Abstract
In a rotary earth crumbler having a central shaft (1) with mounting discs (2) fast thereon and an annular series of U-shaped resilient stirrups (3), the leg portions of these stirrups are formed with an outwardly convex curved section (12) which extends into a fixing slot (11) in the mounting disc and is then locked therein by deformation of parts of the slot borders below the mid portion of the curved section, thereby narrowing said slot. The locking may easily be released when needed, viz. by bringing the slot borders back to the original shape.
