Take on winter with confidence using the STIHL SFA 120 Battery-Powered Snow Thrower (Unit Only), a premium cordless snow thrower designed for demanding homeowners and light professional users already invested in the STIHL AP / ALLPRO battery platform. Engineered to deliver powerful, consistent snow-clearing performance without the noise, emissions, or maintenance of gas-powered equipment, the SFA 120 combines advanced battery technology with rugged winter-ready construction to clear driveways, walkways, and paved surfaces quickly and efficiently.
Built around a high-torque 36V brushless motor with STIHL CONSTANT POWER electronics, the SFA 120 maintains strong, reliable 2,500 rpm auger performance across a wide 22-inch clearing path and up to 12 inches of snow depth—from light powder to heavy, wet snow. A durable rubber-paddle auger delivers clean surface contact while helping protect asphalt and concrete driveways.
Dual battery bays with sequential discharge let you load two STIHL AP System batteries (recommended: AP 300.0 P, sold separately) that automatically switch over for extended runtime, clearing up to two 6 to 10 car driveways (up to 5,920 sq. ft.) covered with 6 inches of fresh snow. Operators get complete control over snow placement up to 30 ft. away thanks to a 180-degree rotating chute and quick one-handed deflector adjustment, while an ergonomic adjustable folding handle, integrated front LED headlight, and durable skid shoes make operation and off-season storage effortless. Battery and charger sold separately.
Key Benefits
Pro-Grade Clearing Performance - Wide 22-inch clearing path and a high-torque 2.50 kW brushless motor deliver consistent 2,500 rpm auger speed in both wet, heavy snow and light powder up to 12 inches deep.
Dual Battery System with Sequential Discharge - Dual AP battery bays automatically switch from the first battery to the second as it depletes, clearing up to a 6–10 car driveway (up to 5,920 sq. ft.) per charge.
180° Adjustable Chute - Direct snow up to 30 ft. away with a full 180° rotating chute and intuitive one-handed discharge deflector adjustment for fast, on-the-go control.
STIHL Constant Power - Intelligent electronics maintain consistently high auger power throughout the battery discharge cycle rather than slowing down as charge drops.
Ergonomic Folding Handle & LED Headlight - Multiple handle height positions reduce operator fatigue, a forward-folding position makes storage compact, and an integrated front LED light illuminates early-morning or evening clearing.
Surface-Safe Rubber Auger & Skid Shoes - Durable rubber-paddle auger cleans down to the pavement while protective skid shoes help prevent scratching or denting on driveways and walkways.
