Farmer Definitions in Minden area

A question on definitions of farmers positions.

I know that colon refers to someone holding the heriditary leasehold of a
property - that is someone with the right to farm a property and the right
to pass the leasehold to sons or daughters - but the land itself is actually
owned by nobles or the church and rent (a lease) must be paid.

I understand that a Heuerling is a hired hand - someone who might also rent
part of a farm from a colon, help the colon with the large farm, and perhaps
pay rent with a portion of the crops he himself grows on his piece of rented
land.

I understand Taglohner is a day laborer, usually on a farm.

If these are correct - what is a neubauer? Sounds like a new farmer, but
that doesn't tell me much.

How does the word Vollmeier fit into this heirarchy, or is it just a more
general term for someone who farms a decent size farm?

And what is an Acker (I am told it too is a farmer) and what is a landwirt?
