Humans invented agriculture to provide for their needs, and the development of tractors was probably the biggest step in agricultural advancement.
And the technology developed for agricultural land quickly gained popularity and became helpful in backyard gardens and yards. John Froelich created the first gasoline-powered tractor in 1892.
But John Deere is one of the most well-known tractor manufacturers today. The company has significantly facilitated manual labor through its selection of garden tractors and mowers.
The John Deere 400 series was one of those garden tractor lines. The John Deere 400, the first tractor in this line, debuted in 1975 and remained in production through 1983.
Later, it was followed by 420, 425, 430, and 445. This one-of-a-kind lawn tractor had brand-new features and a body design, making it popular. It was ahead of its time. This tractor was praised for its wealth of features and for working with various attachments.
Don’t you think it would be worthwhile to write an entire post about this fantastic John Deere 400-riding tractor? We answer in the affirmative! The specifications and features of the John Deere 400 tractor are spheres.
Why the John Deere 400 a Special Series?
There are lots of tractors that John Deere has produced that were celebrated. But there is something special about the JD 400 riding lawn tractor series. But what is it? Let’s dig in!
As previously mentioned, the John Deere 400 series debuted in 1975 and continued through 2001, with the JD 445 serving as the series’ final model. And the “versatility” of this tractor series makes it so well-liked.
The models came equipped with some of the most powerful features that continue to astound John Deere fans. The engines on the tractors in this series, which were designed for domestic and industrial use, ranged in horsepower from 20 to 22.
Due to their powerful engines, dependability, and cutter width of 48 to 60 inches, they are ideal for trimming 3 to 5 acres of grass. In addition, this series has an advantage thanks to the added power it packs, which also allows it to accommodate more attachments.

John Deere 400 Features in Detail
Already impressed with the John Deere 400? Well, don’t be so soon, as the best part is yet to come. We will go over the features of the John 400 in more detail in this section.
We’ll go over every crucial detail of this marvel machine, from general specifications and engines to attachments. So let’s get started without holding it any longer!
Like its successor, the John Deere 420, the 400 is a sizable tractor. How do we know this? Well, by looking at its dimensions- 76″ X 49″ X 44″ (LXWXH).
As far as its weight is concerned, this tractor weighs around 975 lbs, a bit less heavy than the John Deere 420, which weighs around 993 lbs. And this lawn tractor is indeed heavier than the norm, which could be a drawback.
There are several similarities between the JD 400 model and its successor, the 420. Would you love a comparison? Let’s do some straightforwardly.
|Features||John Deere 400||John Deere 420|
|Dimension||76” X 49” X 44”||77″ X 51.5″ X 47.5″|
|Weight||975 lbs||993 lbs|
|Engine||Kohler KQ532||Onan B48G|
|Gross Power||19.9 hp||20 hp|
|Wheel Base||52 inches||52 inches|
|Fuel Tank Capacity||4.5 gal||6.5 gal|
|Transmission||Shaft-driven hydrostatic||Shaft-driven hydrostatic|
What makes this tractor sturdy is its welded body that is powder coated to be rust and corrosion-free for years to come. The color coding is also very attractive and is complete “John Deere” type- yellow and green.
The wheelbase is 52 inches, making turning in tight corners easy. If you’re curious about the kind of operator cabin, it is an open one with a seat for the operator.
Among other features, this tractor also includes the option to attach a three-point hitch, a rear PTO drive, three spools of hydraulics, and a two-speed hydrostatic transaxle.
Additionally, like the JD 420, this model also features three levers on the deck, four hydraulic ports on the front, and the option to attach a three-point hitch. Cool, isn’t it?
But on the downside is the noise. Yes, the John Deere 400 does not cancel noise while operating. Although the noise is not that bothersome, it may initially cause some level of disturbance.
However, because it is an outdated model and the tractor you will receive is a refurbished version, we always advise you to check its components. If you do not purchase a well-maintained or serviced JD 400, you may have to deal with issues like pump leaks, transaxle leaks, worn PTO pulleys, etc.
