Rows and bellows, losing head (4)
I believe the answer is:
oars
'rows' is the definition.
(I've seen this before)
'bellows losing head' is the wordplay.
'bellows' becomes 'roars' ('roar' can be a synonym of 'bellow').
'losing head' means to remove the first letter.
'roars' with its first letter taken away is 'OARS'.
'and' is the link.
(Other definitions for oars that I've seen before include "Busy bodies usually stick them in, also used in rowing" , "Propellers for small boat" , "Rowing blades" , "Implements of propulsion on water" , "Soar with propellors" .)
