Man who chops down trees? (6)

I believe the answer is:

feller

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

'man' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for feller that I've seen before include "Bloke - lumberjack" , "employed in forestry" , "the cause of planes crashing?" , "Chap informally" , "Man casually" .)

I've seen this clue in The Sun.
