Can anyone explain to me how the mine factory upgrades for the harvester work? Eg - Diamond Upgrade 12267:8 (Radius Increase: 9)

I tried making them and putting them into the harvesters but when I do they just stop harvesting. Any information on these upgrades would be greatly appreciated as we are lacking a wiki page for them.
