John Deere 1840F Tractor Parts

The John Deere 1840F, introduced in the early 1980s, quickly became a staple on farms seeking a versatile and dependable utility tractor. It was designed to handle a wide range of tasks, from field work to loader operations. At its heart was a Yanmar 3T90J diesel engine, a 3-cylinder powerplant displacing 90 cubic inches (1.5 liters) and producing approximately 52 horsepower. This engine provided a good balance of power and fuel efficiency, making it economical to operate. The 1840F typically came equipped with a gear-driven transmission, offering 8 forward and 4 reverse speeds. This provided a good range of options for matching ground speed to the task at hand. The independent PTO delivered around 47 horsepower at 540 RPM, enabling the tractor to power a variety of implements. The hydraulic system had a capacity of around 9 GPM and typically featured 2 remote valves, allowing for operation of hydraulic cylinders on implements. The 3-point hitch was a Category II, offering a lift capacity of around 2600 lbs, making it suitable for attaching a wide array of implements. Compared to other models in the John Deere lineup, the 1840F offered a good combination of size, power, and features. It was larger and more powerful than smaller compact tractors, but more nimble and affordable than larger row-crop tractors, making it a popular choice for small to medium-sized farms engaged in hay production, livestock operations, and light tillage.
