GTM 500 SP1 SC H 21″ Self Propelled Petrol Lawnmower

The GTM 500 SP1H is the “dark horse” of the premium lawnmower world, specifically engineered for Irish gardeners who need high-velocity collection without the weight of a commercial tractor. While most competitors in this price bracket use standard single-cylinder engines, the 500 SP1H is built around a heavy-duty Briggs & Stratton 625 E-Series (190cc) engine, delivering a massive 6 HP of raw cutting torque. This single-speed powerhouse features a unique aerodynamic steel chassis that creates a high-pressure vortex, forcing even the wettest, heaviest grass into the massive 75-litre nylon collector. Unlike generic mowers, the GTM Professional series utilizes high-traction “High Wheels” with double ball bearings, ensuring the machine glides over rough terrain while maintaining a surgical 51 cm (20″) cutting path. For the homeowner who wants a “once-and-done” cut on lawns up to 2,000 m², the 500 SP1H offers industrial durability in a maneuverable, walk-behind frame.

• Vortex-Vacuum Steel Deck: The internal geometry of the 51 cm steel deck is specifically shaped to maximize airflow. This creates a “vacuum effect” that lifts grass blades vertically before they are cut, ensuring a perfectly level finish and 100% collection, even in damp conditions.

• “High-Grip” Manoeuvrability Wheels: Featuring oversized rear wheels with deep-tread rubber and double ball bearings at the axle, the 500 SP1H maintains maximum traction on slopes and prevents the “slipping” that often tears turf on heavy machines.

• 3-in-1 Versatility as Standard: Nobody else offers this level of out-of-the-box flexibility. Every unit includes the regular collection bag, a side-discharge chute for meadow-style cutting, and a dedicated mulch plug for organic lawn feeding.

• Single-Lever “Command Height” Adjustment: Forget wrestling with four separate levers. A heavy-duty, spring-assisted single lever allows you to cycle through 7 different cutting heights (25–75 mm) with one hand, allowing for instant transitions between rough edges and fine lawn.

• Heavy-Duty 75L “Dust-Block” Collector: The high-density nylon bag features an integrated level indicator and a specialized weave that traps fine dust and pollen, keeping the operator clean during dry summer mows.

• Integrated “Cockpit” Comfort: The ergonomic handle isn’t just padded; it features an integrated cup holder and a foldable design with quick-release knobs, allowing you to transport or store the mower in the back of a small SUV with zero tools.

• Zero-Prime “ReadyStart®” System: Powered by Briggs & Stratton technology, the 500 SP1H eliminates the need for priming or choking. One smooth pull of the starter cord is all it takes, guaranteed.
