Trucks & Heavy Equipment | 18 January 20176 Unique and Rare Tractors Share article facebook twitter google pinterest Over the many years of farming there have been many different types of tractors produced.They came in all shapes and sizes to better perform the tasks each individual farmer might need. Like anything, some models were a huge success, while others weren’t as popular. Here are six rare tractors from The Tractor Factor. Senior Tractor Manufactured by the Moline Plow Company, the D was built from 1918 to 1923. It rated 9 horsepower on the drawbar and 18 on the belt pulley and was actually a two-wheel machine that required a sulky, or a trailed implement which provided the back wheels and a seat for the driver. The Universal was probably the first attempt by any manufacturer to make an all-purpose tractor. Some versions had water tanks in each wheel for added weight; others simply had cast cement in the wheels. The Universal had a Remy electric governor/ generator combination and a self-starter. Steering was mechanical by articulation. The engine was a four-cylinder L-head, vertical inline type with 192 cid. It only had a single forward gear and reverse. Top speed was 4 mph. The Universal weighed in at about 3,600 pounds with ballast. The Luminaries 1924 Farmall Regular. The first Farmalls are especially collectable because not many survived from their production period from 1924 to 1931. They can be readily identified by their open steering gear on the nose and by a tall air intake pipe, generally with a mesh balloon-type air cleaner. Distinctive Horsepower The tractor pictured is typical of the original 1940 O-6 orchard version of the W-6. These tractors featured sweeping and pointed fenders covering the rear wheels and a tapered shield to offer the operator a measure of protection from overhanging limbs. Air cleaner intakes were also shielded, and the exhaust came out underneath the machine. The headlights were under the grille. Rubber tires were standard equipment. Electric starting was an option on the spark-ignition versions. The O-6 weighed about 4,700 pounds. An OS-6 version did not have the rear-wheel coverings. The Little Guys The Cat Ten is the smallest Caterpillar ever built, and there were only about 5,000 of them made. The Ten weighed in at less than 5,000 pounds, which makes it easily hauled behind a ¾-ton pickup truck. There were high-clearance and wide-track models, as well as versions with electrical systems and rear belt pulleys. Unique among Caterpillars, along with its sibling, the Cat Fifteen, is the use of an L-head engine; all others have overhead valves. Fuel for the Ten was gasoline Not so Many Made The 70 made its debut a little later than its stablemates, the 50 and 60, and it shared their features and styling. It was the successor to the great G but was available in both standard-tread and row-crop configurations. It was also available in a variety of fuel choices besides the All-Fuel (distillate) option of the G. The 70’s power beat that of the G’s by almost 20 percent, even more for the fuel options other than distillate. The 70 was only made from 1953 to 1956, so total production of all types was a meager 44,000-some units. Cream of the Crop The “Holy Grail” of tractor collecting, the UDLX is one of the most sought-after tractors of all time. The best estimates are that 150 were made between 1938 and 1941. Very few were delivered to farmers, who worked them in their fields by day and then drove them to town in the evening. Most were driven by custom threshermen able to scoot between jobs towing the thresher at 40 mph. Stories recount Minneapolis-Moline salesmen driving Comfortractors to visit dealerships; that, however, seems to have been rare indeed. The UDLX (or U-Deluxe) Comfortractor was a version of the M-M U Series tractors. The UDLX featured items like a shift-on-the-fly five-speed transmission, tip-out windshields, windshield wipers, high- and low-beam headlights, taillights, heater, speedometer, and even a cigar lighter. There was somewhat cramped seating for three. Buy from an Online Retailer US: UK: With tractor historian Robert N.
