Last Updated: July 2024

Overview

The Massey Ferguson 7624 is a robust row-crop tractor manufactured by AGCO S.A. It features a front wheel assist chassis, hydrostatic steering, and a Continuously Variable Transmission (CVT). The tractor is powered by a 6-cylinder, turbocharged air-to-air aftercooled Sisu Diesel engine with a compression ratio of 17.8 to 1, using Fuel No. 2 Diesel. The engine has a displacement of 449 cubic inches and is rated at 187.5 hp at 2100 rpm. The operating weight is 18695 lbs, and the wheelbase is 117.8 inches. Key features include a QuadLink Suspended Front Axle, SCR Emission Control, and an Electronic High-Pressure Common Rail Fuel System. The hydraulic system has a flow rate of 30.0 GPM at minimum pressure and 36.2 HP at maximum power, with a three-point hitch maximum lift capacity of 13715 lbs. The sound level at no load in 10th gear is 70.0 dB(A).
