>Since 1974, the Census of Agriculture has defined a farm as any place from which $1,000 or more of agricultural products were produced and sold, or normally would have been sold, during the census year.

That's a weird definition.

Acres of contiguous land controlled by a single owner is how people tend to use the word farm.

In reality, farmers are often equipment owners and negotiate with landowners to manage X acres.

None of this discussion is worth wile in referencing farms.

Best could be said : a farmer who has to service equipment equal to a 400 acre farm benefits by laws protecting their farm equipment.
