Ariens Gravely ST4 Snow Blower Thrower Parts

ST4 parts and accessories

The Ariens Gravely ST4 snow blower, manufactured throughout the late 20th century, was a popular choice for homeowners and light commercial use. These gas-powered, two-stage machines featured a clearing width suitable for medium-sized driveways and walkways. Known for their reliability and robust construction, the ST4 helped establish Ariens Gravely as a leader in the snow removal equipment market.

The Ariens Gravely ST4 series was a mainstay of their snow blower lineup for many years, offering a balance of power and maneuverability. These models were typically powered by Briggs & Stratton or Tecumseh engines, ranging from 4 to 6 horsepower, with some models offering an optional electric start for added convenience in colder climates. The two-stage design utilizes a powerful auger system to break up snow and ice, feeding it into a high-speed impeller that throws snow up to 30 feet away. The clearing width generally ranged from 20 to 24 inches, with an intake height of around 12 to 16 inches, enabling them to handle moderate snowfalls with ease. ST4 models typically featured a wheel-drive system with multiple forward and reverse speeds, allowing for precise control in various snow conditions. Chute rotation was generally controlled manually via a crank or lever. While features like headlights and heated grips were less common on earlier ST4 models, they were sometimes available as optional upgrades. The ST4 is well-suited for clearing paved surfaces like driveways and sidewalks, and can handle moderate snow accumulations (6-12 inches) effectively. Its durable construction and readily available parts make it a popular choice for homeowners seeking a reliable snow removal solution.

Maintenance Tips

Regularly inspect the auger and impeller for damage or wear. Replace worn paddles or auger flights to maintain optimal performance.
Always use the correct shear pins for your ST4 model. Replace broken shear pins immediately to prevent damage to the auger gearbox.
Check and adjust belt tension periodically to ensure proper power transfer from the engine to the auger and drive system. Loose belts can slip and reduce performance.
Change the engine oil at recommended intervals, typically once per season or after a certain number of hours of use. Use a fuel stabilizer in the off-season to prevent fuel degradation. Adjust the skid shoes to protect the scraper blade and maintain proper clearing height.
