Overview
The Farmall 350 is a row-crop tractor manufactured by International Harvester in Rock Island, Illinois, between 1956 and 1958. It was offered with gasoline, diesel, and LP gas engine configurations and featured an optional Torque Amplifier transmission providing up to 10 forward speeds. The model is equipped with an independent 540 RPM rear PTO and was tested with a maximum belt horsepower reaching 39.34.
Ideal Applications
Multi-Fuel Engine Availability:
This model was produced with three distinct four-cylinder engine options: a 3.2L Continental diesel, a 2.9L International Harvester gasoline, and a 2.9L International Harvester LP gas unit.
Torque Amplifier Transmission:
The transmission system includes a Torque Amplifier that allows for clutchless shift-on-the-move between direct drive and a reduced ground speed setting to increase available torque.
Tested Drawbar Performance:
According to Nebraska Tractor Tests, the 350 achieved a maximum drawbar pull of 6,039 lbs in the diesel configuration and up to 6,457 lbs in the gasoline configuration.
