Cover a tax mix-up with machine (9)

I believe the answer is:

excavator

'machine' is the definition.
(excavator is a kind of machine)

'cover a tax mix-up' is the wordplay.
'mix-up' is an anagram indicator.
'cover'+'a'+'tax'='coveratax'
'coveratax' anagrammed gives 'EXCAVATOR'.

'with' acts as a link.

(Another definition for excavator that I've seen is " Powered machine for digging earth".)

I've seen this clue in The Hindu.
