Lawnmaster Gladiator Pro 21: Built for Professionals. Perfect for Perfectionists.

Take your mowing to the next level with the Lawnmaster Gladiator Pro 21, a commercial-grade powerhouse engineered for serious performance. Whether you’re a professional landscaper or a discerning homeowner, this premium petrol mower delivers the cutting power, precision, and durability you need for a flawless finish—every time.

Unmatched Performance for Demanding Lawns

At its heart is a 224cc commercial-grade 4-stroke engine—robust, smooth-running, and built for heavy-duty performance. Designed to handle large lawns and frequent use, it offers reliable starting, low-maintenance operation, and plenty of torque to deal with tough grass.

A 53cm (21-inch) cutting deck means fewer passes, faster results, and immaculate coverage across expansive areas.

Key Features at a Glance

  • ✅ Pro-Spec 224cc 4-Stroke Engine – Delivers dependable power and quiet, efficient performance for heavy workloads.

  • ✅ Three-Speed Drive System – Choose from three forward speeds to match your pace and mowing conditions perfectly.

  • ✅ Tough Cast Aluminium Cutter Deck – Lightweight, corrosion-resistant, and virtually indestructible.

  • ✅ 70-Litre Grass Collector – High-capacity collection bag with dust-blocking top and side cover for cleaner operation.

  • ✅ 9 Cutting Heights (10–66mm) – Achieve the exact finish you want with simple, centralised height adjustment.

  • ✅ 8-Inch Soft-Compound Wheels – Offer superior grip and stability across varied terrain.

  • ✅ Self-Propelled for Easy Use – Let the mower do the hard work, even on inclines or uneven ground.

  • ✅ Folding Reinforced Handles – Dual-arm steel supports increase rigidity; fold down easily for compact storage.

Engineered for the Long Haul

The Gladiator Pro 21 is built with professional-grade durability in mind. The cast aluminium chassis resists dents, impacts, and corrosion, while the eco-friendly powder-coated finish keeps it looking sharp year after year.

Inside the engine, a cast-iron cylinder sleeve and crankshaft extend service life, making it ideal for long-term, high-frequency use. A lightweight flywheel and soft-grip recoil starter make cold starts a breeze, while the low-vibration, low-noise OHV engine ensures comfortable operation over extended periods.

Warranty You Can Count On

Enjoy total peace of mind with Lawnmaster’s industry-leading warranty:

  • 5-Year Domestic Warranty – Subject to annual servicing.

  • 2-Year Commercial Warranty – For contractors, landscapers, and professional users.
