Its 75 PTO horsepower made it well-suited for operating implements like mowers, balers, and rotary cutters, establishing it as a versatile workhorse on the farm.

The John Deere 6600 was introduced in 1972 as part of the 'Iron Horses' series, replacing earlier models and offering advancements in operator comfort and performance.

This engine is known for its durability and fuel efficiency. The tractor came standard with a Syncro Range transmission, offering 8 forward and 4 reverse gears, providing a good range of speeds for various field operations. It delivered around 75 PTO horsepower, with a 540 RPM PTO shaft. The hydraulic system had a capacity of around 18 GPM, with typically two remote valves available. The 3-point hitch was a Category II, allowing for a wide range of implements to be used. The 6600 was commonly used for row crop work, hay production, livestock operations, and tillage. While similar to the 6400 and 6600, it offered more power than the smaller models in the lineup, making it suitable for heavier tasks.
