If you keep on reading us till the very end, you will have a clear idea about the tractor and whether it’s the best choice for you or not. A complete guide with detailed features is given below to make your decision easier. 

#1. Physical Specifications

First, let’s look into the physical specifications of the tractor. 

The John Deere E120 is made for lawns and gardens that weigh around 198kg or 436lbs. The tractor has a wheelbase of 1240 mm (48.8 in). Having this much wheelbase will save your time while mowing the land.

John Deere E120 is an old tractor but one of the best John Deere products. It can hold a lot of power to mow land, and the plus point is that it is easy to operate. In addition, the construction quality is great, making it a reliable choice for landowners. 

Apart from this, it has very comfortable seats positioned higher than normal, which results in better back support.

#2. Engines

The E120 tractor uses the engine of the Briggs and Stratton 40N877 model. Additionally, it features a four-stroke, air-cooled, and a v-twin engine. The tractor also comes with a 2-cylinder gasoline-powered engine. It also has a mechanical fuel gauge that can easily be viewed from the operator seat. This is made in such a way so that you can easily know when you’ll run out of fuel.

Talking about the capacity of the tank, it’s 2.4 US gal/ 9.1 L., and due to the presence of a two-cylinder engine, it can work in silence. This is, supposedly, the best thing about its engine that no one will be disturbed by the noise. 

As it uses an electric starter, you don’t need to provide acceleration before starting it. All you have to do is turn on the engine, and it is good to go. The engine can create high power with a displacement of 0.7 L, 656 cm², the engine can create high power. It has a 750 mm by 730 mm bore and stroke.

Since a high-powered engine is excellent for mowing purposes, the E120 tractor’s engine comes with 20 HP, making it a great choice for a garden and lawn tractor. It will show bests results when used on land less than 1 acres. So much powerful engine would allow you to do many tasks instead of mowing and clearing.

#3. Fuel Tank

The fuel tank is present at the rear position. It holds a fuel capacity of around 2.4 US lbs or 9.1 liters. And you should know that this tractor uses gasoline to ignite itself. An interesting thing about this tractor is that it follows 3- seconds oils changing system. It mainly means that the process is easy, quick, and clean, and you don’t need to drain the oil from the engine. 

#4. Transmission and Chassis

The engine uses its 20 HP power to divide it across various parts without any hassle to work efficiently. Transmission helps the power move to the parts where it is actually required. The transmission model that is required here is Tuff Torq TL200. The hydrostatic transmission provides several choices for ground speed.

For the tractor to function efficiently, the engine has to use its 20 HP properly and divide it across the tractor’s various parts. And it is the transmission that helps the engine to move the power to the tractor’s parts. 

Transmission and Chassis

This tractor’s transmission type is hydrostatic, which allows the rider to ride this tractor for an extended period. It has infinite forward and reverses gears. The maximum forward speed is around 8.9 km h (5.5 mph), and the maximum reverse speed is around 5.2 km h (3.2 mph).

The 4×2 two-wheel-drive chassis has a full-length welded steel frame that protects it from corrosion or rust. In addition, it is coated with an e-coat/primer that is resistant to UV rays. It also prevents fading of paint after some time. 

Another specialty of E120 tractors is a wet disc brake on the left side of the tractor instead of the right side. Although it may be new to many people, you will be used to it after a few days. The manual steering makes it quite comfortable to use it. The manufacturers made it up with an 18″ turn, making it easy to turn right.

#5. Frame

The frame is made of full-length welded steel to make it reliable for owners. The solid frame is made up of 12 gauge, 0.105 in steel. 

#6. Safety

This tractor comes with an open service platform, prone to accidents, as far as safety is concerned. We say so because, in case of any turnarounds, there might involve a high chance of getting injured. Furthermore, an open working station means no protection from rain or wind.

On the other hand, its strong 12 gauge steel frame offers a sturdy, durable, and rust-proof body that guarantees lifelong usage. 

#7. Attachments

The tractor also has some of the best attachments that you can ask for. It will help you achieve tasks more efficiently. It comes with a 42″ mower deck attachment option that can easily be adjusted using a level.
