One end of the sleeve 16 such as I8 is convex so as to bear against the concave portion of the adjacent disk while the opposite end I9 is concave to contact with the comple mentary curved portion of its adjacent disk. The ends of the shaft l5 are threaded as at 20 to receive the retaining nuts 2 l'.

A event it is desired to use the disks Ill with a dif square shaft for the same size of disk. By ar ranging the central opening in the disk so as to accommodate a shaft of either size, the same disk’ can be conveniently connected to a large or small size shaft and thus eliminate the necessity of providing separate disks for each size of shaft. ferent ‘size ,harrow shaft, this can conveniently be done ‘upo’nldismantling the disks from‘ the invention shown and described are merely illus washer 26 has a similar shaped central opening 21 and is held against the concave portion of the adjacent disk It! by the other nut so that when the parts are set up, the disks are maintained ?rmly in locked position on the shaft l5. ‘In the vIt; will be understood that the forms of the shaft I4 and connecting themrto the larger size 10 trative of preferred embodiments and that‘ such square shaft 28 (Fig, 16).
