ARTICULATED TRACTOR WITH SPLIT TRANSMISSION DRIVE Abstract of the Disclosure An articulated four-wheel drive tractor has front and rear frame structures joined by vertical pivots and supported by front and rear drive axle assemblies. The tractor has a split, speed change transmission with a first section supported on the front frame structure and a second section supported on the rear frame structure. The first transmission section is driven by an engine mounted above the front axle structure and its output is trans- ferred to the second transmission section through an upper drive- shaft which crosses the axis of articulation and drives a gear train on the rear frame structure forwardly of the second trans- mission section. The second transmission section output shaft is connected directly to the rear axle assembly and is connected to the front axle assembly through a second driveshaft which crosses the axis of articulation below the upper driveshaft. A live PTO is connected to the engine output shaft in front of the first transmission section and includes a PTO driveshaft which crosses the axis of articulation between the first and second driveshafts. Each of the three driveshafts crossing the axis of articulation includes a pair of universal joints equally spaced to the front and rear of the pivot axis.
