These quality blades are excellent mower replacement blades for Ariens Mowers. They are precision balanced and heat treated for durability. We carry different types of blades to choose from including toothed blades, mulching blades and rolled air-lift blades.
Toothed and mulching blades achieve smaller clippings for quick decomposition and a more manicured look.
A rolled air-lift blade lifts grass blades up for a cleaner cut and propels grass clippings up to be sucked into a mower bag easily.
The Silver Streak HiLift Toothed blade are made 25% thicker than most other toothed blades and has 40% higher lift. They have more surface areas to cut grass and leaves and have more sharpening area resulting in longer blade life.
