The present invention is a string trimmer attachment apparatus and method for easy attachment to a lawn mower deck, without requiring the use of tools for attachment, by having an adjustable trimmer mounting platform which securely attaches to the lawn mower. A string-type powered trimmer motor on the bottom side of the adjustable trimmer mounting platform cuts the grass. An operating control located on the lawn mower controls the string-type powered trimmer motor. A pair of L brackets allow the adjustable trimmer mounting platform to firmly attach to the lawn mower without the need for a separate trimmer/edger appliance. No tools or lawn mower modifications are required to attach the adjustable trimmer mounting platform to the mower deck.

A multi-tired, modular, electronic system which utilizes restricted usage management. In a multi-tiered environment, lower tiered systems contain, based on configuration, mobile units that are capable of performing simple tasks such as lawnmowers, vacuum cleaners, mobile audio/video players to more complex ones capable of performing as human assistants such as robots. Higher tiered systems typically reside in the cloud. Lower tiered mobile units contain modular sensors such as temperature sensor and image/video cameras that generate vast amount of data. The lower tiered mobile units also contain modular emitters that consume vast amount of data. Restrictions for the usage of these mobile units are sent, in the form of metadata, to the lower tiered mobile units, from an intermediate to higher tiered control devices and the rendering app may limit the usage. The intermediate tiered renderer can interact to make sure rules have been followed.

The assembly described herein is secured to lawn equipment for adding additional functionality, such as weed eating. The assembly includes a base having at least one base bracket for selectively coupling the assembly to the lawn equipment. Further, a stem is included having a stem bracket coupled to the base, a stem housing extending from the stem bracket, and a shoulder in rotational engagement with the stem housing. For maneuvering the assembly, an arm is pivotally engaged with the shoulder of the stem and pivotally coupled to the arm actuator. The arm may be radially, angularly and translatably repositioned during use.

A device for extracting auxiliary power from a power source installed on or associated with an implement, and supplying the auxiliary power to an auxiliary tool associated with the implement. The invention is preferably employed in the context of an auxiliary tool, e.g., in the form of a rotary trimmer, edger or the like, associated with another power implement, such as a lawnmower, wherein the power is preferably extracted from a driven member of the implement. Advantageously, the device is easy to attach/detach, is universally locatable and/or orientable on the implement, and is easily retrofittable to practically any existing implement, such as a lawnmower deck.
