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.
