A method of refurbishing a handheld landscape power tool includes separating an original motor of the power tool from a tool head of the power tool. The tool head includes a tool shaft extending proximate to the original motor. A replacement power head and a shaft coupler are provided. The replacement power head includes a motor and a power shaft mechanically coupled to the motor. The shaft coupler includes a power shaft connecter coupled to a shaft-specific connecter. The replacement power head is coupled to the shaft coupler by connecting the power shaft connecter to the power shaft of the replacement power head. The tool head is coupled to the shaft coupler by connecting the shaft-specific connecter to the tool shaft of the tool head.

A handheld lawn maintenance tool having a power head to which an adapter is attachable to allow both battery-powered and gasoline-powered working attachments to be attached thereto. The power head includes a power source, integrated first and second handles, a power generator, and a first attachment mechanism to which the adapter and/or working attachments are attachable.

System for hedge pruning and method for making and using the same. An exemplary system for hedge pruning includes a mounting assembly for connecting to a mobile platform, the mounting assembly defining a pivot point region thereon, a cutting arm rotatably coupled to the mounting assembly at the pivot point region. And a blade assembly connected to an end region of the cutting arm such that the blade assembly prunes a hedge along an arc defined based upon rotation of the cutting arm about the pivot point region. Advantageously, the system provides an ability to discriminate selected plants in a hedge to improve grove health and exploit alternate bearing nature of certain groves, resulting in a more consistent production each year. Differentiated treatment can be provided within a row of the plants while pruning the hedges in an automated manner that is more efficient than manual pruning.

A lawn mower includes a housing with a baffle that defines an air path to produce a cross-flow. The baffle includes a vent to manipulate air pressures within the housing and facilitate movement of plant clippings. A hand-held device for trimming with a rotary blade assembly may also include a housing that defines an air path to produce a cross-flow. The hand-held trimming device may also a baffle with a vent to facilitate movement of plant clippings.

A hand-guided garden, forestry and/or construction working apparatus has an inactive state, an active state and a variable setting, as well as an apparatus operator control element which can be activated by a user. In the inactive state, the garden, forestry and/or construction working apparatus is designed to be transferred into the active state triggered by activation of the apparatus operator control element, and in the active state the garden, forestry and/or construction working apparatus is designed to change the setting and not to be transferred into the inactive state triggered by activation of the apparatus operator control element.

A tree saw attachment for a modular landscape trimmer is disclosed. In one embodiment, the tree saw attachment is provided with a drive unit having a drive shaft operably connectable to a motive source and a transmission operably connected to the drive shaft. An anvil is connected to and extending from an output side of the transmission of the drive unit, and a blade is connected to the output shaft of the transmission. The blade has an arcuate outer peripheral edge with teeth formed along a portion thereof forming a cutting edge so as the output shaft is rotated, the distance between the cutting edge and a central axis of the output shaft increases until the blade has substantially completed one rotation. Rotation of the blade causes the blade to move transversely with respect to the anvil to engage and cut material positioned between the blade and the anvil.

A selection device for pruning machines is designed to select branches or sprouts for pruning performed by the pruning machine. The selection device includes at least one fixing portion adapted for removably fixing to a pruning machine. The selection device includes at least one actuator designed to exert a force upon the branches and sprouts, thus moving them to cause the branches or sprouts selected for the pruning to be arranged in correspondence to cutting elements provided in the pruning machine, hence at least partially preserving the other branches or sprouts from pruning. A frame is designed to at least partially support the at least one actuator. At least one regulating mechanism is fixed to the frame, is associated with at least one actuator, and is designed to regulate at least the direction along which a force is exerted by at least one associated actuator.

A handle includes: a switch lever having an operational portion in an inverted U-shape, and configured to press an on/off switch when the operational portion is gripped and pressed; a handle body provided with the on/off switch mounted thereto and having an inner peripheral slit from which the operational portion of the switch lever housed in the handle body projects; a spring having a supported portion and a pair of arms extending from the supported portion, housed in the handle body, and biasing and pushing the switch lever back; and a plurality of limiters provided at locations in either the handle body or the switch lever at a distance from the spring, and configured to limit movement of the switch lever.

A blade position sensing system for a garden tool is provided. The system includes a driveshaft coupled to one or more blades of a blade assembly. The driveshaft is operably coupled to a motor to selectively rotate the driveshaft relative to a threaded shaft and translate the driveshaft along a linear direction. The driveshaft and the threaded shaft are coupled to one another at a threaded interface. Linear translation of the driveshaft angularly translates one or more blades of the blade assembly. A magnet is coupled to the driveshaft. A proximity sensor is positioned in magnetic communication with the driveshaft. A change in distance between the proximity sensor and the driveshaft changes an output voltage by the proximity sensor.
