At least one or more trimmer member retention members comprising a pin operatively connected to the head for retaining one or more trimmer members. The pin is positionable within the body portion, movable from a trimmer member retention position to a trimmer release position, such that the moveable pin clears the passage in the trimmer release position, and such that the moveable pin extends across the trimmer member passage in the trimmer member retention position. The pin retention member is configured to extend through an aperture of at least one trimmer member to retain the trimmer member during operation of the weed trimmer apparatus.

摘要： Systems and methods for cutting grass and other materials using a disk-shaped cutting web. The cutting web has a center portion that is attachable to a rotating shaft adapter. The center portion may be a solid annular disk having a keyed aperture that allows it to be mounted on a spindle of a rotating shaft adapter. The cutting web has multiple strings that are connected to the center portion and extend outward from it in a generally radial direction (away from the center of the disk). The strings intersect with each other to form junctions at which they are joined, thereby forming a web that can be rotated at high speed to perform a cutting function. The strings of the web can have sharp or serrated edges and may be colored to increase the visibility of the web.

摘要： A lawnmower accessory assembly includes an extension arm having an inboard end configured for attachment to a lawnmower and an outboard end configured for supporting a trimming assembly operable for cutting or trimming vegetation. The trimming assembly includes a mounting sleeve fixedly mounted on the outboard end of the extension arm, an inner shaft disposed within the mounting sleeve, a rotatable annular pulley secured at one end of the inner shaft and a rotatable trimming disc having at least one trimming member secured at the opposite end of the inner shaft. The pulley of the trimming assembly is operably coupled with a drive pulley provided on the lawnmower by a drive belt such that rotation of the drive pulley in turn rotates the pulley and the trimming disc of the trimming assembly so that the at least one trimming member cuts or trims the vegetation.

摘要： A strand trimmer and method of use thereof. The strand trimmer includes a pair of pivotable arms each having a motor, a follower wheel, and a cutter-spindle assembly disposed thereon. The arms are biased toward one another and are guided by the follower wheels to pivot around obstacles passing between the arms. The motor rotates the cutter-spindle assembly to move cutting strands extending therefrom through a cutting path with sufficient rotational velocity to cut vegetation. The cutter-spindle assembly includes a spool and a strand-feed mechanism. The spool is oriented to rotate about a horizontal axis. The strand-feed mechanism includes a solenoid actuated plunger within a shaft of the cutter-spindle assembly. The plunger engages the spool to control rotation of the spool and thereby feeding out of incremental lengths of the strand.

摘要： An aerodynamic trimmer head assembly for use in flexible line rotary trimmers including a trimmer head having a curvilinear upper head surface and a shroud having a curvilinear portion extending over the head surface. A plurality of ribs extend downwardly and forwardly in the direction of rotation between the head surface and shroud defining a plurality of channels extending between portions of the upper head surface and shroud along curvilinear paths defined by the ribs. The channels define inlet openings in an upper portion of the shroud and outlet openings about the lower end portion thereof. During rotation of the head and shroud, air is drawn downwardly about the drive mechanism, through the channel inlets, into and through the channels and outwardly therefrom at a forward inclination about the line projecting from the housing thereby cooling the drive mechanism of the rotary trimmer and reducing aerodynamic drag on the line.

摘要： A rotary cutting head adapted to allow a flexible strand of cutting wire to be inserted therein has a coupler for coupling the cutting head to a driveshaft of the motor, a support, and a clamping mechanism supported by the support in the rotary cutting head. The clamping mechanism is adapted to clamp the strand within the exterior housing. The clamping mechanism includes squeezing cams mounted so as to pivot in parallel planes therebetween and relative to the rotation axis of the cutting head. The support is axially translatable in the exterior housing. An application of actual movement in a direction opposite to the housing and the support causes a raising of the squeezing cams or a lowering of the squeezing cams.

摘要： A fixed-line trimmer head for a rotary trimmer device includes a housing operatively attachable to the rotary trimmer device. The housing is rotatable when in use around a central axis of rotation and has a top surface extending outwardly from the central axis and facing upward when in use, a bottom surface extending outwardly from the central axis and facing the ground when in use, and a periphery connecting the top surface to the bottom surface. The present invention includes at least one line channel defined within the housing of the trimmer head having an entrance recessed within the periphery and an exit disposed on one of the top and bottom surfaces, wherein the entrance and the exit are each located an equal distance from the axis of rotation. Such as trimmer head is particular suited for preventing dirt and debris from entering a line channel of a fixed-line trimmer head of a rotary trimmer device.
