Minneapolis-Moline M-670

Last Updated: June 2024

Overview

The Minneapolis-Moline M-670 is a utilitarian tractor that was designed to meet the demands of mid-sized farming operations. The tractor is equipped with a large-bore, 4-cylinder engine available in gasoline, diesel, or LP gas configurations, indicative of its versatility and ability to adapt to various fuel types available on a farm. The significant engine displacement of 336 cubic inches (5.5L), supported by a modest 12-volt electric starter system, ensures reliable performance. The tractor's engine operates at a rated speed of 1600 RPM. While specific power output is not stated, the provided operating speeds and displacement suggest a capable power delivery for daily tasks. Its two-wheel-drive chassis and open operator station point to a design that prioritizes simplicity and ease of maintenance. Equipped with an open-center hydraulic system and a category II three-point hitch, the M-670 was likely capable of handling a broad range of implements and attachments. Front and rear tire specifications emphasize its agricultural focus, and the option for Ampli-Torc power shift transmission provides flexibility in handling varied terrain and tasks. The tractor's weight varies with the fuel type: 6350 lbs for gas, 6550 lbs for LP gas, and 6500 lbs for diesel.
