SURTEC NT5251
Portable Gasoline Chainsaw 2 Stroke 45cc Wood Cutting Machine
The SURTEC NT4553 is a portable gasoline chainsaw that packs exceptional performance into a compact, easy-to-handle body — a true 45cc wood cutting machine for operators who want dependable results without the bulk. Its 45CC two-stroke engine provides a steady 1.7KW of rated power at 7500rpm, delivering consistent cutting for landscaping, pruning, firewood preparation, and small forestry tasks. Lightweight and well proportioned, the NT4553 is easy to carry between job sites and comfortable to control hour after hour, whether you are working around the homestead or on a commercial maintenance route.
Dependability starts the moment you pull the cord. The NT4553's easy-start mechanism is engineered for more than 10,000 reliable starts, so ignition stays quick and predictable over years of service. In the cut, a hardened alloy chain delivers durable cutting performance with noticeably less kickback, while the damping system effectively reduces vibration for smoother, more controllable handling. The clear fuel tank window makes level checks instant, and tool-free caps keep refueling and routine maintenance quick — details that add up when the saw is used daily.
The NT4553 is also built with responsibility in mind. Its low-emission, fuel-saving engine reduces both running costs and environmental impact, making it an eco-friendly solution for demanding users who cut regularly and care about the footprint of their equipment. Combined with the compact body and easy-start reliability, this efficiency makes the NT4553 a sensible choice for landscaping crews, orchard and small-farm operators, and homeowners who need a versatile chainsaw that simply works — season after season, without surprises.
For the trade, the NT4553 is a dependable, efficient, and cost-effective line item. Backed by SURTEC's reputation as a leading chainsaw company and chainsaw maker, the model is trusted by chainsaw dealers and outdoor power equipment companies worldwide. It is supported by a full series of CE-certified spare parts that perfectly match the 2-stroke 1.7KW easy-start gasoline chainsaw for gardening, agricultural harvesting, and light commercial cutting — high-strength components in lightweight aluminum alloy and reinforced nylon that balance durability with comfort and move fast for global B2B wholesalers and hardware distributors. With steady demand across Latin America, Africa, Eastern Europe, and Southeast Asia, the SURTEC NT4553 gives dealers a compact, proven, easy-to-demonstrate wood cutting chainsaw that builds repeat business.
