The SURTEC NT4551 is an industrial petrol chainsaw built for serious tree cutting, delivering a precise combination of cutting efficiency and operator comfort that suits both working professionals and dedicated homeowners. Powered by a 45CC two-stroke engine producing 1.7KW of rated power at 7500rpm, it delivers steady, predictable cutting performance across a wide range of outdoor applications. Fitted with a 16-inch guide bar as standard and supporting up to 20 inches, the NT4551 is a go-to chainsaw for tree felling, branch removal, forestry work, landscaping, and general property maintenance.

Safety and cutting quality start at the chain. The NT4551 carries a reinforced alloy chain that offers enhanced durability and noticeably reduced kickback, holding a precise, clean line through hardwood and green timber even under tough conditions. An advanced damping system absorbs shock and minimizes vibration, improving comfort and reducing fatigue during long working hours, while the compact, well-balanced design keeps the saw stable and controllable in awkward positions — overhead cuts, tight spaces between limbs, and sloping ground included.

Everyday usability is thoughtfully handled. A clear fuel tank window lets the operator monitor levels at a glance, and tool-free fuel and oil tank caps make refilling simple and fast, so the saw spends more time cutting and less time standing still. At just 5.1KG net weight with optimized balance, the NT4551 is easy to handle all day, and its fuel-efficient, low-emission engine aligns with modern environmental standards — supporting cleaner, more sustainable operation on the job site while keeping running costs down.

For the trade, the NT4551 is a certified, cost-effective platform. Recognized in SURTEC's outdoor power equipment catalog and trusted by garden machinery dealers and outdoor power equipment distributors, the model is backed by professional spare parts that meet both CE and EURO V certification standards. Made from premium aluminum alloy and heat-resistant reinforced nylon, these high-reliability accessories are perfectly compatible with the 45CC NT4551 gasoline chainsaw and suit gardening, agricultural, and light commercial use — an attractive offer for global B2B wholesalers and hardware distributors who value both certification and margin. With steady demand across Latin America, Africa, Eastern Europe, and Southeast Asia, the SURTEC NT4551 is the reliable choice for outdoor professionals who need power, efficiency, and certified quality in one package.
