John Deere 4840 Tractor Parts

The John Deere 4840 was introduced in 1978 as part of the 'Iron Horse' generation, replacing earlier models and offering increased power and improved features. It was produced until 1982. The heart of the 4840 is the John Deere 619 cubic inch (10.1L) inline 6-cylinder diesel engine, producing approximately 176 horsepower. This engine provided ample power for a variety of tasks. The tractor featured a Quad-Range transmission, offering 16 forward and 6 reverse speeds, providing operators with a wide range of gears for optimal performance in various field conditions. The 4840 delivered around 145 PTO horsepower at both 540 and 1000 RPM, allowing for versatile implement compatibility. Its hydraulic system boasted a flow rate of approximately 30 GPM, powering multiple remote hydraulic circuits. The 3-point hitch was a Category III, providing ample lift capacity for heavy implements. Commonly used in row crop farming, hay production, and general tillage operations, the 4840 distinguished itself from smaller models with its increased horsepower and heavier build, while offering a more economical option compared to the larger frame John Deere tractors of the time.
