The Agricultural Tractor


In 1964, the J. I. Case Co. introduced a four-wheel drive, eight-plow 120 horsepower agricultural tractor designed for large-acreage work and difficult traction conditions. Called the 1200 Traction King, the tractor was the largest in the Case agricultural line and first Case ag tractor with four-wheel drive.

The largest Case farm tractor previously was the 930 Comfort King, a six-plow machine.

The Traction King, being a four-wheel drive machine, was initially produced at the Case "wheeled shop" at the plant in central Racine, along with the firm's line of rubber-tired industrial loaders. Three of the loader models had four-wheel drive.

Traction King production was to eventually be moved to the Case plant in Rockford, Illinois, along with that of loader manufacturing, due to the anticipated increase in production schedules.

The then new Traction King was powered by a Case six-cylinder diesel engine. The unit was rated as capable of plowing 40 to 65 acres a day with an eight-bottom 16-inch plow and 100-150 acres with chisel plows, the company said.

The machine, which also has four-wheel steering, is suited for soils ranging from muddy or wet to heavy, grasslands and marshlands or swamps.

Independent front- and rear-wheel steering allowed conventional front-wheel steering for long runs, shallow turns and transporting, as well as coordinated four-wheel steering for close-quarters maneuverability. There is crab steering for hillside work.

The Traction Kings weighed in at 15,000 pounds and with a 100-inch wheelbase.


In 1972, Case introduced the model 2470 TRACTION KING four-wheel drive agricultural tractor.

Standard equipment included:

The parking brake is independent and mechanical, while the fully enclosed, multiple wet disc service brake is hydraulic and self-adjusting.

The Cab is on an isolated rubber mounted platform that is integral, roll-protected and with seat belts. Hand throttle. Console controls are right beside the operator's seat. Instrumentation shows alternator, fuel level, engine oil pressure, radiator temperature, tachometer with hour meter, pyrometer, transmission pressure and temperature gauges, fuel pressure, hydraulic filter gauge and brake warning light. Seat with arms and backrest, adjustable.

The power shift transmission is a 12-speed constant mesh.

Powered by a 504 cu. in. displacement, 8.25 liters, 6-cylinder, diesel turbo-charged engine. Dual  fuel tanks have 110 gallons capacity. An aspirated Stratatube air induction system with dry type final and safety elements. Muffler with aspirator and curved extension.

There is a 12-volt electrical system with 55-amp alternator. Neutral start safety switch starter.

The hydraulics have 2 remote circuits. Front wheel hydrostatic power steering, with tilting and telescoping steering column.

The tractor's fenders have steps and hand rail. There are 2 front headlamps, one rear flood and tail light and 2 cab-mounted amber flashing warning lights. SMV safety symbol and safety reflectors. Integral tool box.

Tires are 4 - 18.4-30-6 ply - R1. Wheels are adjustable tread (72" - 88").

These tractors' options include power take off shaft, 3-point hitch, and rear steering axle assembly.


New in 1973 was the model 620 Allis-Chalmers small Agricultural Tractor. Described as  maneuverable as a lawn and garden tractor. Featuring a 19 1/2 horsepower engine coupled to a Hydrostatic Drive with three speed ranges. Front PTO with electrically controlled clutch was standard equipment.Hydraulic tilt system for center-mounted attachments. Optional rear PTO and a full line of work-saving accessories.


Ads for the 1957 Case Model 310 boasted of the following features: Heaviest track frame assembly, strongest of any agricultural tractor; Rigid torque tube; More Push and Pull Power per pound of weight; 42 horsepower high compression engine; High clearance; Accessories like Angle blade, straight blade, high lift, plus all the other Case refinements.


In the 1965 Kansas Slate Fair, a 53,000-pound agricultural tractor shown by Western Tractor, Inc., of Kansas City, Mo. entered the competition for the largest single piece of equipment on display. The monstrous tractor, which rode on four earth-moving tires that retail for about $1,800 each, made its first public appearance at the fair.

Price tag on the big Western Model 21 was only slightly less than $1 a pound, at $45,000. And at even that price, it was a moving item at the Fair. Two of the big tractors were sold, one to a Spearman, Texas man who farmed 26,000 acres.

The tractor pulls with all four wheels, has coordinated steering of both front and back wheels, or crab steering, or independent front wheel steering all at the touch of a control lever.

Naturally, there's power on everything - steering, gear shift and power outlets for implements.

To most farmers, this might have been viewed as an unwieldy piece of equipment that would hardly fit in their driveway. It is designed specifically for big farming operations where there's a need to cover up to 1,000 acres a day. Two smaller models are available and might be more suitable, both in the bank account and in size, to use on the moderately large farm. They began at $18,900.

The big Western could pull up to 150 feet of one-way plow, about 90 feet of chisel or a 24-bottom moldboard plow and can cover up to 1,000 acres in a day.

The small Western tractor pulled only 12 bottoms, 32 feet of one-way plow or 36 feet of chisel.

One of the large tractors and one of the small ones were under a continuous test in Montana during that summer of 1965. Western Tractor, Inc., was a closed corporation. It's stockholders were said to be large farmers and implement dealers. The tractor had been designed specifically for agricultural use in the mid western states, although it was also adaptable to industrial uses.

Major component parts of the tractor, excluding the outer shell, were made by major implement and heavy equipment companies. The engines were standard Allis Chalmers. Repair parts were to be readily available from major dealers to insure that the Western will not be a "fence row tractor", one idle for four or five days after a breakdown while waiting for repair parts.

Specialized repair parts outlets were not considered to be necessary, since the parts are standardized and already available through most agricultural tractor implement dealers.
