  • Patent number: 9648799
    Abstract: A tillage implement has a main frame provided with ground-engaging wheels that support the main frame at a selected height above the ground. Tillage shanks may be provided on the main frame and, if so, have their depth of penetration into the ground determined by the selected height of the main frame. Gangs of freely rotatable circular blades are carried on the main frame for both fore-and-aft angle adjustment relative to the main frame about respective upright pivot axes and up-and-down depth adjustment relative to the main frame about respective horizontal pivot axes. Such angle and/or depth adjustments can be carried out on-the-go from the tractor seat and without raising or lowering the main frame such that if tillage shanks are provided on the main frame, the working depth of the tillage shanks can remain unchanged as the gangs are adjusted.

  • Patent number: 5632342
    Abstract: A lawn spreader composed of a cylindrical drum mounted to a user-operable handle assembly. Along the surface of a drum are a plurality of spaced-apart spike arrays with a plurality of aperture arrays interposed therebetween. A door at one end of the drum allows for deposit of granular materials, such as grass seed, within the drum. A paddle array within the drum is rotatable therein so as to open or close selected apertures of the aperture arrays. Upon drum rotation, as urged by the user on the handle assembly, the spikes first indent the earth with the grass seed then falling through the open apertures and into and between the resulting indentations in the earthen surface therebetween. The smooth surface of the drum then tamps the deposited seeds into the earthen surface. The spikes are preferably releasably attached to the cylindrical drum so that various types of spikes can be used.

  • Patent number: 5020602
    Abstract: An aerator for lawns and the like has spiders formed of four identically formed members. Each member has a tine on each end, so four members provide eight tines for the spider. The members are relatively narrow, and filler members at each side of the tine members provide stability to the spider. The spiders are carried by a frame, and the frame carries a weight-receiving tray for carrying weight to assure penetration of the tines. Springs carry the tray on the frame so the springs will absorb the energy if the tines engage an impenetrable object.
