JOTUN Heavy Industries

Jotun Heavy Industries is a Human company based on Mars. They design and manufacture farming and other agriculture equipment and are specialized in the construction of semi-autonomous farm machinery.

There are at least five series of JOTUNs Farming Equipment and at least one prototype model.

Series 2
This series is out of date and mainly used by smaller farmers on Harvest.

Series 4
Series 4 are larger machines that can host a part of an A.I. Mack used machines of this series to survive Harvest as long as possible. The series 4 Gondolas collect crops from the sides of the machines. Johnson and Byrne used one of these to provide a distraction while they snuck up on the recruits in Halo: Contact Harvest.

Series 5
Series 5 are larger machines that can host a part of an A.I. Mack used machines of this series to protect Harvest for as long as possible. The series 5 Gondolas collect crops from the rear of the machine. It is powered by a three thousand horsepower ethanol-electric engine.

Multi-tasking machines
Although their official name is unknown, Johnson saw these in the Harvest's capital city of Utgard. They are a series of JOTUNs that are capable of doing a large variety of different tasks.

Prototypes
One of the prototypes was on a Human freighter, This End Up, commanded by Henry "Hank" Gibson, who was killed in the resulting fight with the Covenant. When the Covenant attacked the vessel, the Huragok Lighter Than Some saw the prototype and built four vehicles based on it that would be later known as the Type-25 Rapid Assault Vehicle, which is also later known as the "Brute Chopper" later in the Human-Covenant War.

The machine Gibson was carrying was a massive machine designed to till wide swaths of earth. It has six massive wheels and a large beam with spikes on the front to carry around the earth.

Cropdusters
JOTUN crop dusters are used to spray fertilizers and fungicides on a variety of crops.

Oliphant
After being ordered by Sadie Endesha to commandeer city transportation to move an 800 pound man named Jonas, New Mombasa's Superintendent pulled schematics out of its database depicting an Olifant (a variant of the UNSC's standard Elephant HRV) labeled with a Jotun insignia, indicating that Jotun Heavy Industries may be responsible for producing both Olifant garbage trucks and the larger Elephants as well.

Others
There is little or nothing known about JOTUN's Series 1 and 3 machines.
