Introduction
Leader 15-25 Standard-Tread Tractor
The Leader 15-25 is a standard-tread agricultural tractor produced in 1917 by the Leader division of Dayton-Dick in Quincy, Illinois, USA. This machine represents early 20th-century tractor design, focusing on mechanical simplicity and utility for field operations.
Engine and Powertrain
The tractor is powered by a 4-cylinder, liquid-cooled engine with a displacement of 302 cubic inches (4.9 liters). It utilizes a Kingston carburetor and operates on kerosene, reaching a rated speed of 750 RPM. The engine is started via a hand crank. It delivers 15 hp (11.2 kW) at the drawbar and 25 hp (18.6 kW) via the belt, providing sufficient output for pulling 3 to 4 fourteen-inch plows.
Transmission and Chassis
The drivetrain consists of a manual gear transmission offering two forward speeds and two reverse speeds. It is configured as a two-wheel-drive machine with manual steering. The tractor features an open operator station and rides on 48x12 steel rear wheels, contributing to its overall weight of 5,000 lbs (2,268 kg).
Physical Dimensions
The machine measures 134 inches (340 cm) in length, with both width and height standing at 60 inches (152 cm). These dimensions characterize its compact profile for the era, designed for stability during heavy traction work.
Conclusion
The Leader 15-25 is a representative example of early American agricultural engineering. Its design, centered around a kerosene-fueled 4-cylinder engine and a simple manual transmission, suited the requirements of farms seeking mechanical assistance for plowing and belt-driven stationary tasks in the late 1910s.
