  • Patent number: 5109930
    Abstract: An earth splitting tool comprised of a central shaft, a handle bar, a foot pressure bar and a wedge-shaped blade is disclosed. The blade has two primary trapezoid-shaped faces, two triangular side faces and a rectangular butt face. One primary face in the same plane as a tangent to the surface of the central shaft. The butt face has a width substantially the same as the thickness of the central shaft.

  • Patent number: 5065567
    Abstract: An improved lawn edger encludes an edging disk mounted for straight line adjustment, on the wheel axle of a lawn mower, between stowed and operative positions. One-handed operation moves the edger between these positions and, additionally, totally removes the edger for close-in mowing. The operating handle extends above the mower deck for ease of operation, while the apparatus minimizes undue tortional forces on the wheel axle.

  • Patent number: 4645010
    Abstract: A combination tool for edging lawns adjacent walkways and the like and for removing the cut strips of lawn. The tool includes a foot plate, an upright elongated handle attached to the foot plate, an edging blade depending from the foot plate for cutting a strip of lawn adjacent a walkway, and a lifting blade projecting from the foot plate having an outer curved end for lifting the cut strip of lawn leaving a desired groove adjacent a walkway. The edging blade is channel-shaped and includes a pair of legs disposed at its opposite ends each having an abutment surface engageable with the walkway for positioning the blade in spaced relation to the walkway when the blade is forced downwardly to edge the lawn. A relief opening is located at each end of the edging blade which prevents the jamming of a strip of lawn between the blade, foot plate and legs. The foot plate also includes a guide surface adjacent the lifting blade which rides along the top of the walkway for properly positioning the lifting blade.

  • Patent number: 4611666
    Abstract: A crack and crevice weeder device for cleaning undesirable growth from cracks or crevices in expansion joints between sidewalks and streets. A V-shaped cutting head is attached to an end of a U-shaped rod and a triangular shaped scraper can be attached to a point on the U-shaped rod. The U-shaped rod is fixed to a long handle which enables an operator, while standing, to remove undesirable growth from cracks or crevices and expansion joints by pulling the weeder towards him, while simultaneously applying a downward pressure.

  • Patent number: 4564072
    Abstract: A garden tool with a tool head (2) comprising a flat blade portion (4) and a soil-deflection portion (5), the latter being located at one end, and to one side only, of the blade portion (4). This arrangement allows the tool head (2) to be drawn along a line to displace soil to one side thereby on the one hand, forming a shallow trench, while on the other hand, piling up earth for earthing up plants. In addition, the top end (4) of the soil-deflecting portion (5) curves round to form a soil scoop. In a preferred form of the tool, the blade portion (4) has working edges (6, 7) enabling it to be used for lawn edge trimming, and a pointed front end (8) which can be used to break up soil.

  • Patent number: 4463544
    Abstract: An edger is provided with a rotatable cutting blade for trimming grass, weeds, and the like, wherein the angular orientation of the cutting blade is quickly and easily adjusted to a selected one of several cutting positions. The cutting blade is driven by a motor mounted within a motor housing which is in turn supported for rotation about a longitudinal axis between a front wheel assembly and a rear wheel assembly. A locking mechanism carried by the motor housing has a pair of spring-biased lugs normally received into locking recesses in the front and rear wheel assemblies to lock the motor housing at a selected rotational position and thereby lock the cutting blade at a selected angular orientation. The locking mechanism is manually retractable to withdraw the lugs simultaneously from their respective locking recesses to permit rotation of the motor housing simultaneously with respect to the front and rear wheel assemblies to alter the angular orientation of the cutting blade.

  • Patent number: 4351395
    Abstract: A one-piece sidewalk edger and lawn trimmer is disclosed. The one-piece edger-trimmer may be attached to a hoe by removable clamping means. The combined edger-trimmer-hoe allows control of the depth of the groove which is made in the ground during the operation of the implement without the need for making a separate adjustment of the implement. The hoe portion scrapes the upper surface of the sidewalk and collects the cuttings which fall upon the sidewalk. A one-piece edger-trimmer-hoe is also disclosed.
