Introduction
Massey Ferguson 451 Utility Tractor
The Massey Ferguson 451 is a utility tractor produced in Brazil between 2002 and 2006. As part of the 471 series, this machine is designed for general agricultural operations, prioritizing mechanical reliability and operational versatility.
Engine and Performance
The tractor is powered by a Perkins 903.27 liquid-cooled diesel engine. This 3-cylinder unit has a displacement of 2.7 liters and delivers a net power output of 48 hp (35.8 kW) at a rated speed of 2200 RPM. The engine features a thermostart pre-heating system and a dual dry element air cleaner to ensure consistent performance in various environmental conditions.
Transmission and Drivetrain
The 451 offers two transmission configurations: a standard 8-speed gear transmission and a partially synchronized version with a left-hand shuttle. Both options utilize a 305mm dry disc clutch to manage power delivery. The tractor is available in either two-wheel or four-wheel drive configurations, supported by power steering and wet disc brakes to facilitate maneuverability and safety.
Hydraulics and Hitch
The hydraulic system utilizes an open center design with a pump flow of 9.5 gpm (36.0 lpm) and a system pressure of 2500 psi (172.4 bar). It is equipped with two valves and has a reservoir capacity of 11.1 gallons (42.0 L). The rear hitch is a Category II/I system featuring both position and draft control, providing a lift capacity of 3748 lbs (1700 kg) at the link ends.
Power Take-Off (PTO)
The rear PTO system provides a standard 540 RPM speed. Depending on the configuration, this speed is achieved at 1908 engine RPM for the gear model or 1789 engine RPM for the shuttle model. An optional independent PTO with a hydraulic wet disc clutch is available, offering increased flexibility for various power-driven implements.
Conclusion
