Combines are massive machines, only slightly smaller than locomotives. They were used before the Great War to harvest crops. The design is comprised of the main harvester and cockpit fixed to a box frame with four long supports, each with two large wheels. The combine has a total of eight wheels and has a grain chute protruding from the side. An open-bed truck would drive alongside the combine collecting grain discarded from this chute.
- An orange intact combine can be found near Sunshine Tidings co-op.
- A dark blue destroyed combine can be found in the Glowing Sea, although it is mostly buried in ash.
The combine is not a single object but is made up of multiple objects, similar to buildings.
