6. The disc blade hanger mounting assembly of claim 5 , wherein said L-shaped plate is a casting.

7. The disc blade hanger mounting assembly of claim 5 , wherein said second wall of said L-shaped clamp includes a through-hole, said disc blade hanger includes a through-hole, said disc blade hanger further coupled to said L-shaped clamp by a bolt passing through the through hole of the disc blade hanger and the through-hole of said second wall of said L-shaped clamp and secured by a fastener.

8. A method of attaching a disc blade hanger to a frame tube of an agricultural tillage implement, the method comprising:

providing a disc blade hanger mounting assembly including:

an L-shaped clamp including a first wall and a second wall which is substantially perpendicular to said first wall; said first wall including two through-holes; said second wall including a body, a first upstanding tab, and a second upstanding tab; said body and said first upstanding tab forming a first recess; said body and said second upstanding tab forming a second recess;

a support plate with two through-holes;

a first L-shaped bolt and a second L-shaped bolt, each of said first L-shaped bolt and said second L-shaped bolt including a first leg with a first end and a second leg with a second end; and

a plurality of fasteners;

positioning said disc blade hanger mounting assembly on said frame tube, said frame tube including a rear side and a bottom side, said first wall of said L-shaped clamp being positioned adjacent said rear side of said frame tube, said second wall of said L-shaped clamp being positioned adjacent said bottom side of said frame tube, said L-shaped clamp being open toward a direction of travel, said frame tube being positioned between (a) said first upstanding tab and said second upstanding tab, and (b) said first wall;
