Massey Ferguson 3680 Tractor
The
Massey Ferguson 3680 row crop tractor was manufactured between 1988 and 1991.
The Massey Ferguson 3680 tractor is equipped with a 452 cubic inches (7.4 L)
Valmet 612 DS four-stroke six-cylinder turbocharged intercooled diesel engine.
The engine has a cylinder bore of 4.25" (108 mm), piston stroke of 5.28" (134
mm), rated power of 180 hp (134.2 kW), and maximum torque of 670 Nm (495 lb-ft)
at 1400 rpm.
The speedshift transmission consists of a hydraulic wet clutch and
two-speed powershift gearbox with 16 forward and 16 reverse gears. Max.
forward speed - 21.8 mph (35 km/h), maximum reverse speed - 20.5 mph
(32.8 km/h). The Massey Ferguson 3680 has an open center hydraulic
system with a gear pump flow of 14.1 gal/min (53.4 l/min) and auxiliary
pump flow of 13.2 gal/min (50 l/min). The hydraulic system pressure is
175 bar (2550 psi).
The 2-wheel drive models are equipped with 14Lx16 front tires and
20.8x38 rear tires. The 16.9R28 front tires and 20.8R38 rear tires are
used for tractors with 4-wheel drive. The wheel base is 115.7" (2930 mm)
for 4x2 (2WD) models and 115.1" (2920 mm) for 4x4 (4WD) models.
