gophers

I'm a little stuck... Click here to teach me more about this clue!

'burrowers' is the definition.
I can't tell whether this definition defines the answer.

'go quietly with hers' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'with' means one lot of letters go next to another.
'go'+'p'+'hers'='GOPHERS'

Can you help me to learn more?

(Other definitions for gophers that I've seen before include "Computer browsers" , "waffles" , "Creatures" .)

I've seen this clue in the Sydney Morning Herald.
