Introduction
Advance-Rumely OilPull Z 40/60 Tractor
The Advance-Rumely OilPull Z 40/60 is a vintage heavy-duty tractor introduced in 1929. Manufactured by Advance-Rumely, this machine represents a significant era of agricultural engineering, characterized by large-displacement kerosene engines and robust frame construction designed for extensive field work.
Engine and Performance
The tractor is powered by a 2-cylinder kerosene engine with a massive displacement of 22.9 liters (1400 ci). The engine operates at a rated speed of 470 RPM, with a bore and stroke measuring 229 x 279 mm. This configuration provides a claimed drawbar power of 40 hp (29.8 kW) and a belt power of 70 hp (52.2 kW), allowing the machine to drive stationary equipment or pull heavy implements such as a 12-bottom 14-inch plow set.
Transmission and Dimensions
The drivetrain features a 3-speed forward transmission to manage power delivery. Given its primary application in heavy traction, the tractor is built with a substantial operating weight of 18,000 lbs (8,164 kg), which provides the necessary ballast for high-torque operations in agricultural fields.
Production and Heritage
Production of the OilPull Z 40/60 was limited, with a total of 215 units manufactured. At the time of its release in 1929, the tractor had an original list price of $3,500. Due to its limited production numbers and historical role in early-20th-century farming, it remains a notable machine for agricultural historians and collectors.
Conclusion
The Advance-Rumely OilPull Z 40/60 is a heavy-duty tractor engineered for high-load agricultural tasks. Its combination of high-displacement kerosene power and significant mass made it a capable tool for large-scale plowing and stationary belt-driven operations during the late 1920s.
