As we read through the John Deere 4440 reviews, we frequently observed that farmers were increasingly favoring older tractors. Tractor models manufactured in the ’90s are becoming crowd-pleasers. 

But why so?

We dug a little deeper to discover the answer, which was straightforward enough—farmers desire tractors that are well-made, uncomplicated, and reasonably priced. 

When we spoke to some farmers, they agreed that older tractors are still very much functional and that their repairs are less expensive than those of more recent models.

Along the way, we met a farmer who had just bought a 1979 John Deere 4440. He spent $18,000 to revamp it with automatic satellite-guided steering. And he was pretty satisfied.

One of John Deere’s most well-known tractors from the “Iron Horse” series is the 4440. John Deere, between 1977 and 1982, produced this tractor model. On average, the 4440s have a life between 12,000 and 15,000 hours.

It would be wise to invest in it if you get one. After all, as the saying goes, “They just don’t make ’em like they used to.

History of John Deere 4440 Lawn & Garden Tractor

History of John Deere 4440 Lawn & Garden Tractor

The John Deere 4440 tractor was the most popular model in the Iron Horse line and was manufactured from 1978 to 1982.

This tractor was built at the John Deere plant in Waterloo, Iowa, USA, in both 4WD row-crop and 2WD row-crop configurations. The 4440 tractors are classified as full-sized farm/agricultural tractors.

The John Deere 7.6 L six-cylinder turbocharged diesel engine powers these tractors. Its powerful features made the 4440 the most famous tractor model in the Iron Horse series and established John Deere as the global leader in power and torque.

In addition, all five row-crop tractors in this series come with more challenging internal components that could support the machines’ increased horsepower.

The brand unveiled the other two tractors, the 8440 and 8640, after the initial release of the 4040, 4240, 4240 Hi-Crop, 4440, 4440 Hi-Crop, 4620, and 2840 models.

Finally, the Iron Horse series was completed with the release of four 40-series small tractors: 2040, 2440, 2640, and 2940.

John Deere 4440 Features in Detail

John Deere 4440 Features in Detail

The updated cab of the 4440, which included new cloth seats, an AM/FM radio (the first tractor to have this feature inside a cab), and full in-cab air conditioning and heat, made it incredibly well-liked.

Most customers favored this tractor’s cab. Most of the time, we heard the cab was spotless and incredibly comfy, with the AC and heat serving as the cherry on top. But let’s discuss only some aspects at a time.

Instead, let’s delve into the following subsections, where we’ll examine the tractor in greater detail and highlight some of its most prominent features.

Physical Specifications/ Overview

Let’s talk about the general specifications of the tractor.

It is accurate that John Deere encourages customers to choose some of the company’s renowned older tractor models. The brand claims that the tractors are reasonably priced and that customers can easily find parts at the brand’s dealers.

And one such model that John Deere wants to introduce to its modern customers is the 4440.

The John Deere 4440 immediately caught our attention because it is a large tractor. Why not, then? The 4440 is a row-crop tractor used on sizable farms to grow row crops.

Row crop tractors are made for farming tasks like harrowing, harvesting, and plowing. The 4440 model from John Deere is a powerhouse of features, versatility, power, and efficiency.

It was therefore intended to be substantial. It’s common to find this “classic” in such good condition at auctions, and it’s hard to believe these tractors are more than 40 years old.

The JD 4440 measures 158.5″ X 96″-119″ X 117.3″-128.7″. The weight of this tractor ranges from 11780 to 15775 pounds. A heavier one, for sure! The dimensions of the tires are 10.00-16 in the front and 18.4-38 in the back.

The body of the tractor is green, with yellow borders and wheels. The tractor still manages to move and compete with its modern counterparts thanks to its welded, svelte body.

According to the brand, the 4440 model is a special, one-of-a-kind item, and only a few JD fans are aware of it. Moreover, the truth is that this model has several innovative features for its time.

The tractor’s cab was undoubtedly what surprised us the most. It has an AC and heating system and a four-post ROPs system! Can you believe it? These features were quite sophisticated for the late 1990s.


