 journaled in a vertically-adjustable beam or 

 frame mounted on draft-wheels, substantially 

 as and for the purposes specified. 



2. The rotary plowing-disks A' A', one or 

 more, consisting of the annular concavo-con- 

 vex dish-shaped or flaring working or cutting 

 blades G' G', made in sections, removably ap- 

 plied to the outer ends of radial arms or spokes,-

 Claim. 1. In a tilling implement combin- 

 ing two or more revolving cutters and a rotary 

 sifting grate or harrow, the interposition be- 

 tween them of a fixed spade composed of plow- 

 ing points projecting between said cutters and 

 uniting back of them to form a common spade 

 surface, so inclined that the earth divided by 

 the cutters shall be raised, passed rearward 

 and dropped into the furrow so made, or upon 

 pulverizing or sifting devices, substantially as 

 described and shown. 



2. In a tilling implement combining a fixed 

 spade and a rotary sifting-grate, the combina-

 tending above and below the plane of their 

 surfaces or centers a sufficient height and 

 depth to confine the upcoming earth upon 

 them, and to keep open the furrow-space be- 

 low them for the redeposit of the earth after 

 preparation by the sifting-grate, substantially
