Ariens Gravely 939003-ST520E Snow Blower Thrower Parts
The Ariens Gravely 939003 ST520E is a robust two-stage snow blower designed for tackling moderate to heavy snowfall. Equipped with a gas-powered engine and a 20-inch clearing width, this model provides efficient snow removal for residential and light commercial use. Known for its reliability and ease of use, the ST520E was a popular choice among homeowners and property managers during its production run.
The Ariens Gravely 939003 ST520E snow blower offered a blend of power and maneuverability. While the exact production years may vary, it was likely manufactured in the late 1990s and early 2000s. It features a Tecumseh engine, commonly a 5 HP model (specific cc displacement would need to be verified based on the exact engine installed), and was available with or without an electric start option. This is a two-stage snow blower, meaning it uses an auger to break up the snow and then an impeller to throw it through the chute. The auger system features durable steel construction and replaceable shear pins to protect the gearbox. The ST520E boasts a 20-inch clearing width and an intake height of approximately 12-16 inches, allowing it to handle moderate snow drifts. Throwing distance can reach up to 25-30 feet depending on snow conditions. The wheel drive system typically offers 5-6 forward speeds and 2 reverse speeds. Chute rotation is manually controlled, allowing for 180-200 degree direction adjustment. While lacking heated grips, a headlight was often included for improved visibility during early morning or late evening snow removal. It's ideally suited for paved driveways, walkways, and smaller parking areas experiencing moderate to heavy snowfall.

Maintenance Tips
- Inspect Auger and Impeller: Regularly check the auger blades and impeller for wear, damage, or bending. Replace damaged parts promptly to maintain optimal performance.
