This owner has to scatter seed (3)
I believe the answer is:
sow
'scatter seed' is the definition.
(thesaurus)
'this owner has' is the wordplay.
'has' indicates the answer is hidden within the clue.
'SOW' is hidden within 'this owner'.
'to' is the link.
(Other definitions for sow that I've seen before include "Scatter seed; pig" , "Female bear" , "Plant seed in soil" , "Broadcast" , "Female badger" .)
