7021RES specifications

The Husqvarna 7021RES is a standout among self-propelled lawn mowers, designed to deliver exceptional performance and efficiency for homeowners looking to maintain their lawns with ease. This powerful gas-powered model is equipped with a range of features and technologies that enhance its functionality and user experience.

At the heart of the Husqvarna 7021RES is a robust 160cc Honda engine. This reliable engine provides ample power to tackle various grass types and terrains, ensuring a clean and precise cut every time. The engine's design promotes fuel efficiency, allowing homeowners to mow their lawns on less fuel, which is both environmentally friendly and cost-effective.
