<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">harvesting machine</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for reaper that I've seen before include "Wordsworth's was Solitary" , "Farmworker" , "One harvesting crop" , "One who cuts grain as harvest" , "One gathers" .)