The John Deere 4440 tractors fitted the powerful John Deere 7.6 L six-cylinder turbocharged diesel engine. 4.5625×4.75 inches are the bore and stroke, and the compression ratio is 14.9:1. 

The maximum horsepower available from the engine is 130 hp or 132 PS. The 4440 also features a rear-independent power take-off with 540/1000 RPMs. The pressurized lubrication system used by the tractor’s diesel engine includes the following features.

  • a direct injection fuel system
  • a full-flow filter
  • an inline fuel pump
  • an air filter of the dry type with a safety element
  • a centrifugal pump-powered dual-pressure cooling system
  • two powerful thermostats

Note: Direct fuel injection is a feature that improves engine performance while also lowering exhaust emissions. But this feature requires regular upkeep. The fuel pump can avoid being clogged with carbon buildup if appropriately maintained.

Electric Start

How can it miss the electric start when so many advanced features exist in the John Deere 4440? Much like other JD tractors and riding lawnmowers, the 4440 also comes with an electric starter powered by 2 batteries with a voltage of 6 V and 850 CCA.

The batteries charge best at 61 amps (ROPs) and 72 amps (Cabs). Thanks to the electric starter, this tractor can be started even in extremely cold temperatures without needing acceleration.

Fuel Tank

The fuel tank on the John Deere 4440 holds 65 gallons of fuel. This will allow you to work on a medium to large-sized farm easily.

Transmission and Chassis

Two transmission options are available for the John Deere 4440 tractor: partial power shift (16 forward and 6 reverse gears) and full power shift (8 forward and 4 reverse gears). The JD 4440 also has a pedal-activated hydraulic differential lock, hydraulic wet disc brakes, and full-power hydrostatic steering.

The hydrostatic transmission, which allows for variable output speed does not limit the tractor’s speed. Another feature that distinguishes the John Deere 4440 as a desirable tractor is its full hydrostatic power steering.

Users will gain better control over the vehicle, simple movement, and refined turning from this tractor. On the other hand, the tractor can be stopped instantly in challenging conditions thanks to the differential hydraulic wet disc brake. Furthermore, this brake system is reliant and needs little maintenance.

The John Deere 4440 tractor has an available HFWD 4WD system in addition to the standard 2-wheel drive. The weight of the various systems ranged from 11780 to 15775 lbs.


The tires of the John Deere 4440 have a sizable footprint and can support heavy loads even at low inflation pressures. Along with distributing the tractor’s weight, the tires also lessened the force the machine applied to the ground.

As a result, insufficient coil compaction is guaranteed. In addition, flotation tires have a large contact patch that allows them to tread more on the ground, resulting in better traction.

The front and rear treads of the JD 4440 measure 55.7 to 93.2 inches and 60 to 130 inches, respectively, while the wheelbase is 106.7 inches.


The John Deere 4440 comes with a single- rear- PTO. The rear PTO makes it possible to load attachments. With 540/1000 RPM, the rear PTO spins independently.

Operator’s Cabin

The John Deere 4440 is a solid performer that is still being used on farms all over the nation. Here is some historical trivia for you before we dive right into learning about this tractor’s operating system.

Before 1975, cabs on farm tractors used to be brought and fitted afterward. It simply meant that farmers would purchase the tractor first, after which they could buy the glass cab and have it installed.

As a result, the additional cabs needed to blend in better. They could have been more spacious and comfortable. But things started to improve when John Deere noticed this problem and altered how agricultural tractors were constructed.

The manufacturer made sure to include a built-in, cozy operator’s cabin for the 4440 and its siblings so that the rider could sit comfortably while also being protected from the elements.

And it was this very thing that gave the John Deere 4440 such a big fan base. The tractor came standard with a Sound-Gard cab that sat on rubber bushings rather than bolting to the frame.

As a result, the rider felt fewer vibrations while operating the tractor. In addition, the front glass was curved and angled to direct noise away from the operator. Additionally, the Four-post ROPS was available as an option. The cab’s other features included brand-new fabric seats, an AM/FM radio, and full heating and cooling.
