Introduction
Acremaster 404 Four-Wheel Drive Tractor
The Acremaster 404 is a heavy-duty four-wheel drive tractor produced between 1980 and 1984 in Merredin, Australia. Designed for large-scale agricultural operations, this machine focuses on high-torque output and structural durability.
Engine and Performance
The tractor is powered by a Mercedes-Benz OM404 liquid-cooled V12 diesel engine. With a displacement of 20.9 liters (1276 ci) and a compression ratio of 17.5:1, the engine produces 390 horsepower (290.8 kW) at 2200 rated RPM. This configuration provides the necessary power for demanding tractive tasks.
Transmission Options
Operators have access to two distinct transmission configurations to suit specific field requirements. The standard Acremaster gear transmission offers 9 forward and 3 reverse speeds. Alternatively, a Twin Disc 1400 power shift transmission is available, providing 12 forward and 2 reverse speeds for improved efficiency during heavy load transitions.
Mechanical and Dimensions
The 404 features an articulated power steering system to manage its substantial frame. The machine measures 664 cm in length, 450 cm in width, and 359 cm in height at the exhaust. With a total weight of 15,000 kg (33,069 lbs) and matching 24.5x32 agricultural tires on both axles, the tractor is engineered for maximum traction and stability. A climate-controlled cab is included as standard equipment to support long operational hours.
Conclusion
The Acremaster 404 is designed for heavy agricultural duty where high power and mass are critical. Its combination of a Mercedes-Benz powertrain and robust chassis makes it suitable for large-scale soil cultivation and primary tillage operations.
