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 considered obsolete by 2525 and mainly used by smaller farmers on Harvest.

Series 4
Series 4 are larger machines that can host a part of an AI Mack used machines of this series to survive for as long as possible after Harvest's glassing. 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 a new vehicle type based on it that would be later known as the Brute Chopper.

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 cropdusters are used to spray fertilizers and fungicides on a variety of crops.

Elephant HRVs
JOTUN also manufactures the M312 and M313 "Elephant" mobile recovery platforms, as well as the vehicle's civilian variant, the Olifant garbage truck.

Others
Almost nothing is known about JOTUN's Series 1 and 3 machines.

Trivia

 * During the First Battle of Harvest, Harvest's agricultural operations AI, Mack, transfered himself into the thousands of JOTUNs on the planet. As the Covenant glassed Harvest, Mack used the JOTUN machines to relay messages to the colony's shipping operations AI, Sif, when both of their data arrays had been destroyed. His messages were later recorded in ONI Colonial Security Estimate 2525.10.110.
 * The name JOTUN is a phrase from Norse mythology, meaning "giant", fitting with the many Norse references on Harvest.
 * Mack used JOTUN cropdusters to knock down a Spirit dropship in Utgard.
 * The Brute Chopper is based on the JOTUN farmer vehicle and was created by the Huragok Lighter Than Some as a peace gift to humanity.
 * In Halo 3: ODST, Jotun's company logo can be seen on multiple buildings in New Mombasa, suggesting that they had a branch in the city.
