         10 . The adaptor of  claim 9 , wherein the proximal and distal eyed flanges angularly extend the table between 30° and 40° from the “U” bracket's proximal and distal legs. 
     
     
         11 . A mower blade sharpening assembly comprising:
 a. An angle grinder having a neck and a rotating grinding wheel;   b. A “U” bracket having an upper web, and having proximal and distal legs fixedly attached to and extending downwardly from proximal and distal ends of the web;   c. An annular clamp adapted for engaging the angle grinder's neck and for securing said neck at a rearward side of the web, and for securing the rotating grinding wheel beneath the web;   d. A table spanning between the “U” bracket's proximal and distal legs, the table underlying the grinding wheel; and   e. Means for mounting the table upon the “U” bracket, said means forwardly extending the table from the “U” bracket's proximal and distal legs.   
     
     
         12 . The mower blade sharpening assembly of  claim 11 , wherein the annular clamp comprises an over-center latch and grinder neck encircling member combination, said combination's grinder neck encircling member engaging the grinder's neck. 
     
     
         13 . The mower blade sharpening assembly of  claim 12 , wherein the annular clamp's over-center latch is adapted for tightening the grinder neck encircling member about the angle grinder's neck and for anchoring the angle grinder at the rearward side of the “U” bracket's web. 
     
     
         14 . The mower blade sharpening assembly of  claim 13 , wherein the means for mounting the table forms a “V” cleft between upper surface of the table and a lower surface of the grinding wheel. 
     
     
         15 . The mower blade sharpening assembly of  claim 14 , wherein the means for mounting the table upon the “U” bracket further comprise proximal and distal eyed flange and travel slot combinations, said combinations'travel slots respectively opening at the “U” bracket's proximal and distal legs. 
     
     
         16 . The mower blade sharpening assembly of  claim 15 , further comprising proximal and distal feet respectively fixed attached to and extending rearwardly from lower ends of the “U” bracket's proximal and distal legs.
