Introduction
Allis Chalmers 190 Row-Crop Tractor
The Allis Chalmers 190 is a row-crop tractor produced in West Allis, Wisconsin, between 1964 and 1972. Positioned as a reliable workhorse for agricultural operations, this model was built to offer power and operational flexibility during a period of significant technical evolution in farm machinery.
Engine and Performance
The tractor is powered by a liquid-cooled, 6-cylinder engine with a displacement of 301 cubic inches (4.9 liters). It utilizes a direct injection fuel system and operates at a rated engine speed of 2200 RPM. The engine features a 16.25:1 compression ratio and is designed for consistent performance in demanding field conditions.
Transmission and Drive
The 190 features the Power Director transmission, offering 8 forward and 2 reverse gears. This system includes a two-speed power shift that allows for on-the-go speed adjustments without the need to use the clutch. The Power Director lever also serves as a neutral control, which can stop the tractor while keeping the PTO engaged, a feature useful for stationary implement operation.
Hydraulics and PTO
The tractor is equipped with an open-center hydraulic system providing a pump flow of 12 gallons per minute (45.4 lpm) at 2000 psi. The rear PTO is a live, continuous system that can be operated at 540 RPM or 1000 RPM, providing versatility for various power-driven attachments.
Mechanical and Operator Environment
Built on a 105-inch wheelbase, the tractor features power steering and band-actuated disc brakes for improved handling. The operator station is an open-platform design, though factory-installed cabs with optional heating and air conditioning became available starting in 1965.
Conclusion
With 4,726 units produced, the Allis Chalmers 190 serves as a robust utility tractor suited for row-crop applications requiring reliable power, adjustable tread widths, and the operational advantages of the Power Director transmission system.
