Massey Ferguson 8732

Last Updated: July 2024

Overview

The Massey Ferguson 8732 is a high-powered agricultural tractor equipped with a liquid-cooled, 512.6 cubic inch AGCO POWER 8.4L engine producing 320 hp at maximum power with twin turbochargers. It features a continuously variable transmission (CVT) with infinite forward gears in a low range (0-20 mph) and high range (0-25 mph), and infinite reverse gears in a low range (0-12 mph) and high range (0-18 mph). The engine delivers a maximum torque of 970 lb-ft at 1043 rpm with a torque rise of 46.87% and power increase of 7.07% at 1954 rpm. The closed-center load-sensing hydraulic system has a combined pump flow capacity of 53.1 gal/min at 2435 psi and can exert a maximum force of 22860 lbs at the hitch points. The tractor's fuel efficiency at standard PTO speed (999 rpm) is 17.49 Hp-hr/gal. With a 25270 lb operating weight, the 8732 model is built for heavy-duty tasks.
