Husqvarna 445S 18" Gas Chainsaw — 50cc X-Torq Engine, LowVib Comfort

Designed for homeowners, landscapers and seasonal pros, the 445S balances strong two-stroke power with user-focused features like Smart Start, LowVib dampening and Air Injection pre-cleaning. Its slimmer body and reinforced crankcase make it easier to handle while providing cooling and durability for repeated use during property maintenance, firewood preparation and storm cleanup.

How does the Husqvarna 445S make starting and running simpler?

The 445S uses Smart Start technology and a combined choke/stop control so the engine starts with less effort and is less likely to flood. A clear fuel window shows fuel level at a glance so you can plan refills and avoid downtime.

• Smart Start system for quicker, easier pull-starts
• Combined choke and stop control reduces engine flooding risk
• Transparent fuel indicator for fast visual checks

What performance can I expect from the 50cc X-Torq engine?

The 3-HP X-Torq 50cc engine delivers strong cutting power across common bar lengths while being tuned for fuel efficiency and lower emissions. The included X-CUT chain is designed to hold its edge and provide consistent cutting performance during extended jobs.

• 50cc, 3-horsepower X-Torq two-stroke engine for robust power
• Compatible with bar lengths from 13" to 20" (18" standard)
• X-CUT chain for durable, longer-lasting sharpness

Will the 445S reduce fatigue and feel stable in use?

Husqvarna's LowVib system isolates the handle from the engine using dampeners, which lowers vibration felt by your hands and helps reduce operator fatigue during extended cutting. The slimmer saw body and balanced crankcase design improve control and cooling, making the tool feel more responsive in different cutting positions.

• LowVib anti-vibration system reduces hand-arm vibration transmission
• Slim profile and balanced design for improved maneuverability
• Reinforced crankcase for better cooling and durability

What maintenance or fuel considerations should I know?

The 445S uses Husqvarna two-stroke lubricant mixed at the recommended 50:1 ratio and benefits from Air Injection, a centrifugal cleaning stage that removes larger debris before the air filter. Purchasing qualifying pre-mixed fuel at sale may extend the product warranty, so check current promotions and follow Husqvarna maintenance guidance for longer life.

• Requires 50:1 fuel/oil mix with approved Husqvarna two-stroke lubricant
• Air Injection pre-cleaning reduces air filter clogging
• Warranty extension available when buying qualifying pre-mixed fuel
