The Hayter Harrier 56 is the highest-level striping mower Hayter make for domestic use (3 models available), with a Pro version for commercial purposes.

There are three deck size options with the Harrier range of mowers, and they are identified by the model name shown below. You can also click on the link below, to see my full review of the smaller range of Harrier petrol mowers.
Hayter Harrier 41 – with 41 cm deck size
Hayter Harrier 48 – with 48 cm deck size
Hayter Harrier 56 – with 56 cm deck size
Hayter use their 159cc OHV engines for the basic model and 190cc Briggs & Stratton engines for the advanced BBC and electric start models. Though, all of the above-mentioned engines do little in changing the weight of the machine.
All Harrier 56 engines have the same 1.1 litre fuel tank for regular 4-stroke unleaded fuel. They all use Hayter’s ReadyStart® technology – guaranteeing a first time start of the engine every time. ReadyStart® adjusts the engine’s settings based on the ambient temperature – so, no more guesswork with a manual choke.
The Harrier 56 also has the same options as the Harrier 48. You can get the basic model with Auto-drive, or upgrade to the Blade Brake Clutch (BBC), which protects the engine if the blade hits a solid object. You can upgrade further to the Briggs & Stratton® Electric Start model, and then there is also a Pro version of this mower designed for commercial use. Below, I have created a comparison table to clearly show the differences with the engines and the various features supplied with each of the different models.
Electric Start – Briggs & Stratton’s® InStart® Video
The electric start model is noteworthy as it is supplied with Briggs & Stratton’s® InStart® starting technology. This system is electronic allowing for instant push button starting of the mower, eliminating the need to use the recoil pull start. What makes this system market leading is the lithium-ion battery technology used. The full charge time is just 1 hour and will provide 75 mower starts, plenty for a single mowing session. The other great feature is the ability to do a quick charge of the starter battery for just 10 minutes to get up to 20 starts, this is great if you forgot to charge the battery and just want to get going.
Remember, you also have the recoil start as a backup, if needed.
To learn more about the InStart® system with the Briggs & Stratton® 775iS Series™ engine, please see the video below.
All Hayter Harrier 56 models offer the Sens-a-Speed™ system that automatically adapts to your walking pace from 0 to 2.9mph. This is a really nice feature that ensures that the mower never feels like it is running away from you and saves you having to manually adjust the speed. The Sens-a-Speed™ system is only found on the Hayter Harrier 56 models and NOT on the smaller brothers the Hayter Harrier 41 and 48 models.
- Hayter / Briggs & Stratton
- 159cc / 190cc Engine
- Pull Recoil/Electric Start

Hayter Harrier 56 Video
To give you a visual representation of the Hayter Harrier 56 Petrol Lawn mower please watch the video below:
The Harrier 56 mowers are designed for lawns over 522m². And even though you could use it on much smaller gardens, if you have a smaller lawn you may find one of the smaller Harrier models more suitable. Hayter have included its innovative split two-piece roller on this mower that make turning the approx. 53kgs not only easier but prevents the lawn getting damage whilst turning.
Hayter mowers use their patent-pending Vari-Pitch™ blade technology — this works best on large overgrown and uneven lawns. Vari-Pitch™ optimises the airflow, on high cutting settings, to give your lawn a straight cut and preserve the airflow.
Please note that the Hayter Harrier is also available in smaller deck size for smaller gardens, for my full reviews click the links below –
All four models of the Harrier 56 are self-propelled and can reach a top speed of 2.9mph (3mph for the Pro version). But unlike the smaller models, such as the Harrier 41 and 48, changing the speed of travel is simple. The Hayter Harrier 56 uses something called Sens-a-Speed™.
Sens-a-Speed™ is an automatic system that adjusts the speed of the mower to your rate of walking. If you stop walking, the mower stops. And when you set off, the mower will speed up with you, up to 2.9mph.
In this way, Sens-a-Speed™ is far safer, meaning if you stop or leave the machine to empty the grass bag, the machine will stop moving till you get back.
There are 7 height levels on the Harrier 56, starting from 13mm and rising to 60mm. The position of the lever is conveniently located high on the left rear of the machine, limiting the amount of bending you need to perform to reach it. The number and range of height adjustments compares highly favourably to other brands of high-end mowers, and ensures you can achieve the exact finish you require.
Some mowers I have tested have been disappointing in respect of how difficult the height adjustment can be, particularly on heavier mowers such as this model. I am pleased to say that there are no such problems with the Hayter Harriers, as you would expect this from a company that has been manufacturing lawn mowers for over 70 years.
Vari-Pitch™ also helps the operator navigate and cut areas of long grass, without the need to make height adjustments to the lever.
Deck, Cutting Diameter and Features
Hayter’s aluminium decks are both strong, lightweight, and resilient to corrosion. Plastic decks can crack and degrade under exposure to UV radiation from the Sun. Steel rusts, and in using aluminium Hayter can use their Easy-Wash technology to simplify the deck and blade cleaning process.
The total deck width is 58.5 centimetres and with Hayter’s Trim Side feature means that this mower will cut as close to the edge as possible. The positioning of both the front wheels and the rear roller ensures the blade is able to cut to the outer edge of the mower’s deck to reach the edge of the border fence or wall.
The full range of Harrier 56 has 56-centimetre steel lifting blades, which increases airflow and gives the lawn a better cut. Each side of the deck is a little over 1 centimetre wider than the width of the blade. This means that you can pass close to flower beds and pathways, and still cut most of the grass.
The blade is of excellent quality and should only be replaced with a genuine Hayter blade. Replacement blades are reasonably priced and readily available.

