A powerful lawnmower that’s purpose-built for large lawns

Ease of use

The Harrier 574A might be one of Hayter’s largest domestic lawn mowers, but it’s also one of the most user-friendly machines you’ll find on today’s market. It’s beautifully balanced, which makes it surprisingly easy to manoeuver, and it’s built around a powerful autodrive system that uses Hayter’s Sense-a-Speed to automatically match your pace.

The 574A also makes it very easy to adjust the cutting height, and there’s a special easy-wash system built into the cutting deck, so that you can just attach your garden hose and wash out any loose debris in a matter of seconds.

Best of all though, the 574A has an incredibly high-tech cut and collect system, which uses aerospace technology to cut down on the amount of time you’ll spend emptying out grass clippings, or cleaning up after you’ve finished mowing a lawn.


The Hayter 159cc OHV engine ensures that this mower will power through any large lawn, and a combination of advanced technologies guarantee a professional finish every time you wheel it onto the grass.

Thanks to the wide cutting deck, trim side and forward facing fins, the 574A is also great for edging, and a great all-purpose choice for lawns with lots of obstacles. All things considered, we think it’s one of the best mowers for general purpose maintenance, and it’s reinforced rear roller produces flawless lawn stripes with minimal effort.


The Harrier 574A boasts a die-cast aluminium cutting deck, which helps to cut down on weight and maximise fuel efficiency. The powerful Briggs and Stratton engine also incorporates a variety of fuel saving technologies to reduce running costs, and minimize your carbon footprint.


The Harrier 574A is a robust and reliable mower that’s designed to withstand the rigors of everyday use. It’s cutting deck is made from corrosion-resistant aluminium, the rear roller uses self-aligning bearings and every effort has been made to ensure that durable materials are used throughout.

Hayter have also opted to use a unique cutter blade friction disc – which is designed to protect the engine when you hit a solid object – and there’s a lifetime warranty against camshaft bending, so you don’t have to worry about hitting debris or detritus.

The Harrier 574A comes with a 5 year domestic warranty as standard.
