Professional Performance for the Perfect Stripe The Hayter Harrier 56 PRO is engineered for professional gardeners and homeowners with substantial lawns who demand a flawless, striped finish. At its heart is a powerful 190cc Briggs & Stratton 850E I/C engine, providing reliable power for the toughest conditions.

Advanced Features for a Superior Cut Hayter’s innovative Crank-Safe Blade Brake Clutch (BBC) system is a standout feature, enabling the operator to stop the blade’s rotation without switching off the engine. This is invaluable for emptying the 70-litre grass bag or traversing paths and driveways safely and conveniently. The robust aluminium cutter deck provides exceptional strength and corrosion resistance without adding excessive weight. Combined with Hayter’s unique Vari-Pitch™ cutting technology, which automatically adjusts the deck to increase airflow in longer grass, and an aerospace-inspired blade and deck profile, the Harrier 56 PRO guarantees maximum collection performance. The two-piece steel ribbed rear roller not only creates the iconic ‘Hayter Stripe’ but also improves traction and prevents turf marking during turns.

Maintenance is simplified with an easy-wash hose connector port for cleaning the cutting chamber. Adjusting the cut is effortless thanks to a single lever offering seven height positions, from a low 13mm up to 60mm.

Frequently Asked Questions Who is the Hayter Harrier 56 PRO best suited for? The Harrier 56 PRO is specifically designed for professional gardeners, contractors, and homeowners with large, formal lawns up to 1000m². Its robust construction, powerful engine, and professional features make it ideal for frequent, heavy-duty use where a high-quality striped finish is essential. What is a Blade Brake Clutch (BBC) system? A Blade Brake Clutch (BBC) is a safety and convenience feature that allows the operator to disengage the cutting blade without turning off the mower’s engine. This is particularly useful when you need to stop mowing to empty the grass bag, move obstacles, or travel across non-grass areas like paths or gravel driveways. What are the benefits of the aluminium deck on the Harrier 56 PRO? The aluminium cutter deck offers an excellent combination of strength and low weight. It is highly durable and completely resistant to rust and corrosion, ensuring a long service life even in demanding conditions. This makes it a superior choice over standard steel decks for professional-grade machinery. Does this mower come ready to use? When purchased from an authorised dealer like Sims Garden Machinery, you get more than just the box. For local customers, we provide a full Pre-Delivery Inspection (PDI), meaning the mower is assembled, fuelled, oiled, and tested by our trained mechanics. We also offer local delivery and a full handover. For national deliveries, the mower will be supplied in its original packaging and will require some minor assembly. What fuel and oil does the Harrier 56 PRO use? The mower’s Briggs & Stratton 850E engine is a 4-stroke engine that requires standard unleaded petrol. For engine oil, it uses SAE 30 four-stroke engine oil. It is crucial to use the correct oil type to ensure the engine’s performance and longevity. User Manuals / Downloads View Hayter Brochure