The Harrier 56 petrol mower is fitted with an integrated ribbed roller for making visible and lasting stripes on your lawn. These are dual rollers, to make turning of the mower easier, and will prevent scuffing of the lawn. The roller is the widest rear roller to feature on this class of mower, meaning you get more done for every step you take.
I have tested many petrol mowers over the years that have rollers and claim to stripe your lawn. In order to achieve defined lawn stripes that last, you require a good quality roller and a mower that has a weight that will actually make an impression on the lawn. A lightweight electric mower with a roller will NOT achieve long lasting stripes and will provide no levelling benefit. The high quality of the roller and the approx. 53kg weight (depending on the model) on the Hayter Harrier 56 means that you will be able to achieve that long lasting traditional British striped lawn whilst also levelling small, raised bumps etc. over time. You will be the envy of your neighbours for sure.
It is not just outstanding stipes this mower will achieve. The rear powered roller will also allow cutting to the edge of your lawn without scalping, as the roller will ensure the mower remains level over the edge (not the case with 4 wheeled mowers).
Grass Box Capacity
A 70-litre grass box comes with the full range of the Harrier 56, it is about as large as you would want on a domestic lawn mower before having to use a ride-on mower. The grass box has a metal support frame, which is easy to remove and install. The lid and base of the box are solid plastic, while the sides are good quality mesh fabric.
This hybrid grass box of mesh, metal, and plastic means that you have something rigid for collecting the grass, but flexible enough to fold down for compact storage. Hayter has also made the bag so that you can lift it through the handlebar, for convenience.
Two very well-placed handles on the grass collection bag make emptying quick and easy.
There is no grass box full level indicator on this collection box.
Please note that the grass collection box on the Pro version (579A) is 10 litres larger, compared to the 3 domestic models, at 80 litres.
Easy-Wash is Hayter’s solution to clean the blade and the underside of the deck, with safety and ease. A regular hose attachment plugs into a connector on the deck. Water then flows through to base whilst the blade is spinning, which jets off clumps of grass and dirt. This works similar to a dishwasher.
Keeping the underside of the deck clean means the performance and the cut quality will be maintained over time.
A 4-stroke engine needs a little more caring for than a 2-stroke engine. It is important to deplete the fuel in the tank and the carburettor before putting a mower into long-term storage. It is recommended that Hayter owners should change the oil and the spark plug on the mower after winter storage.
Being a 4-stroke, it is important to check and maintain a good level of engine oil in the machine. Hayter recommends that you bring their mowers to an authorised dealer for maintenance once a year.
You can refer to the Hayter handbook which has a detailed maintenance schedule of what needs to be done on a regular basis.

Both the handlebar and the grass box fold up for when you are putting the Harrier 56 away. Hayter also makes a winter storage cover for the mower to keep it dry, clean, and ready to use when the warm seasons return.
At over 50 kilos, you are going to struggle to lift the Harrier 56, even with a friend. So, if you are considering this model, be sure you have enough floor space in your shed or garage to store it.
For comfort and precision, the Harrier 56 uses Sens-a-Speed™, as automatic throttle control. But with the BBC model, you can disengage the blade shaft from the engine. And with the BBC, you can still use self-propulsion to drive the machine over pathways to other areas of your lawn.
The speed range is 0 to 2.9mph on the domestic range and a single speed of 3mph for the Pro commercial (579A) Harrier.
The Sens-a-Speed™ on the domestic range is a feature that once you have experienced, you will never want to be without. Some fixed single speed mowers often feel they are running away from you. This is fine for commercial purposes as you want to get the job done as quickly as possible, but not so good for home use.
To start the mower, the operator first needs to engage the Operator Presence Control level and then pull on the recoil cord. The electric starting model comes with an ignition key to allow the operator to crank the engine at the push of a button.
The top-end model, the Harrier 56 BBC (575A), allows the user to drive the mower around with the blade motionless, for extra safety and to prevent damage to the blade whilst moving the mower to another location.
There is also a clutch lock on the handlebar, which needs releasing before the operator can engage the blade motor and begin cutting the grass.
The Harrier 56 does not have a mulching blade or plug, but the lifting blade does cut the grass into small clippings. There is also the option of removing the grass box and using the rear lid to redirect the clippings behind the rear roller.
Mowers with rear rollers are not designed to mulch and are not targeted towards those that want to mulch the grass cuttings. Owners of the Hayter Harrier range want a beautiful, pristine and cuttings free lawn, and that is exactly what this mower achieves perfectly well.

Hayter mowers comes with a lifetime warranty on the cutter deck and crankshaft. Hayter also provides a 5-year warranty on material and any factory issues for domestic users.

This 5-year warranty does not apply to those that use the Hayter domestic models for commercial purpose. Commercial users receive a 90-day warranty on the Harrier 56 domestic range. And in both cases, the warranties are valid only if the operator takes their machines to an authorised Hayter service dealer for its 12-month service.
