Abstract
In a tillage implement for being towed by an agricultural tractor across ground to be towed and having a main frame supporting a plurality of tillage units thereon in which each tillage unit includes a disc supporting arm mounted on the main frame, disc mounting assemblies support respective tillage discs on the disc supporting arms. Each assembly includes a mounting body forming a socket therein and a shaft partly received within the socket so as to support a tillage disc on a hub rotatable on a portion of the shaft protruding from the mounting body. The shaft includes a tapered shaft section received within a tapered socket section in the socket of the mounting body to securely and releasably mount the shaft relative to the mounting body.

A disc mounting assembly for mounting a tillage disc on a tillage implement having a main frame supporting a plurality of tillage units thereon in which each tillage unit includes a disc supporting arm mounted on the main frame, the disc mounting assembly comprising:
- a shaft extending longitudinally between a first end and an opposing second end in which the second end of the shaft is arranged to support the tillage disc rotatably thereon;
- and
- a mounting body arranged to be supported on a respective one of the disc supporting arms of the tillage implement, the mounting body including a socket formed therein in which the socket receives the first end of the shaft mounted therein;
- wherein the shaft includes a tapered shaft section adjacent the first end of the shaft in which the tapered shaft section is tapered to be reduced in diameter towards the first end of the shaft;
- and
- wherein the socket includes a tapered socket section receiving the tapered shaft section matingly therein.
A tillage implement comprising:
- a main frame arranged to be displaced across ground in a forward working direction;
- a plurality of tillage units supported on the main frame, each tillage unit including a disc supporting arm mounted on the main frame to extend downwardly and rearward to a trailing end of the disc supporting arm;
- a disc mounting assembly supporting a tillage disc on the trailing end of each disc supporting arm, the disc mounting assembly comprising:
- a shaft extending longitudinally between a first end and an opposing second end in which the second end of the shaft supports the tillage disc rotatably thereon;
- and
- a mounting body supported on the disc supporting arm, the mounting body including a socket formed therein in which the socket receives the first end of the shaft mounted therein;
- wherein the shaft includes a tapered shaft section adjacent the first end of the shaft in which the tapered shaft section is tapered to be reduced in diameter towards the first end of the shaft;
- and
- wherein the socket includes a tapered socket section receiving the tapered shaft section matingly therein.
