Abstract: A disclosed example scissoring mower includes a cutting assembly driven by a gear system. The mower is moved by an operator or motor to cause rotation of wheels. The wheels are coupled to an axle that drives the gear system and thereby the cutting assembly. Accordingly, when the mower is pushed or driven forward, the gear system causes blades of the cutting assembly to move in opposite directions, creating a scissoring action that cuts grass and other vegetation.

Abstract: A high-efficiency lawn maintenance tool (20) includes a frame (24, 28) and a deck (28) attached to the frame (24, 28). A plurality of ground engaging members (26) are attached to the frame (24, 28), and a power source (34) is attached to one of the frame (24, 28) and the deck (28), wherein the power source (34) is connected to a drive shaft (36) that passes through the deck (28). A high-efficiency blade (56) system is attached to the drive shaft (36). A controller is electrically connected to the power source (34), and the controller is configured to correlate the load and/or the mower (20) groundspeed independent of an operator's control. Other examples include reduced operating speeds of the drive shaft (36) and commensurate reduced tip speeds of a set of cutting blades (56).
