The auger and traction drive belts are not adjustable. If the belts are damaged or begin to slip from wear, they should be replaced. It is recommended that the belt(s) be replaced by a qualified service center.

NOTE: It is recommended that both the auger and traction drive belt be replaced at the same time.

TheV-belts on your snow thrower are of special construction and should be replaced by original equipment manufacturer (OEM) belts available from your nearest dealer.Using other than OEM belts can cause personal injury or damage to the snow thrower.

WARNING: Belt replacement requires separation of the snow thrower. While separating the auger housing from the frame assembly, it is important that an assistant stand in the operating position and hold the snow thrower handles. Se- rious personal injury and/or damage to the unit could occur if the snow thrower should fall during the belt changing process.

1130ST specifications

The Husqvarna 1130ST is a powerful and versatile snow blower designed to tackle even the most challenging winter conditions. This machine stands out in the Husqvarna lineup, combining robust performance with advanced technology to make snow clearing an efficient and straightforward task.

At its core, the Husqvarna 1130ST is equipped with a reliable 291cc engine that delivers impressive power. The engine's efficient design ensures optimal fuel consumption while providing the torque necessary for heavy snow removal. This snow blower features a 30-inch clearing width, allowing it to handle significant amounts of snow with ease, while its 21-inch intake height helps it ingest deep snow without bogging down.

One of the key technologies integrated into the 1130ST is its hydrostatic transmission. This feature offers seamless control of forward and reverse speeds, allowing operators to adjust their pace effortlessly while navigating different terrains. The drive system enhances maneuverability, making it ideal for residential driveways, sidewalks, and larger areas that require snow removal.

Another remarkable characteristic of the Husqvarna 1130ST is its two-stage system. The auger collects snow and ice, moving it into the impeller, which then propels it through the discharge chute. This design allows for efficient, high-velocity snow throwing and minimizes clogging, even with wet or heavy snow.

The snow blower’s adjustable skid shoes enhance performance on various surfaces, ensuring that it doesn't damage pavement or grass. In addition to this, the powerful LED headlights improve visibility during early mornings or late evenings, enabling users to operate the machine safely and effectively, regardless of the time of day.

Ergonomically designed controls enhance user comfort, with an easy-to-use dashboard that includes intuitive settings. The handlebars can be adjusted to different heights, providing added comfort for users of all sizes.
