Knudson 310 Four-Wheel Drive Tractor
The Knudson 310 is a heavy-duty four-wheel drive tractor produced between 1974 and 1978 in Crosby, North Dakota, USA. Designed for large-scale agricultural operations, this machine focuses on high-output traction and structural durability.
Engine and Performance
The tractor is powered by a liquid-cooled Cummins NT-855-310 turbocharged diesel engine. This 6-cylinder powerplant features an 855 cubic-inch (14.0 L) displacement and delivers 310 horsepower at a rated speed of 2100 RPM. With a torque output of 852 lb-ft at 1600 RPM, the engine is configured to provide consistent pulling power for demanding field implements.
Transmission and Drivetrain
Power is managed through a Spicer-Dana 1262 gear transmission, offering 12 forward and 2 reverse speeds. The system incorporates a Rockwell T-228 two-speed transfer case and utilizes 394mm cerametallic clutch discs for power transfer. The drivetrain features planetary final drives and a permanent 4x4 configuration, complemented by power four-wheel steering to assist in maneuvering the machine's substantial frame.
Hydraulics and Dimensions
The hydraulic system utilizes an open-center design equipped with three rear valves for implement control. Physically, the tractor measures 262 inches in length and 174 inches in width, with a wheelbase of 144 inches. Its maximum operating weight is rated at 24,000 lbs, supported by 23.1-26 tires on both the front and rear axles.
