Last Updated: July 2024

Overview

The Minneapolis-Moline G900 is a large tractor that was available with a range of engines including a 7.4L 6-cylinder diesel, a 7.0L 6-cylinder LP gas engine, and a 7.0L 6-cylinder gasoline engine. There is a discrepancy in engine displacement and bore size, with two sets of figures provided, and it's important to look at the engine serial number or additional documentation to determine the correct specifications of the engine. The G900 features a partial power shift transmission known as Ampli-Torc providing 10 forward and 2 reverse gears. The tractor has a substantial operating weight of 10,300 pounds and dimensions that contribute to its stability and presence on the field. It was designed primarily for agricultural tasks and could cater to various workload demands with its robust build and power setup. The operational data and features like the open operator station and the open center hydraulic system underline the tractor's suitability for a range of tasks in various agricultural enterprises.
