AGCO S.A. RT165A

Last Updated: August 2024

Overview

The AGCO RT165A (also known as Massey Ferguson 6497 Diesel) is a robust row-crop tractor with significant power output and advanced engine capabilities. It is equipped with a turbocharged intercooled SisuDiesel 74CTA engine with a vertical cylinder orientation and 24 valves. The engine has a displacement of 449.4 cubic inches, a bore of 4.252 inches, a stroke of 5.276 inches, and a compression ratio of 17.5 to 1. The rated power output is 200 hp at the base level, with a maximum of 208.9 hp observed during testing. The engine produces a maximum torque of 633.9 lb-ft at 1450 rpm. The tractor features dual transmission options: a 24-speed partial power shift and a continuously variable transmission (CVT) for infinite speed adjustments. It operates on a 4x4 MFWD 4WD chassis with power steering and multiple wet disc brakes operated by a foot pedal. The hydraulic system is a closed center pressure flow compensated (PFC) type, capable of delivering up to 30.8 GPM at minimum pressure. The three-point hitch (Category 3) can exert a maximum force of 14,545 lbs. The tractor has a wheelbase of 118 inches and an unladen weight of 17,460 lbs. Tire sizes and tread widths vary based on ballasting configurations.
