Introduction
New Holland TJ450 Four-Wheel Drive Tractor
The New Holland TJ450 is a high-horsepower four-wheel drive tractor produced between 2002 and 2005. Manufactured in Fargo, North Dakota, USA, it shares its platform with the Case IH STX450. This machine belongs to the TJ series, designed for heavy-duty agricultural operations requiring significant traction and power.
Engine and Performance
The tractor is powered by a Cummins QSX 15, a 14.9-liter, 6-cylinder turbocharged and aftercooled diesel engine. It delivers 450 horsepower at a rated speed of 2000 RPM, producing a torque of 1743 lb-ft (2363.5 Nm). The engine utilizes a liquid-cooling system and a dual-element air cleaner to maintain performance under heavy loads.
Transmission and Drivetrain
The drivetrain features a full power shift transmission providing 16 forward gears and 2 reverse gears. Power is transferred via an electro-hydraulic wet disc clutch to a four-wheel drive system, supported by compound planetary final drives and hydrostatic power steering for improved maneuverability.
Hydraulics and Hitch
The hydraulic system is a closed-center, load-sensing type, designed to optimize flow for various implements. It provides a standard total flow of 40 GPM (151.4 LPM), with optional configurations reaching up to 90 GPM. The rear hitch is a Category IVN/III type with a lift capacity of 19,500 lbs (8,845 kg) measured at 24 inches behind the lift point.
