Yell, losing head, producing blade (3)
I believe the answer is:
oar
'blade' is the definition.
(blade is the word for oar in competitive rowing)
'yell losing head' is the wordplay.
'yell' becomes 'roar' (roar is a kind of yell).
'losing head' means to remove the first letter.
'roar' with its first letter taken away is 'OAR'.
'producing' is the link.
(Other definitions for oar that I've seen before include "Boat propellant" , "Sportsman" , "spoon?" , "Sweep" , "Rowing boat operator" .)
