87521RSX specifications

The Husqvarna 87521RSX is a premium snow blower, designed for residential users who demand efficiency, reliability, and ease of use in their winter maintenance equipment. This powerful machine combines advanced engineering with user-friendly features, making it an excellent choice for tackling snow removal tasks in various conditions.

One of the standout features of the 87521RSX is its robust 208cc engine. This powerful motor provides the necessary muscle to clear snow quickly and efficiently, making it capable of handling heavy snowfall with ease. The electric start capability simplifies the operation process, allowing users to start the machine with the push of a button, eliminating the hassle of pull-starting in cold weather.

The snow blower boasts a 21-inch clearing width and a 12-inch intake height, allowing it to handle large volumes of snow in fewer passes. The adjustable discharge chute can pivot up to 180 degrees, giving users control over where the snow is thrown, which is essential for avoiding piles on driveways or walkways. The chute is also equipped with a manual deflector, enabling further customization in directing the snow.

The Husqvarna 87521RSX is engineered with a track drive system, which offers superior traction on slippery and uneven surfaces compared to standard wheel-driven snow blowers. This feature is particularly beneficial for users with steep driveways or challenging terrain, ensuring stability and control during operation.

For added comfort and convenience, the snow blower features ergonomic handles. The grips are designed for user comfort, even during extended periods of use. Additionally, the snow blower is equipped with LED headlights, providing visibility during early morning or evening snow removal, ensuring users can safely navigate their surroundings.

Built with durability in mind, the 87521RSX features a sturdy steel housing that can withstand rigorous use. This design choice not only enhances longevity but also helps maintain the machine's performance year after year.

Overall, the Husqvarna 87521RSX stands out in the snow blower market for its blend of power, technology, and ease of use.
