  • Patent number: 8074435
    Abstract: A grass cutting device operable to sever at least a portion of a blade of grass wherein the grass cutting device utilizes stationary blades and is slidably traversed across a lawn. The grass cutting device further includes a bin having a plurality of walls configured to receive and store grass clippings therein. Operably coupled to the bin proximate the front wall is a clipping guide member. The clipping guide member functions to transfer grass clippings from the blade assembly into the bin. The blade assembly is mounted to the clipping guide member distal to the bin. The blade assembly further includes a plurality of triangular shaped blades with alternately intermediate dividers. The dividers function to partition a section of grass of a lawn into a smaller portion as the section of grass enters the blade assembly in order to facilitate severing of at least a portion of the blades of grass when contacted by the plurality of blades.

  • Patent number: 7652438
    Abstract: A drive arrangement for a hand-guided working machine for agriculture, forestry and horticulture applications. The drive arrangement comprises an electric motor, a DC power source for electrical energy, and a control apparatus for the electric motor which is fed from the DC power source. The electric motor has a specific, in particular linear, characteristic curve between the electric current which is consumed by the electric motor and the rotational speed of an output shaft of the electric motor. The control apparatus has current-limiter which limits the current which flows through the electric motor to a maximum value in order to protect the electric motor against overloading. The control apparatus limits the current consumption of the electric motor in a range of low rotational speeds to values which are considerably smaller than the characteristic curve values which are given for these rotational speeds by the characteristic curve of the electric motor, as a function of the rotational speed.

  • Patent number: 5937626
    Abstract: A hand-held device for picking fruit which includes an elongated grip member and a head member connected to the elongated grip member which includes a pair of fixed immovable blades. Each blade has a cutting edge. The blades are positioned in the head in opposed planar relationship to one another so that at least a portion of each respective cutting edge is in spaced opposed relationship to the cutting edge of the other blade at a distance less than the thickness of the stem of the fruit to be picked. Picking is accomplished by a thrusting motion in which the device is held in one of the laborers hands while the fruit to be picked is grasped in the other. The device is thrust at the stem of the fruit to be picked. The pair of fixed blades guides the stem into the cutting region where the stem is severed.

  • Patent number: 5386681
    Abstract: A tool for use to remove weeds, especially dandelions, which comprises an open rectangular frame having an upper rod-like member defining a handle and a lower rod-like member of a length sufficient to receive the foot of an operator. This open rectangular frame gives room not only to the foot of the operator, but also to his or her knee, thereby making the tool much easier to use. The tool also comprises a tapered extraction tube externally secured to a lower lateral side of the frame. This particular positioning of the extraction tube is of particular importance, since, thanks to its eccentric position, a rotational force may be applied to it by both the hand and foot of the operator which holds the frame, respectively. Thanks to its structure, the taperated extraction tube is also self-cleaning, as it empties automatically when another plug of soil or earth containing a weed to be extracted is inserted therein.
