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.

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.

A autonomous mobile green area maintenance robot, includes: a first motor-driven treatment tool, a second motor-driven treatment tool differing from the first treatment tool, and an open protective housing with a lateral rim. The first treatment tool defines a first treatment zone and is arranged within the protective housing such that the first treatment zone is located in a safety zone of the protective housing. The safety zone has a safety distance to the lateral rim. The second treatment tool defines a second treatment zone, wherein the second treatment zone is located at least partially beyond the safety zone. The autonomous mobile green area maintenance robot has an autonomous operation mode, wherein in the autonomous operation mode, a maximum kinetic energy of the second motor-driven treatment tool is smaller than a maximum kinetic energy of the first motor-driven treatment tool.

A trenching and edging attachment for a riding lawn mower or compact utility tractor preferably includes a base frame, a cutter drive, a pair of pivoting height wheels and a cutter cover. The base frame preferably includes a lengthwise support member, a cutter support member, two support wheel extensions, a drive support extension, a pivot extension member and two attachment yokes. The pivot extension extends outward from the lengthwise support member and includes at least one retention hook. Each pivoting height wheel includes a wheel roller, a wheel yoke, and a height adjustment device. The wheel yoke is pivotally retained in the support wheel extension. The cutter drive preferably includes a cutter driven shaft, a right angle gearbox, a chain drive and a cutter drive shaft. A drive hub is attached to substantially an end of the cutter driven shaft to retain a trenching blade or an edger.

A trimmer attachment for use with a lawn mower includes a deck mounting plate configured for attachment to the lawn mower, one or more mounting tabs extending up from the deck mounting plate, a curved pivoting arm rotatably coupled to the one or more mounting tabs, a pivoting motor for rotating the pivoting arm, and a trimmer head coupled to the pivoting arm. Rotation of the pivoting arm by the pivoting motor causes the trimmer head to rotate between a stowed position and an engaged position.
