Question: In what town with a population less than 600 could one have found the attraction, World's Largest Farm Tractor, in 1998?

Context paragraphs:
Hiboy: A Hiboy is a specialized, high-clearance type of farm tractor designed to operate in high crops without damaging them.  The largest producer of hiboys is Hagie Manufacturing Company of Clarion, Iowa, United States.  The most common uses of hiboys are for detasseling, spraying herbicides, and applying glyphosate directly to weeds growing above crop height with a wick or wiper.

Juanito Apinani: Juanito Apinani (1827-1850) was a Catalan bullfighter.  He was born in Barcelona, Spain in 1827.  He was the son of Roberto Apinani and Anita Rodriguez Reginalda Apinani.  As a boy, Juanito admired the matadors and dreamed of traveling to Madrid to become one.  In 1840, he had his literal 'lucky break'.  Some men from Madrid had come to his father's farm to inspect bulls for the bullfights.  Juanito, who had been tending to the cows, noticed that one of the bulls was getting agitated.  As it charged the inspectors and his father, Juanito used his rake to vault onto the raging bull's back.  He was thrown off of the crazed animal into a tree and fractured his wrist, but the bull was diverted and the inspectors thought that his display of untrained skill could one day make him a successful matador.  By 1842, Juanito was an emerging star.  In just two years he had graduated from the training of Alexandro Anipanuevo, an ex-matador who was considered one of the best teachers in Madrid.  In another year's time Juanito was a professional matador and one of the many celebrated stars of Spain.

Malkotsis: Malkotsis is the trade name for "Technica S. Malkotsis A.E.", which has historically been the most important Greek engine manufacturer, surpassing several engine (mostly diesel and semi-diesel) manufacturers that flourished in Greece in the 1920s and (mostly) 1930s, like "Dimadis-Kanakis" in Volos, "Peteinaris" in Kalamata, "Sideris", "BIO", and others in Athens, etc.  Located in Piraeus, before World War II "Malkotsis" produced various types of industrial machinery.  After the war it produced industrial machinery for several Greek companies, but it progressively focused almost entirely on diesel engines, soon becoming the largest company in its field.  "Malkotsis" engines found use in a variety of industrial applications, while its boat engine models became legendary for their reliability.  A series of electric motors was produced as well.  Its "EM" Diesel series (designed in collaboration with a British consulting firm) included engines specifically designed for powering of vehicles and was employed in "Malkotsis's" own farm tractor models ("Malkotsis EM-2" and "EM-4") introduced in 1959.  The tractors were produced for only a few years, due to lack of funding and other problems related to a complete lack of state support.  The company faced financial problems later, due to competition from cheaper imports, and was acquired in 1991 by Drakos-Polemis A.E., a pump manufacturing company which used all "Malkotsis" infrastructure for its production purposes.

Bitter taste evolution: The evolution of bitter taste receptors has been one of the most dynamic evolutionary adaptations to arise in multiple species.  This phenomenon has been widely studied in the field of evolutionary biology because of its role in the identification of toxins often found on the leaves of inedible plants.  A palate more sensitive to these bitter tastes would, theoretically, have an advantage over members of the population less sensitive to these poisonous substances because they would be much less likely to ingest toxic plants.  Bitter-taste genes have been found in a variety of species, and the same genes have been well characterized in several common laboratory animals such as primates and mice, as well as in humans.  The primary gene responsible for encoding this ability in humans is the "TAS2R" gene family which contains 25 functional loci as well as 11 pseudogenes.  The development of this gene has been well characterized, with proof that the ability evolved before the human migration out of Africa.  The gene continues to evolve, for better or for worse, in the present day.

