Introduction
Minneapolis-Moline 2 Star Crawler Tractor
The Minneapolis-Moline 2 Star is an agricultural crawler tractor produced in 1958 in Minneapolis, Minnesota, USA. Part of the MoTrac series, this machine was designed for specialized field operations requiring high traction and stability.
Engine and Performance
The tractor is powered by a Minneapolis-Moline 206K-4 gasoline engine, a liquid-cooled 4-cylinder unit with a displacement of 3.4 liters. It delivers a rated power output of 57 hp (42.5 kW) at 1900 engine RPM. The engine features a bore/stroke ratio of 92 mm by 127 mm and a compression ratio of 7.3:1.
Transmission and Drive
The 2 Star utilizes a crawler drive system with 12-inch wide tracks, ensuring optimal weight distribution and traction on soft or uneven terrain. The transmission is a power shuttle type, providing 5 forward and 5 reverse gears, which allows for efficient directional changes during operation.
Hydraulics and PTO
The hydraulic system is of the open-center type, featuring a pump flow capacity of 25 gpm (94.6 lpm), which supports the operation of various mounted implements. The rear power take-off (PTO) operates at 540 RPM, achieved when the engine is running at 1845 RPM.
Dimensions and Build
With a total weight of 9130 lbs (4141 kg), the tractor provides the necessary mass for heavy-duty pulling tasks. It features an open operator station design, typical of its era, and was produced in a limited run of 51 units.
Conclusion
The Minneapolis-Moline 2 Star is a specialized agricultural crawler tractor suited for operations where conventional wheeled tractors might lack sufficient traction. Its combination of a 57 hp gasoline engine and a power shuttle transmission makes it a distinct piece of agricultural equipment from the late 1950s.
