Introduction
Cameco 345-B Four-Wheel Drive Tractor
The Cameco 345-B is a heavy-duty four-wheel drive tractor produced between 1976 and 2006 in Thibodaux, Louisiana, USA. Designed for demanding agricultural applications, this machine is recognized for its robust construction and high-torque engine performance.
Engine and Performance
The tractor is powered by a John Deere 6081 6-cylinder, liquid-cooled turbocharged diesel engine, which replaced the Caterpillar 3306 model in 2003. It delivers a rated power output of 250 hp (186.4 kW) at 2200 RPM and produces 808 lb-ft (1095.6 Nm) of torque at 1500 RPM. The engine utilizes a 1-5-3-6-2-4 firing order and requires 30 quarts (28.4 L) of oil for lubrication.
Transmission and Drivetrain
The 345-B offers versatile transmission configurations, including an 11-speed power shift transmission providing 11 forward and 3 reverse gears. An alternative Allison transmission option features 10 forward and 2 reverse gears, utilizing a five-speed transmission with a torque converter and a two-speed transfer case. Power is delivered to the ground via four-wheel drive and inboard planetary final drives.
Hydraulics and Hitch
The hydraulic system is an open-center type with a pump flow capacity of 25 gpm (94.6 lpm) operating at a pressure of 2000 psi (137.9 bar). The system reservoir has a total capacity of 57 gallons (215.7 L) and supports between 2 and 5 valves. The rear hitch is compatible with Category III implements.
Operator Environment and Chassis
Operators are provided with an open station, with an air-conditioned cab available as an optional upgrade. The tractor features hydraulic wet disc brakes for stopping power, with optional air brakes available for trailer operation. The unit has a shipping weight of 23,400 lbs (10614 kg) and a ground clearance of 20 inches (50 cm).
Conclusion
