Farming would never be easy if the agricultural and farm tractors today stayed in the drawing boards. Transferring heavy sacks of fertilizers, grains, and other farming equipment made the workload light for farmers when the tracked and wheeled agricultural tractors were introduced. These tractors were also designed to have a variety of attachments for sowing, plowing, and planting. Agricultural tractor dimensions vary in order to be able to carry these additional farming technologies.
Manufacturers of agricultural tractors have considered the importance of different farming attachments that they developed a wide range of tractor choices. The New Holland Agriculture of Pennsylvania, the AGCO Corporation of New York, and John Deere and Company of Illinois continue to design and manufacture a series of models with different agricultural tractor dimensions.
New Holland has developed six models for the T9 Series 4WD – TIER4A Tractors. Each articulated tractor runs on engines of up to 507 horsepower. The agricultural tractor dimensions vary from one tractor to another. With 20.8 R 42 tires, tractors in the series have a maximum height range of 144.2 inches (3663 millimeters) to 148.5 inches (3772 mm.). The smallest tractor in the series has an overall length of 295 inches (7493 millimeters), while the largest stretches to 300 inches (7615 mm.). The smallest of the six models has an outside frame width of 36.5 inches (929 mm.), while the largest has 44 inches (1116 mm.). The wheelbase for the smallest is 148 inches (3759 mm.) and 154 inches (3911 millimeters) for the largest. The maximum operating weight for the series ranges from 42,000 pounds (19051 kilograms) to 56,000 lbs. (24,494 kg.).
The Pennsylvania manufacturer also has the TK4000 Series Crawler Tractors. The agricultural tractor dimensions for this series also varies. The TK4030V, the most slim of the four models, has a width of 46.1 inches. TK4050 has a 55.5-inch width, while the low height TK4050M has an overall width of 68.9 inches. The TK4030V delivers 64 PTO horsepower while the other two models deliver 83 PTO horsepower. The maximum length for the models in the series ranges from 130 inches (3352 millimeters) to 135 inches (3431 mm.). The range of the height from the wheel to the top of the seat is 50.3 inches (1278 mm.) to 56.3 inches (1431 mm.). The maximum height to the top of the rollbar is from 87.0 inches (2210 millimeters) to 91.5 inches (2326 mm.).
Likewise, the AGCO has manufactured agricultural tractors under the core brands of Challenger, Fendt, Massey Ferguson and Valtra. The most interesting among the more than 100 models can be found in the Challenger MT800C Special Application series. All four tracked models in the series were designed with ultra-hard wearing polyurethane mid-wheels and full-length debris deflector. The agricultural tractor dimensions in the series are not too high for the 430 to 570 rated horsepower of the engines.
Finally, John Deere also offers tracked and wheeled tractors in its 2011 8R/8RT Models. The 8335RT Tractor is the largest of the 10 models. It has a wheelbase of 99 inches (2515 millimeters). It runs on a 335 horsepower engine. The agricultural tractor dimensions in terms of width and height are stable. The overall width from axle end to end is 134.6 inches (3420 mm.), but the width expands to 174.6 inches (4435 millimeters) with the wide axle kit installed. The command view height is 131.3 inches (3334 millimeters). The length is dependent on the attachment. With the hitch, drawbar, and front weight support (excluding front suitcase weights) the length ranges from 253.1 inches (6428.4 mm.) to 256.5 inches (6514.2 millimeters). With the hitch, drawbar, front weight support, and front suitcase weights, the length ranges from 267.5 inches (6795.4 millimeters) to 270.9 inches (6881.2 millimeters).
