Introduction
New Holland TG255 Row-Crop Tractor
The New Holland TG255 is a high-horsepower row-crop tractor produced between 2002 and 2006 at the New Holland facility in Racine, Wisconsin, USA. Designed for intensive agricultural operations, it combines robust mechanical engineering with advanced hydraulic and transmission systems to meet the demands of large-scale farming.
Engine Specifications
The tractor is powered by a 505 cubic inch (8.3 L) CDC 6-cylinder, 24-valve turbocharged and aftercooled diesel engine. It generates a rated power of 255 hp (190.2 kW) at 2200 engine RPM. The engine features a 17:1 compression ratio, liquid cooling, and a dry two-stage air cleaner system to ensure performance under varying environmental conditions.
Transmission and Drivetrain
The TG255 is equipped with a full power shift transmission offering 18 forward and 4 reverse gears. An optional creeper configuration is available, expanding the range to 24 forward and 6 reverse gears. Power is transmitted via an electro-hydraulic wet disc clutch, and the tractor features a 4WD system with an electro-hydraulic differential lock to maximize traction.
Hydraulics and Hitch
The hydraulic system utilizes a closed-center load-sensing design, providing a standard pump flow of 38.6 gpm (146.1 lpm) at a pressure of 2930 psi. An optional Mega Flow system increases flow capacity to 68 gpm (257.4 lpm). The rear hitch is a Category III/IIIN type with electronic draft control, capable of lifting up to 14,970 lbs (6,790 kg) at 24 inches behind the lift point.
Dimensions and Operator Environment
The tractor sits on a 121.2-inch wheelbase and features a standard air-conditioned cab for operator comfort. Maneuverability is enhanced by power steering and available SuperSteer front axle options. The machine is typically configured with 16.9R30 front tires and 20.8R42 rear tires to maintain stability and ground clearance.
Conclusion
The New Holland TG255 is engineered for heavy-duty traction and implement management. With its substantial lift capacity, flexible transmission options, and high-flow hydraulic potential, it is well-suited for professional agricultural environments requiring high productivity and reliability.
