The Pioneer Tractor Junior is a standard-tread tractor that comes with a 4x2 2WD chassis setup and is steered manually. Designed with simplicity in mind, it features a 5-speed gear transmission system, with 5 forward and 1 reverse gears. The tractor is powered by a Pioneer Tractor gasoline engine, which is a 4-cylinder liquid-cooled unit with a displacement of 792 cubic inches. The cylinders have a bore and stroke of 6.00 and 7.00 inches, respectively, and the engine has a low rated RPM of 625. The tractor's large steel rear tires measure 72 inches in diameter, contributing to its stability and robustness, primarily when used for heavy-duty applications. It is a relatively large machine with a length of 157 inches, a width of 87 inches, and a height of 64 inches, and it weighs in at 11,000 pounds. The Pioneer Tractor Junior's design is consistent with the needs of its time, emphasizing durability and essential functionality. It lacks some modern features such as power steering, hydraulic systems, and sophisticated hitching systems which are not detailed in the specification provided. Despite its age, the Junior may still be found in use today, especially in settings where its simplicity and ruggedness are considered advantages.
