These double-edged replacement HSS blades have an additional two cutting edges, making it them cut in four positions. This extends the life of the blades and facilitates quick replacement. We recommend always replacing the screws when you replace blades. These screws are included in a pack of blades.
During normal use of an Automower the blades will lose their sharpness, and this will become more pronounced the larger your garden is. It is also worth considering that grass is usually damp with morning dew or overnight rain, and there is also an inherent moisture element with grass and clover. This moisture will eventually affect the blades.
These are official, authentic Husqvarna blades, so you know you are getting the best product quality with that famous Husqvarna reliability.
All Husqvarna Automowers are fitted with three blades, so the 6 pack would give you two sets and the 45 pack would give you 15 sets.
