Minneapolis-Moline M-604

Last Updated: June 2024

Overview

The Minneapolis-Moline M-604 is a classic tractor model from the Minneapolis-Moline line, which became known for its versatility and durability. With an Ampli-Torc two-speed power shift transmission, operators have access to 10 forward gears and 2 reverse, providing flexibility for a wide range of tasks. The tractor is available in three fuel type configurations: gasoline, diesel, or LP gas, each having slightly different operating weights—7220 lbs, 7370 lbs, and 7420 lbs respectively. The engine, a 336 cubic inch (5.5L) four-cylinder unit, comes with an oil bath air cleaner and is rated at 1500 RPM. Though exact power output and cooling type are unknown, the rating suggests that it’s adequate for moderate to heavy farm tasks. Traction is provided by large agricultural tires, and with a wheelbase of 84.5 inches and ground clearances varying by axle and drawbar location, it is suited for a wide variety of agricultural operations. The dimensions of the M-604 (Length: 140 inches, Width: 84 inches, Height to the steering wheel: 72 inches) indicate a robust design capable of stable operation in different farm settings. Specific details on the steering system, PTO type, hydraulic system, and other features remain unspecified, reflecting the information available for this historic tractor.
