A bit of a warning on AreaOnAreaOverlayer. If the Farm polygons happen to also overlay each other then they will possibly not get the attributes of Land Classifications since Attribute Merging is done on first come-first serve basis in the Transformer depending on the order that the Features enter the single Input Port and one Farm may just merge the attributes from another overlaying Farm rather than a Land Classification. I find to use it when feeding it multiple layers that I need to tightly control it with the Group By set to a group identifier that only overlays one feature from the layer I want to update, with a corresponding group identifier that corresponds to spatially related features from the layer I want to get the values from.
An alternative is to use Clipper with Merge Attributes enabled, with the Farms as the Clippee and the Land Classifications as the Clipper. It is a little bit slower than AreaOnAreaOverlayer, but at least all the Output features are the Farms Polygons only (AreaOnAreaOverlayer will output any sections of the Land Classifications that don't overlay a Farm and these will need to be filtered out). Another advantage is that if there are farms that overlap each other in any place, they won't clip each other.
