John Deere 4520

john deere 4520

John Deere 4520 actually refers to 2 different John Deere tractors. The original is the first John Deere tractor model to come with a standard turbocharger. This was necessary as the John Deere 4520 was used (and is still used) primarily as a work and pull tractor. The latest model is the 4520 compact tractor. This article will cover both tractors. First the original tractor, then the newer compact tractor.

The Original John Deere 4520 was built at the Waterloo, Iowa plant for just one year, from 1969 to 1970. DuringJD 4520 this time, more than 7,894 units were built with an open operator cab. All of them came with a standard 6-cylinder John Deere diesel engine that pumped 123 hp. It had a displacement of 6.6 liters and, as mentioned above, it was also turbocharged.

The engine has a liquid cooling system that requires 26.5 liters of coolant to function properly. The power produced by the engine is transmitted through a series of transmissions. The first is the Syncro-Range transmission, partially synchronized, which gives you 8 forward gears and 2 in reverse. The other option is the Power Shift transmission, which provides 8 forward speeds and 4 reverse.

The top speed the stock John Deere 4520 can reach is 21 mph. You can choose between Category 2 and Category 3, with a 3-point hitch. Being such a powerful tractor, it is logical to assume that it also weighs a lot. Once ballasted, the John Deere 4520 weighs 8162 kg (17,995 pounds).

This tractor can fit 9.50-20 front and 9.50-20 rear agricultural tires. This John Deere 4520 is powerd by a diesel engine it has 404 ci or 6.6 L 6 cylinders the fuel tank capacity is 50 gal or 189.3 L. This machine has 4×2 2WD wheel drive system, 8 out Forward & 4 Reverse John Deere Power Shift Transmission System.

The new model is offered with the option of a ComfortGard cab or just a roll bar. In addition to having a rear PTO as standard, the new JD 4520 also comes with the option of a center PTO that will allow you to attach up to a 72-inch center-mounted mower deck to cut large areas.

john deere 4520 compact tractor


I ordered it with an extra hydraulics to drive an adjustable front loader mounted snow blade and 3 point adjustable arms. I have had it for 10 years and there have been absolutely no problems. Summer version: Woods 7 ft. 3-point mower and bucket. Winter version: front hydraulic blade and 6 1/2 ft box grader in rear. I have air conditioned cab and 400X loader. It is the best investment I have ever made. It replaced a John Deere 5310 that was too big. It’s a great size and packs a lot of power, as well as a ton of features.

Since purchasing the 4520 Cab Tractor, I have found the John Deere Power Tech engine to have incredible low-end torque compared to the competition, and the overall quality and weight of the components are excellent. The electronic throttle helps me a lot in loader work and the ePTO option is a real fuel saver.

The tractor cab is exceptional. All controls are within easy reach, making it easy to operate the tractor, implement, control the 3-point hitch and control the loader. However, with any tractor, not everything is perfect. The wheelbase could be a bit longer to smooth the ride and the eHydro could use a few more ranges, such as having a function. Except for the little details, this is a tractor you won’t regret owning.

I bought this tractor with almost 200 hours on it. With it I also have a blade, 6 King Kutter, and a 2-stage snow blower. I’ve put in about 250 hours of blowing snow, tilling, digging, logging, and a million other odd jobs since then. I have made several other attachments since I bought it, including a 6-tooth S cultivator, a single and two shank ripper / subsoiler, and a 3 point trailer hitch adapter. The EHydro is great, the charger is surprisingly robust and easy to disassemble, the heating and air conditioning work very well, and it packs plenty of power for everything I’ve asked it to do. So far I can’t find a single thing to complain about.

The tractor has an excellent fit and finish. It has excellent pulling power, I was plowing a new food plot with 3 bottom plow, Harry Ferguson mfr. and he turned around and the plow was totally underground. The tractor never slowed down or stalled, I just picked up the plow on the go and kept going! I would recommend this tractor to anyone who needs a compact Tractor that I move on a car hauling trailer pulling everything with a 1997 Chevy Tahoe!

I had a brand new 2002 Kubota L4300 and was never happy with it because the hydro pedal was very uncomfortable to operate and the charger joystick was also in a strange position. So I bought a 2006 JD4520 with a cab and I am very happy with it.

I had a model of 1969. He was a Mr. but they also became ps. It was Deere’s first Turbo Ed tractors and they did it well. They were made in the ’69 and ’70. The latter were inter refrigerated. They had double air filters from one stage with a bee honeycomb prefilter aspired by the escape that was very effective.

According to JR Hobbs, they had failures in the air filter (fires) and changed to the 4620 design with a single primary / secondary air filter system. Mine was still with the original design and I had no problems with him. As I said, the pre-filter worked very well. Deere developed the tire 20.8 38 for 4520. I still have an original brochure when they were new to explain that fact. Mine had between 9000 and 9500 hr when I sold it (I wish I had it yet).

The engine was all original (except that I put a new set of bearings at 7200 hr just in case. A friend had a 4620 that a crankshaft was loaded at the time) and he still started well. The boot engine bushings were worn, which made it rotate quite slowly. The key was turned and the boot engine staggered by turning the engine very slowly and always lit and started.

I checked the boot engine (I did not realize at that moment as evil I needed work) and it was surprising how much faster than it turned. The answers that argued that it was a heavy weight as a 5020 are simply erroneous. The 4520 was very agile, not like a 5020 at all.

The 4520 are physically much larger than a 4020 but relatively speaking they are equally maneuverable. (I also have a 4020) was a very comfortable driving tractor. They had a power of 122 cv. I also had a 4250 at the same time. It had a power of 120 hp. These two tractors were very similar in terms of traction performance, weight (had been configured with radial 20.8 38 double, recommended ballast and division of front / rear weight) and horses-hour / gallon according to Nebraska’s tests.

The 42 could work better than 45 at times by having double the selection of marches. 45 and 42 were equal in terms of maneuverability. The 45 was indeed a great design tractor, since it weighed the same without a cabin than 42 with cabin. There was a 4520 near here for many years with a conversion to Detroit 8V-71 and the transmission and the rear lived. I can say that I miss this tractor.
