摘要： This invention relates to configurations that leverage thrust-based forces derived from mower blade aerodynamic surfaces as control inputs to the motion and position of the blade in three-dimensional space. Properly configured, the invention results in solutions that provide: a thrust-enabled continuously variable cutting height with top-down mulching, a mower configuration that allows an electric motor/blade assembly to move up and down relative to the ground (z-axis), a thrust derived from aerodynamic surfaces of curved mower blades that causes force vectors in the z-axis with resulting up and down motion of the motor/blade assembly, and use of mechanical springs (including spring washers, torsion springs, shock absorbers, elastic materials exhibiting spring-like behavior, etc.) to oppose the thrust-based force vectors as a dampener to limit motor/blade assembly vertical range of motion in the z-axis, and a range of motion is calibrated to specific property and grass specifications.
