This Mod was made to Bring the old ore harvester from Red Alert to Factorio.
It comes with two harvesters and a refinery, the harvester will automatically mine ores it is sitting on top of, and will unload when it nears the refinery. As of right now, it must be manually driven but makes up for this with a relatively high rate of mining.
