Husqvarna 16-Inch Gas Chainsaw 435 — 40-cc X-Torq, SmartStart and LowVib for Easy Starts

Compact yet powerful, the Husqvarna 435 pairs a 40-cc X-Torq 2-cycle engine with Smart Start and Air Injection to deliver dependable cutting for property maintenance, firewood, and tree trimming. It balances usability and serviceable features — such as a transparent fuel indicator, flip-up fuel cap, and an inertia-activated chain brake — to make outdoor work faster and more predictable. The saw is optimized for 13"–18" bars and is designed to reduce operator fatigue through LowVib dampening.
