Minecraft Win10 Edition: Why do not my peasant villagers harvest a field from me but only plant, does the field have to look like yours in the village?

I have no idea.

As soon as the plants should have gotten used to the field already?

Did you already wait?

It may take a while

Have been waiting about 10 Minecraft nights.

I mean there has to be a valid house nearby. The villager must view your field as a field of a village. Look at the Minecraft Wiki for what to do to relocate

Do your villagers have a home so they have the official farmer job?

Build them a house: 3x3 (bird's eye view)

Row 1: Nothing, Stone height 2, Nothing

Row 2: stone height 2, door, nothing

Row 3: Nothing, Stone height 2, Nothing

When you're done, build a roof over it.

Which block you use for stone does not matter, as long as it is not translucent!

Do this a few times and just wait.

But please explain to me again, why exactly the villager should cut something down.

This only makes sense if the 8 slots inventory of the Villager is full, otherwise he automatically collects it!
