Abstract
A high-efficiency cutting system for an autonomous mower provides a multiple blade tip cutting radius for a cleaner cut, and more complete mow. The system includes a spinning blade disk provided within a housing including a vertical standoff. The blade disk includes a first pair of cutting blades located between the center of the blade disk and the circumference of the blade disk, and a second pair of cutting blades located radially inward from the first pair of cutting blades. The cutting blades extend downward and away from the blade disk at an angle.