Paddle tire: Paddle tires are mainly used on off road vehicles, specifically designed for use in sand and mud.  They consist of a smooth tire core which has a series of large rubber cups (or paddles) attached to it.  The volume inside of a paddle is much larger than the void of a knobby tire, so it is unlikely to clog up with sand/mud.  A street legal mud tire is a more or less normal tire, but with extra large gaps or "voids" between each tread block (called "lugs") to allow centrifugal force to "self-clean" or fling the mud out of the gap.  Smaller gaps trap the mud in between the tire lugs, which turns the tire into something resembling a "slick" with no tread at all, which will have no traction in mud.  A paddle tire is an even more extreme version of this, optimized for mud or sand.  The paddle provides superior traction in the sand, in part, because the paddles dig into the sand and push off from the buried sand, not just the surface, and in mud, the gigantic "voids" give no place for mud to stick.  They work something like a paddle wheel on a paddle-steamer.  Street legal mud tires are a compromise between large voids and a smooth rolling shape for on-road use.  The more "extreme" a mud tire (such as a "Super Swamper") is, the harsher and louder it is on a hard surface.  A "tractor tire" on a farm tractor is a somewhat more mild version of a paddle tire, only the voids are smaller to allow for limited use on hard surfaces, and the "lugs" are angled to give lateral traction.  A paddle tire is so optimized for mud that the shape is of no use on anything other than a soft surface, since the vibration and lack of control of the tire would render a vehicle almost unusable.  One other way the paddle tire is a specialized-application-only is that it gives only forward/rearward traction.  This means that it is used on a wheel that drives a vehicle to push it forward, but gives little "lateral" (side-to-side) traction.  For that reason, the tires of the vehicle that steer it are generally more "normal" tires, since a paddle tire on a steering wheel will just slide sideways rather than pulling the vehicle with it.  So many 4WD vehicles will use paddle tires only on the rear, although the front wheels are powered as well.  On a 2WD or a motorbike, the rear wheel is the only drive wheel, and so putting a paddle tire on the front wheels is useless or worse, since steering performance will be negatively impacted.

John Deere 4010: The John Deere 4010 was an American farm tractor in production by the John Deere Company from 1960 to 1963.  The 4010 was the primary attraction of the new “10” series known as the “New Generation” or “New Generation of Power” which consisted of four and six-cylinder tractors first introduced in 1959 to replace the two-cylinder tractors which led to the great success of John Deere as a tractor manufacturer until that time.  The "10" series tractors were introduced to John Deere dealers in dramatic fashion on August 30, 1960 when dealers from around the world were invited to Dallas, Texas where the entire new series was debuted at the Dallas Memorial Auditorium.

Big Bud 747: The Big Bud 747 or 16V-747 Big Bud is a large, custom-made farm tractor built in Havre, Montana in 1977.  It is billed by the owners and exhibitors as the "World's Largest Farm Tractor".  It is about twice the size of many of the largest production tractors in the world, depending on parameter.

Spica-class torpedo boat: The "Spica" class were a class of torpedo boats of the Regia Marina (Royal Italian Navy) during World War II.  These ships were built as a result of a clause in the Washington Naval Treaty, which stated that ships with a tonnage of less than 600 could be built in unlimited numbers.  Thirty-two ships were built between 1934 and 1937, thirty of which entered service with Italy and two which were transferred to the Swedish Navy in 1940.  Although commonly referred to as torpedo boats, the "Spica" class were similar in design to destroyer escorts (their design was influenced by the "Maestrale"-class destroyer then in development) and were intended for anti-submarine duties, although they often had to fight aircraft and surface forces as well.  The two units in Swedish service were classed as destroyers until 1953, when re-classified as corvettes; twenty-three vessels were lost during World War II.

Big Sandy, Montana: Big Sandy is a town in Chouteau County, Montana, United States.  The population was 598 at the 2010 census.  Big Sandy, Montana, is where the Big Bud 747, the largest farm tractor in the world, was located from 1997 until 2009.  The Lewis and Clark Trail, following U.S. Route 87, goes through Big Sandy and in 2011 the town was named in a list of "Most Livable Small Towns" by Montana Outdoors magazine.

Reeves &amp; Co.: Reeves & Co. was an American farm tractor builder for thirty years, based in Columbus, Indiana.  It built some of the largest steam traction engines used in North America.
