Rural pile has riding gear around yard (8)
I believe the answer is:
haystack
'rural pile' is the definition.
'has riding gear around yard' is the wordplay.
'riding gear' becomes 'tack'.
'around' indicates putting letters inside.
'yard' becomes 'y'.
'has'+'tack'='hastack'
'hastack' enclosing 'y' is 'HAYSTACK'.
(Other definitions for haystack that I've seen before include "Pile of cut grass" , "Large pile of fodder" , "Pile of dried grass" , "Large mound of dried grass" , "Rick of dried grass" .)
