This attachment is used to take any materials that are gathered with a mining drill out of another person's inventory and goes directly into the striders, it also comes with two saddlebags that give it 60% more weight, if you are going for a harvesting strider then get the strider with two saddlebags on its sides and the resource attractor rig that looks like a drill on the front of its head, incredible for gathering resources as the resource attractor rig is already broken but paired with the saddlebags and the ability to harvest things with the mining drill at 60% less weight is something you just can't pass up
