Another critical feature is the hydrostatic transmission. This technology allows for smooth and straightforward speed adjustments, offering exceptional maneuverability when navigating around obstacles. The zero-turn radius design is excellent for achieving precise turns, making mowing around trees and flower beds effortless.

In terms of durability, Husqvarna has built these mowers with premium materials, ensuring longevity and reliability even under strenuous conditions. The reinforced chassis and heavy-duty wheels provide stability, contributing to the overall handling of the machines.

Lastly, maintenance is straightforward with these mowers. Accessible maintenance points and a belt-driven transmission reduce wear and tear, extending the life of the machine.
