It guides the ploughman (6)

Ross

I believe the answer is:

tiller

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

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

'it guides' is the wordplay.
I cannot quite see how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
The remaining letters 'iller' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for tiller that I've seen before include "Bar that turns rudder in small boat" , "Steering lever" , "Shoot" , "Boat's steering bar" , "Handle for turning rudder" .)

I've seen this clue in The Globe and Mail.
