Abstract: Systems and methods which provide motive forces with respect to various apparatuses using self-engaging/disengaging transmission configurations are described. An autonomous-state transmission may comprise a transmission unit configured to autonomously engage and disengage transmission of power from a driving input member to a driven output member without utilization of external gearing or additional mechanical feedback. Embodiments of an autonomous-state transmission may utilize various roller-ramp clutch configurations in communication with override control for disengaging the roller-ramp clutch. The override control may implement various configurations of a skidding mechanism for facilitating engaging and/or disengaging the roller-ramp clutch. According to some examples, motion of the driving input member and/or driven output member is utilized for override force detection and providing override control with respect to the autonomous-state transmission. Embodiments of an autonomous-state transmission may be bidirectionally operative to autonomously engage and disengage transmission of power from a driving input to a driven output.

Abstract: A garden tool, including a main body, a walking wheel mounted on the main body, a self-propelled motor for driving the walking wheel, and a control panel disposed on the main body. The control panel includes a self-propelled control assembly. The self-propelled control assembly includes a self-propelled start paddle and a speed regulating button. Pressing the self-propelled start paddle activates self-propelled operation of the garden tool. The self-propelled start paddle can be released for a short time and the speed regulating button can be adjusted within the short time. The self-propelled start paddle can be re-pressed within the short time and after the speed regulating button is adjusted, and the garden tool maintains the self-propelled operation.

Abstract: A lawn mower includes a blade assembly configured to perform a cutting function. The blade assembly includes an upper blade mounted about a blade rotation axis and an upper blade proximal portion being substantially flat and including a first cutting edge. A lower blade is mounted in overlap with the upper blade about the blade rotation axis. The lower blade includes a lower blade proximal portion positioned outward from the lower blade mounting portion in a radial direction, a lower blade end portion positioned outward from the lower blade proximal portion and below the lower blade proximal portion, and a second cutting edge. A lower blade falling portion transitions from the lower blade proximal portion to the lower blade end portion.

Abstract: A walk power mower comprises a housing having an upwardly and rearwardly extending handle that is gripped by an operator. A load cell is responsive to the force applied by the operator to the handle during a grass mowing operation. Input from the load cell is used by a control system to vary the ground speed of the mower in accordance with the sensed operator applied force through control of an electric traction drive motor.
