The History of John Deere 4320
During the 1960s, the John Deere 4020 tractor era, farmers believed nothing could ever beat the powerful model. Little did they know that John Deere had other heavy-duty equipment up its sleeve at the time.
The John Deere 4020 tractor was a powerful machine at the time of production; however, competitors had more to offer as the years went by. The 4020 could not do all the heavier duty, and the tension to make something even more remarkable was rising.
Around the time, John Deere manufactured the 5020 tractors. The tractor was powerful, reliable, and worked hard for many hours until farmers realized it could not compare even to the 4020. The 133HP 5020 tractors were not cut out for the row-crop operation.
To satisfy the farmers’ needs, John Deere manufactured the row-crop version of the 5020 tractors. However, the version did not reach great success. The tractors were still a bit awkward to manage and incapable of doing much.
Finally, John Deere published the 4320, which was soon marketed as a “Super-4020” tractor. The 4320 tractors produced 115HP, a significant upgrade and a horsepower gap from the 4020 tractors. However, regarding the features, the 4320 did hold an uncanny resemblance to the compared tractor.
Like the 4020 tractors, the 4320 model offered power steering, a rock shaft, power brakes, a single remote cylinder, a three-point hitch that could power most equipment, and Roll-Gard protection. Again, like most John Deere tractors, many farmers could get the various front ends. Besides the standard adjustable wide front end, operators could enjoy the single front wheel, narrow or adjustable front ends, rigid or Roll-O-Matic dual front, or a fixed front end.
The 4320 tractors were produced between 1971-1972, and within the years of production, around 20,000 left the factory.
The 4320 tractor was available only in the row-crop variant. However, a few farmers used it as a standard tractor as well.
Currently, there are two types of 4320 John Deere tractors. The first one is the original version, produced in 1971, while the second version is still produced by John Deere today. The new John Deere is a compact tractor, offering a versatile service to many farmers. The horsepower stands at 48HP, and it’s one of the most desirable tractors. In addition, the newer version is compatible with various attachments, making it a trusty workhorse for novice and professional farmers.

John Deere 4320: Engine
The John Deere 4320 is built with a turbocharged diesel engine. This is a 6.6L 6-cylinder engine that is also liquid-cooled. The inline 6-cylinder diesel engines produce more torque, delivering more power for any agricultural task.
Furthermore, the turbocharged engine can produce more power without risking excessive wear and tear of the engine. However, putting regular gas engines underneath could significantly cause spontaneous detonation.
One of John Deere’s best decisions with the 4320 tractors is supplying it with a diesel engine that can endure turbocharging pressure. Diesel engines are also known for converting up to 45% of fuel into energy, resulting in a fuel-efficient service.

John Deere 4320: Transmission
What makes the John Deere 4320 tractor so unique are the transmission options. The 4320 tractor uses PowrReverser and eHydro transmission.
PowerReverser transmission: this transmission offers 12 gears which provide a wide range of motion for different agricultural work. The transmission uses a wet clutch, both in forward and reverse gears, offering the tractor a long lifespan.
eHydro transmission: The eHydro transmission offers three-range electronic hydrostatic transmission, which features a pump and a motor. The pump and the motor deliver fluids to transmit the engine power. One of the biggest benefits of the eHydro transmission is that you can easily change directions without using the clutch. Additionally, the new tractor offers better cooling.
The old John Deere 4320 tractor was equipped with a Syncro-Range transmission that offered 8-forward and 2-reverse gears. As a result, the all-wheel drive tractor is reliable, especially for snow removal and heavy-duty tasks.

Common Issues With John Deere 4320 Tractor
John Deere 4320 is a good tractor, but as expected, it can run into some problems.
The fuel pump is one of the most frequent issues with the John Deere tractor. The fuel pump often fails in delivering fuel for the engine to work, which can cause a backfire. However, checking the pump is relatively easy and should be done without electrical instruments.
The steering wheel is sometimes difficult to maneuver, especially with the old John Deere model. In addition, the wheel can get stuck sometimes, only allowing some operations to be performed optimally.
Some users have even reported a faulty starter, which can be solved using a voltmeter.
Luckily, the 4320 tractor only shows signs of failure sometimes. With proper maintenance and frequent use, the John Deere tractor can serve you for a lifetime!
