five height settings (25mm to 75mm). The 48cm deck covers ground quickly on larger lawns, and the 70-litre collection bag means fewer trips to the compost heap. The stripe quality from the rear roller is genuinely impressive at this price point — defined, even bands that hold their shape for several days after mowing.
The self-propelled drive works well on flat ground and gentle slopes. On steeper inclines, it can struggle slightly, but that's true of most mowers in this price bracket. Build quality is solid rather than exceptional — the deck is steel, but some of the plastic components (particularly the height adjustment lever) feel like they could be more robust.
Pros:
Cons:
Verdict: The best rear roller petrol mower for most people. It balances price, features, and stripe quality better than anything else at this price. If your lawn is between 200m² and 800m², this is the one to buy.

Hayter mowers have a reputation that borders on cult status among lawn enthusiasts, and the Harrier 41 is the model that earned it. Built in Spellbrook, Hertfordshire, Hayter machines are used by professional groundsmen across the UK — from cricket clubs to bowling greens. This isn't marketing fluff; it's observable fact.
The Harrier 41 runs a Briggs & Stratton 675EXi engine, which is a step above the generic OHV units found in most sub-£500 mowers. It starts cleanly, runs smoothly, and delivers consistent power even in longer grass. The AutoDrive variable-speed system lets you adjust your walking pace rather than forcing you to keep up with or hold back the mower. This makes a bigger difference than you'd expect, particularly on uneven ground.
Where the Harrier truly separates itself is build quality and cut finish. The aluminium alloy deck is virtually indestructible — many Hayter owners report 15+ years of service with basic maintenance. The rear roller produces stripes that are noticeably sharper and more defined than anything in the £300-400 bracket. The 41cm cut width is narrower than some competitors, which means more passes on a large lawn, but the trade-off is better manoeuvrability around borders and beds.
The 55-litre bag is adequate but fills faster than you'd like on larger lawns. At ~£650, this is a significant investment. But viewed as a 10-15 year purchase rather than a 3-5 year one, the per-season cost starts to look very reasonable.
Pros:
Cons:
Verdict: If you're serious about your lawn and willing to pay for a machine that will last 15 years, the Harrier 41 is the one. The stripe quality, build, and engine are in a different league. Buy this if your lawn is your pride and joy.

The Webb RR17SP sits in a sweet spot: it costs roughly £320, yet delivers a genuine rear roller stripe, self-propulsion, and a 43cm cutting width. For anyone who wants striped results without spending £400+, this is the mower to look at first.
The 141cc engine is straightforward — pull start, no frills. It fires up reliably when the mower is properly maintained, though cold starts can require a few pulls in winter. Once running, it has enough power for typical domestic lawns including slightly longer grass, though it will bog down if you let things get truly out of hand.
Seven cutting heights give you good range, from a close 25mm trim up to roughly 75mm for the first cut of spring. The steel deck is sturdy and adds to the mower's solid feel, though it does make the machine heavier than aluminium-decked alternatives. The 60-litre collection bag is a decent size and fills evenly.
Stripe quality is good rather than outstanding. You'll get clear, visible stripes, but they lack the razor-sharp definition of the Hayter or even the Hyundai. For most people, the difference will only be noticeable in a side-by-side comparison.
Pros:
Cons:
Verdict: The best rear roller petrol mower if your budget is tight. It won't match the Hyundai or Hayter for stripe quality, but it produces a clearly striped finish for £60-£330 less than the alternatives.

Mountfield has been making mowers in the UK since 1962, and the SP46 Elite represents their premium domestic offering. The headline feature is the Honda GCVx145 engine — widely regarded as the most reliable small engine in the lawn mower world. If you want a machine that starts first pull every single time for years on end, a Honda engine is the way to get it.
The 46cm cutting width sits nicely between the compact Hayter and the wide Hyundai, making it a good all-rounder for medium to large lawns. The steel chassis gives the mower a planted, substantial feel during use. Autochoke means no fiddling with a choke lever — pull the cord, and the engine sorts itself out.
The rear roller delivers clean, well-defined stripes. Not quite Hayter-level, but close — and the wider 46cm deck means you'll finish striping a large lawn significantly faster. Self-propulsion is smooth and handles gentle to moderate slopes without issue.
Pros:
Cons:
Verdict: The right choice if engine reliability is your top priority. The Honda GCVx145 is the best engine fitted to any mower on this list. A strong pick for anyone who values dependability over features.

The Cobra RM46SPC gives you a 46cm cut, self-propulsion, and a rear roller for around £350. Cobra has built a solid following in the UK domestic market by offering well-specified mowers at aggressive prices.
The Cobra DG450 engine is a 148cc four-stroke unit that provides decent power for domestic use. It's not as refined as the Honda in the Mountfield or the B&S in the Hayter, but it does the job. Starting is pull-cord only, and it's generally reliable once the mower has warmed up.
The 46cm cutting width matches the Mountfield, so you're covering the same ground per pass. The 60-litre bag is a practical size. The rear roller produces acceptable stripes — visible and even, though they lack the crispness of the more expensive options in this roundup.
Pros:
Cons:
Verdict: A capable budget option if you want a wide-cut roller mower without stretching to £400+. It delivers the fundamentals — stripes, self-propulsion, and petrol power — at a competitive price.
Lawn stripes aren't created by cutting grass at different heights. They're created by bending grass blades in different directions. A heavy rear roller presses the grass flat in the direction you're mowing. Walk back in the opposite direction, and the roller bends the grass the other way.
When sunlight hits these alternating bands, grass bent towards you looks darker (you're seeing the tips) and grass bent away looks lighter (you're seeing the reflective underside of the blades). The heavier and wider the roller, the more defined the stripes.
Petrol rear roller mowers tend to produce slightly better stripes than cordless equivalents because they're heavier. More weight pressing through the roller means more grass deflection and sharper stripe definition.
Four-wheeled mowers are lighter, cheaper, and easier to manoeuvre. They handle rough or uneven ground better because each wheel can move independently over bumps. Rear roller mowers are heavier and less agile, but the roller gives you stripes and also helps produce a more even cut on level lawns.
Choose a rear roller if your lawn is reasonably flat and you want stripes. Choose four wheels if your lawn is bumpy and you care more about a clean cut than appearance. If you have slopes, read our guide to self-propelled mowers for slopes and hills.

Yes, but with limits. All five mowers will handle grass up to about 10-12cm without trouble at maximum cutting height. Beyond 15cm, strim it down first or make multiple passes at progressively lower heights. Trying to cut very long grass in one pass will clog the deck and stall the engine.
If your lawn is larger than about 150m² or has any slope, yes. Rear roller mowers are heavier than four-wheeled equivalents because of the roller itself. All five mowers in this guide are self-propelled for this reason.
Petrol roller mowers are more powerful, heavier (which helps stripe definition), and have unlimited runtime. Cordless roller mowers are quieter, require less maintenance, and start instantly. For lawns under 300m², a quality cordless roller mower can match petrol on cut quality. Above 300m², petrol still has the edge. See our full roller mower guide for cordless options.
Honda, then Briggs & Stratton, then own-brand engines (Hyundai, Cobra, Webb). Honda engines are the industry benchmark. The Mountfield SP46 Elite is the only mower here with a Honda engine. Briggs & Stratton (fitted to the Hayter Harrier 41) is a close second.
Petrol rear roller mowers are best suited to lawns between 200m² and 1,500m². Below 200m², a cordless roller mower is simpler and cheaper to run. Above 1,500m², consider a ride-on or cylinder mower. For large gardens, our guide to petrol mowers for large gardens covers wider-cut options.
