Massey Ferguson 7726 Dyna 6 Diesel

Last Updated: July 2024

Overview

The Massey Ferguson 7726 Dyna 6 Diesel is a part of the 7700 series, identifiable by its advanced 6-cylinder AGCO Power AP74-4 engine, which is liquid-cooled and employs a turbocharger with an air-to-air intercooler system. Operating with a rated power of 208 horsepower (maximum), this engine is designed to handle heavy-duty agricultural tasks. The tractor's emissions are managed by a combination of Tier 4 standards and selective catalytic reduction technology, ensuring compliance with environmental regulations. Transmission options include a six-speed power shift - offering 24 forward and reverse gears, or a continuously-variable transmission (CVT) for seamless transitions and infinite gear ratios, supporting versatility across operations. Notable features include a maximum torque of 722.5 lb.-ft. at 1201 rpm, a torque rise of 38.9%, and a hydraulic system capable of exerting a maximum force of 13,920 lbs at the hitch points. Its high-capacity hydraulics with a flow of 29.1 gallons per minute can handle demanding implements and attachments. From the year of manufacture starting in 2015, the Massey Ferguson 7726 Dyna 6 Diesel continues to be an integral asset for agricultural producers who require reliability and power.