The John Deere 400’s engine deserves special attention. The air-cooled, horizontal shaft, v-twin Kohler KQ532 engine is strong and reliable enough to meet most of your gardening needs.
The JD 400 engine is a gasoline-powered unit with 879 cc of displacement and 19.9 horsepower. In a nutshell, this engine is dependable in addition to being powerful for its time. The John Deere 400 is still in high demand enables us to attest to this.
However, the tractor’s gross power in relation to its displacement rate throws us off. Compared to later models or more contemporary tractors, the 19 horsepower is considerably less.
The displacement, however, is quite impressive. The engine would have only been of the “bang-on” type if the gross power had been higher.
If we shift our attention, however, we can see some of the engine’s better characteristics, such as its 3.38×3.00-inch bore and stroke, 4.5-gallon fuel capacity, and 3500 rpm rated speed. Also, the feature of the air-cooling system is great, as it demands less maintenance.
The John Deere 400 has an electric start, just like the other tractors in this series.
An electric start option makes it incredibly convenient to start the engine without accelerating. A 12 V battery is a feature of the John Deere 400 that also makes it simple to start the engine in below-freezing temperatures.
The John Deere 400’s fuel tank has a capacity of 4.5 gallons. Although the fuel tank’s capacity is lower than its successors, this is not entirely unfortunate. This will make it simple for you to mow a small to medium-sized lawn and complete other landscaping tasks.
Transmission and Chassis
The vehicle’s transmission is what makes it run efficiently. The John Deere 420 has a hydrostatic shaft-driven transmission and a 4 X 2 2WD chassis, just like its successor, the John Deere 425.
The Sundstrand transmission makes it possible for the tractor’s components to transfer energy effectively. Additionally, the tractor has an infinite forward speed of 10.8 mph and an infinite reverse speed of 4.0 mph.
The icing on the cake is that it has a 5.5 qt capacity for transmission oil and power steering. Finally, it is a mechanical shoe brake, speaking of brakes.
The actual foundation of a tractor is its tires. These unsung heroes are responsible for evenly dispersing the vehicle’s total weight. The John Deere 400 has substantial tires.
They effectively support the tractor’s weight, which in this instance is 975 lbs. The tractor also travels all over your farm. Because of this, they are crucial.
The wheelbase of the John Deere 400 tractor is 52 inches. The rear tires are 26×12.00-12, and the front tires are 18×8.50-8.
The PTO’s primary function is power transfer from the tractor to the attachments. The front and back PTOs on the John Deere 400 are each independent and furnished with a mechanical clutch.
Its rear PTO rotates at 840 rpm. The mechanical clutch, which is unusual these days and caught our attention while reviewing this tractor, is what caught the most of our attention.
Additionally, it is not present in the JD 400 series’ later tractors; an electric clutch is used instead. Although the mechanical clutch is not inherently bad, it does not operate as smoothly as the electrical one. Additionally, they need adjusting and frequently feel heavier.
On the plus side, the mechanical clutch is a straightforward system and is simpler to maintain or repair.
The operator’s cabin on the John Deere 400 is open. Naturally, this improves the tractor’s appearance and makes it simple for the rider to get on and off. However, this system is not beneficial in terms of safety.
An open cabin won’t protect the operator from the elements’ effects or harm during unintentional turnover. Furthermore, the operator’s seat does not have an armrest. After prolonged use, the lack of this feature may result in hand strain.
Now let’s discuss the available attachments. If you recall, we mentioned in the first sections that the John Deere 400 lawn tractor was well-liked due to some of its innovative features at the time.
One of those features is the capability to attach various pieces of landscaping equipment.
With this model’s rear PTO and the choice of three-point attachments, heavy loading equipment is a breeze and hassle-free. For example, one can mount the following attachments on the John Deere 400 lawn tractor.
- Mid-mount 60-inc
- Front-mount 46-inc snowblower
- 54″ front-mount blade
- John Deere 20 loader
- John Deere 450 backhoe
Tillers, plows, and other ground engagers can be attached to garden tractors.
