A filament trimmer includes a rotatable trimmer head having an outwardly extending filament. The trimmer has a rear shield and a front wire guard. A cutoff blade is adjustably mounted on the rear shield to move between two different radially inward and outward positions. In the radially outward position, the cutoff blade cuts off the filament at a length in which the filament extends beyond the front guard prior to the filament becoming shortened due to breakage or wear. In the radially inward position, the cutoff blade cuts off the filament at a length in which the filament extends short of the front guard prior to the filament becoming shortened due to breakage or wear.

A filament trimmer includes a rotatable trimmer head having an outwardly extending filament. The trimmer has an upper handle that the operator can grip to operate the trimmer in either a trim mode or an edge mode. In the trim mode, the filament extending outwardly from the trimmer head is positioned in a generally horizontal cutting plane, while in the edge mode the trimmer is reoriented such that the filament is positioned in a generally vertical cutting plane. The upper handle of the trimmer includes dual triggers for selectively starting and stopping rotation of the trimmer head. One trigger is actuated when the trimmer is operated in the trim mode and the other trigger is actuated when the trimmer is operated in the edge mode.

This invention relates to a sprayer having a center boom and pivotal wing booms. The wing booms can be pivoted from an extended spray position to an elevated transport position by lifting and lowering each wing boom about a longitudinal lift pivot axis. In addition, each wing boom can bi-directionally breakaway relative to the center boom by virtue of a breakaway pivot arranged between the lift pivot axis and the innermost end of the wing boom. The breakaway pivot has at least one pair of nested cams that are biased into their nested condition by at least one spring. The center boom carries a pair of support cradles that direct or cam one wing boom forwardly and the other wing boom rearwardly as the wing booms are lifted into the transport position such that the wing booms form an X-shape relative to one another. The support cradles are partially flexible to allow the wing booms to release from the cradles if they strike an obstruction.

A turf sprayer has a truss shaped center boom and a pair of pivotal truss shaped wing booms within which spaced spray nozzles are supported. A drift shroud system comprises three integral and one-piece drift shrouds comprising a center shroud for the center boom and a pair of side shrouds for the wing booms. Each shroud is attached to an underside of the corresponding boom in a manner such that the shrouds project below the booms and not substantially above the booms to leave the truss-shapes of the booms open and unobscured to provide access to the spray nozzles within the booms. The shrouds each have openings in a top wall thereof for receiving the spray exiting from the nozzles with the spray passing downwardly between spaced front and rear walls of the shrouds.

A control system for selectively actuating a component on an outdoor power equipment unit, such as a blade on a lawn mower, uses two separate and distinct operator actions to prevent inadvertent actuation. The control system includes a pivotal bail that must be pivoted from a first component disengaged position to a second component engaged position in which the bail lies flat against the handle assembly of the outdoor power equipment unit. A slide is slidably mounted on a housing, carried on one of the legs of the bail, for movement towards and away from the pivot axis of the bail. The slide must be pushed down to engage the lower end of the slide with a notch in a pivotal cam to temporarily link the cam to the bail in order to actuate the component. When the bail is released to return to its initial position, camming surfaces on the lower end of the slide and the notch are effective to mechanically cam the slide back up to its disengaged position where the lower end of the slide has disengaged the notch.

A low voltage light fixture (10) including a bulb/lens assembly (12) mounted atop an integral post/stake assembly (14). Post/stake assembly (14) includes a hollow tubular portion (20) and a ground stake portion (22). A preferred post/stake assembly (14) is formed from a single piece of plastic, and consists of a pair of elongate legs (94, 96) which are joined to a female adapter (90) through the use of a pair of "living hinges" (100). To assemble post/stake assembly (14), it is merely necessary to draw legs (94, 96) together until a pair of locking fingers (104) extending from leg (94) engage a pair of slots (110) formed in the other leg (96). Light fixture (10) also preferably includes a unique internally ribbed lens which includes a large plurality of internal side ridges (114) and a smaller plurality of top ridges (116). An improved light fixture (10) also preferably includes a pair of integral bulb contact/prong elements ( 84) and provides for aesthetic customization by allowing the selective removal of one of the louvres (32).
