The Husqvarna 531167901 Snow Blower Impeller Assembly helps propel collected snow through the discharge chute for efficient snow removal performance. Designed as a replacement impeller assembly, it fits compatible Husqvarna snow blowers to work with the auger and discharge system. It works by rotating at high speed to move snow from the auger housing into and through the chute during operation. This supports improved snow-throwing performance, efficient snow discharge, reliable operation, and dependable snow blower functionality.
