Machine possibly combined with server that almost crashed (9)
I believe the answer is:
harvester
'machine possibly combined with server that almost crashed' is the definition.
'harvester' can be an answer for 'machine' (harvester is a kind of machine). I'm not certain of the remainder of the definition.
'server that almost crashed' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'crashed' indicates an anagram.
'server'+'that'='serverthat'
'serverthat' with its final letter taken away is 'servertha'.
'servertha' is an anagram of 'HARVESTER'.
Can you help me to learn more?
(Other definitions for harvester that I've seen before include "One gathering in crops" , "may belong to farmer" , "Crop gatherer" , "Farm worker" , "Long-legged spider" .)
