Stens High Lift Lawn Mower Blades create a strong suction that pulls grass upwards as it is being cut, which leaves the lawn with a precise and uniform appearance. By pulling the grass blades to stand up straight, the high lift blade can cut them all at the same height for greater consistency. The strong lift capacity of these blades makes them ideal for thick and lush lawns in which the clippings will be bagged.
