Introduction
John Deere 4040S Row-Crop Tractor
The John Deere 4040S is a heavy-duty row-crop tractor produced between 1981 and 1984 in Mannheim, Germany. As part of the 4040 and 4240 series, this machine was engineered for demanding agricultural operations, combining high-torque performance with the comfort of the standard Sound-Gard cab.
Engine Specifications
The tractor is powered by a 5.9-liter, 6-cylinder turbocharged diesel engine. It generates 115 hp (85.8 kW) at a rated speed of 2200 RPM. The engine produces a peak torque of 324.5 lb-ft (440.0 Nm) at 1200 RPM, providing the necessary pulling power for heavy field implements. It features a liquid-cooling system and a 16.8:1 compression ratio.
Transmission and Drivetrain
Operators can choose between two transmission options: the Quad-Range, offering 16 forward and 6 reverse gears, or the Synchro-Range, providing 12 forward and 4 reverse gears. Both systems utilize a hydraulic wet disc clutch to ensure smooth gear transitions. The tractor is equipped with four-wheel drive, power steering, and wet disc brakes for enhanced maneuverability and safety.
Hydraulics and Hitch
The 4040S utilizes a closed-center hydraulic system operating at a pressure of 2250 psi (155.1 bar). The system provides a pump flow of 25.4 gpm (96.1 lpm), supporting a variety of hydraulic attachments. The rear Type II three-point hitch offers a lift capacity of 10,590 lbs (4803 kg), complemented by an independent rear PTO with 540/1000 RPM settings.
Physical Dimensions
The tractor has a shipping weight of 11,070 lbs (5021 kg) and measures 180.7 inches in length. Its height reaches 123.4 inches at the exhaust and 114.7 inches at the cab roof. The rear tread width is adjustable between 60 and 92.9 inches to accommodate various row-crop spacing requirements.
Conclusion
The John Deere 4040S is a robust, well-balanced tractor suited for medium-to-large scale row-crop farming. Its combination of high-torque engine output, versatile transmission options, and substantial hydraulic capacity makes it a reliable asset for both heavy tillage and general utility tasks in the field.
