Honda GXV160 Commercial Petrol Engine
The lawnmower is equipped with a Honda GXV160 engine, built specifically for professional and heavy-duty domestic applications. This four-stroke petrol engine is engineered for easy starting, fuel efficiency, and quiet operation while maintaining the power output necessary for challenging grass conditions. A front protection bar secures the engine against accidental impacts during transit or operation near obstacles.
Upgraded Heavy-Duty Rear Roller Assembly
The V2 model features significant design improvements to the rear roller system to ensure longevity in professional environments. The upgraded assembly incorporates a new bearing configuration with specialized ratchet bearings that actively prevent water and debris ingress. This engineering update reduces required maintenance intervals, ensures smoother rolling action, and protects the internal mechanism from premature wear.
Shaft-Driven High-Speed Gearbox
Unlike standard belt-driven mowers, this model utilizes a robust shaft-driven system to transfer power directly from the Honda engine to the high-speed gearbox. Mechanical shaft drives provide positive, high-torque propulsion without the risk of belt slippage or breakage in wet grass. The high-speed transmission allows operators to maintain high ground speed and productivity across large properties.
Cast Aluminium Deck and Reinforced Liners
The 53cm cutting deck is constructed from heavy-duty cast aluminium, offering a lightweight structure that is naturally resistant to corrosion from grass acids and moisture. To handle regular wear from stones and debris, the deck features a reinforced internal liner. The structure is completed with thicker gauge handlebars to provide extra rigidity under the daily mechanical stresses of commercial mowing.
Fan-Assisted Grass Collection and Cutting Control
To ensure clean collection even in damp autumn conditions, the mower uses a fan-assisted collection system that forces clippings upward into the large 75-litre fabric grass bag. A Blade Brake Clutch (BBC) mechanism allows the operator to stop the cutting blade from spinning while keeping the engine running. This allows the grass bag to be emptied safely without restarting the engine, and permits driving the mower across gravel paths with the blade disengaged.
