Briggs & Stratton Briggs & Stratton 1227MD Dual-Stage Snow Blower with Electric Start MECH-THROW Error Fix: Won't Throw Snow Far Enough

Error code MECH-THROW on the Briggs & Stratton Briggs & Stratton 1227MD Dual-Stage Snow Blower with Electric Start means: Won't Throw Snow Far Enough. The snow blower picks up snow but throws it only a short distance or the snow dribbles out of the chute. On two-stage models, the impeller clearance is a major factor — the gap between the impeller blades and the impeller housing allows snow to pack around the impeller instead of being thrown. An impeller modification kit installs rubber paddings on the impeller tips to reduce this gap. Ensure the engine is at full throttle during operation. Slow your forward speed to avoid overloading the system. Worn single-stage auger paddles reduce throw distance — replace when worn to the wear indicators. Check the deflector cap angle at the top of the chute.
