Too quick to put hay out of the way (5)
I believe the answer is:
hasty
'too quick' is the definition.
(I've seen this before)
'hay out of the way' is the wordplay.
'out of' is an insertion indicator (some letters on the outside of others).
'the way' becomes 'st' (abbreviation for street).
'hay' going around 'st' is 'HASTY'.
'to put' is the link.
(Other definitions for hasty that I've seen before include "Precipitous" , "Too hurried, careless" , "Rash; hurried" , "Impulsive" , "Too quick, impetuous" .)
