Plow part (5)
I believe the answer is:
blade
'plow part' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for blade that I've seen before include "Young chap, dashing" , "See 24 Across" , "Cutting edge" , "Cutting part of grass?" , "Flat part of an oar" .)
