I might be back with the harvest (5)

'back with the harvest' is the definition.
I know nothing about this answer so I can't judge whether this works.

'i' is the wordplay.
I cannot quite see how this works, but
'i' could be 'me' and 'me' is present in the answer.
The remaining letters 'sse' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'might be' acts as a link.

Can you help me to learn more?
