Overview

The Massey Ferguson 3645 is a versatile tractor, equipped to meet the demands of both utility and row-crop applications. Its two chassis variations, 4x2 two-wheel drive and 4x4 four-wheel drive MFWD, along with power steering and hydrostatic power, highlight its adaptability and enhanced maneuverability. Depending on the model variant, it offers multiple transmission options, including 8-speed SynchroShuttle, 12-speed, 24-speed and 32-speed PowerShuttle, and 16-speed and 24-speed SpeedShift, providing a wide range of speed selections for different tasks. The heart of the 3645 lies in either a 3-cylinder or a 6-cylinder diesel engine, boasting a displacement of 201 cubic inches or 365 cubic inches, respectively. Available with either an AGCO SisuDiesel 33 DT or a Perkins 1006.T turbocharged engine, these liquid-cooled systems provide rated RPMs of 2200 with power outputs of 91 hp or 145 hp. The tractor operates within Tier III emission standards and features a dual dry element air cleaner and an intake heater for improved performance under various conditions. With approximate operating weights ranging from 5071 to 7056 pounds, the Massey Ferguson 3645 presents substantial lifting capabilities with a rear hitch lift capacity of 5515 pounds at 24 inches behind lift points. The tractor's dimensions accommodate its heavy-duty tasks with lengths up to 185 inches, width reaching 76 inches, and an impressive height with the cab reaching 113.8 inches. It was produced from 1990 to 1995 as part of the 3600 Series, solidifying its place within the agricultural machinery timeline as a durable and reliable option for farmers.
