Home crops — limited space for horses (8)

'horses' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'home crops limited space' is the wordplay.
'home' becomes 'pad' (pad can mean someone's home).
'crops' becomes 'docks' (both can mean to cut or trim).
'limited' means to remove the last letter (a limited or incomplete form of the word).
'space' becomes 's' (this could be a standard abbreviation I've not previously seen).
'docks' with its last letter taken away is 'dock'.
'pad'+'dock'+'s'='PADDOCKS'

'for' acts as a link.
