John Deere 6600 Overview
The John Deere 6600, produced from 1992 to 1997, is a versatile and reliable row-crop tractor that has proven itself in various agricultural tasks. Equipped with a robust 6.8L 6-cylinder diesel engine generating 118 horsepower, this model is known for its strong performance and durability. The tractor offers two transmission options: a 16-speed PowrQuad and a 20-speed PowrQuad, both designed to provide smooth and efficient power delivery across different terrains.
One of the standout features of the 6600 is its advanced hydraulic system, which is closed-center and pressure-flow compensated, delivering up to 29 gpm of total flow. This system is particularly beneficial for operating hydraulic implements that require consistent power. Additionally, the hydrostatic power steering and hydraulic wet disc brakes contribute to the tractor’s ease of operation, even during long working hours.
The cab of the John Deere 6600 is another highlight, offering a spacious and comfortable environment with air conditioning, which was a premium feature during its production years. The cab’s design prioritizes operator comfort, reducing fatigue during extended periods in the field.
Some users have reported issues with the dry disc clutch, particularly in older models where wear and tear have become more apparent. This can lead to the need for more frequent maintenance or eventual replacement. Another common concern is the complexity of the hydraulic system, which, while advanced, may require specialized knowledge to service properly.
Despite these challenges, the John Deere 6600 remains a popular choice among farmers due to its reliable engine, versatile transmission options, and comfortable cab. It’s well-suited for medium to large-scale farming operations, where its power and advanced features can be fully utilized. On forums and in farming communities, the 6600 is often praised for its durability and the overall value it provides to its owners, even years after its production ceased.
