Detailed Features of John Deere S140

Detailed Features of John Deere S140

We hope you got a general idea about John Deere S140 from the above tables. Now, let us go into depth and look into its details. 

To begin with, we will discuss the general and physical specifications of this tractor. The S140 model is pretty compact for users to navigate easily. Furthermore, we will be discussing its engine, electric start, transmission, chassis, mowing deck, and other features. 

Physical Specs

The tractor’s body color is the first physical characteristic that draws your notice. The S140 is colored in a green and yellow mix, typical of John Deere’s color scheme. Through this body color, you can identify the product in the very first place.

Now let’s pay some attention to the tractor’s dimension. It is essential to focus on the dimension because not every sized tractor will suit every lawn. Usually, a compact tractor tends to be the most suitable for a typical home yard or lawn, although we are not generalizing it. That being said, the S140 has the dimension of 69.7″ x 51.7″ x 44″ (l x w x h), which is ideal for moving on 1- 2 acres of land. Furthermore, the S140 weighs 468 lb without fuel, which is the S120 (444lbs), the S110 (423lbs), and S100 (415lbs). Now, the weight might create a negative notion in mind, and it won’t hamper your mowing experience. Thanks to its 48.9 inches wheelbase, you can cover a wider area every time you mow your land. 

The tractor’s cast-iron front axle and open operating system are two further aspects that add to its creativity. However, from a safety standpoint, the latter could be problematic. How? We’ll go over it in more detail in the next section (s).


However good a lawn tractor may look from the outside, it won’t thrive long if it does not come with a power-packed engine. So, John Deere, besides making their products stylish, makes sure to pack them with a promising engine. The S140 model stands true to this USP of the brand.

John Deere S140 engine

The Briggs & Stratton 44N677 (M44) engine can be found in the John Deere S140 riding lawn tractor. It has a gross power of 22 horsepower, sufficient for lawn mowing, grass tripping, snow blowing, and mulching, among other yard duties. Furthermore, because it has a tank capacity of 2.4 US gal, this product is ideal for usage on 1-2 acres of land. The tractor features V-twin cylinders and runs on gasoline. With a displacement of 724 CCs, the bore/stroke ratio is 3.12×2.89 inches. A large displacement indicates that the engine will create more energy, making the machine more efficient. However, this means that more fuel will be spent with each rotation.

The V-twin cylinder will ensure seamless operation with little stuttering, even for long periods. Furthermore, the electric start is the cherry on top, as it makes it simple to start the engine even during the coldest months of the year.

Electric Start

We’ve already discussed the benefits of this lawn tractor’s electric start. A 12V 300 CCA battery with a regulated 8 amp charging system is also included in the S140 model. Two standard incandescent headlights are also included in this variation. A higher CCA guarantees that the battery delivers more power even at cold temperatures.

Transmission & Chassis

Tuff Torq TL200 belt-driven hydrostatic gearbox is standard on the John Deere S140 model. It enables the rider to effortlessly move the tractor for mowing, cutting, and snow clearance operations. A control system with side-by-side foot pedals is also incorporated. The S140 has a top forward speed of 5.5 mph and a top reverse speed of 3.2 mph, with a turning radius of 18 inches, making it easier for the users to navigate it even in the tightest corners of the lawn.

In addition, the internal wet-disc brake allows the rider to bring the tractor to a complete and smooth stop in wet weather. So there’s no need to be worried about using this tractor during the wet season. The S140, furthermore, has a full-length 2WD welded steel frame with the CargO Mount™ system. The tractor’s molded-in color material, on the other hand, provides for quiet operation and prevents UV-induced color fading.


Safety is an essential factor to be concerned about whenever you plan to buy a new lawnmower or a tractor. We say pay special attention to this factor. That said, the S140 ensures that riders get the best quality with highly maintained safety.

This model meets the ANSI and OPEI safety standards. With the purchase, you’ll also get a safety video. Users also have access to the ‘Reverse Implement Option (RIO),’ allowing them to drive the tractor in reverse without trouble. However, unless absolutely essential, we never recommend using this feature. The ANSI also does not recommend this feature to be used at all, as doing so might cause accidents.

On the plus side, the tractor’s body is made entirely of welded steel, sturdy and durable for years to come. However, as previously indicated, one thing that could cause issues is the tractor’s open operating system. With an open working arrangement, the rider is more prone to fall off the tractor during strong jerking or turning. It also doesn’t offer any protection in the event of inclement weather.

Cut Quality

Let’s discuss the tractor’s cut quality now.

If a lawn tractor does not create a professional cut, everything comes to a halt. John Deere acknowledges this and pays careful attention to the cutting mechanisms in their products. The same can be said for the S140 model.

One of the model’s distinguishing features is the 48″ deck. Furthermore, the tractor’s V-twin engine offers sufficient lubrication to allow it to move forward without issues. On the other hand, the Edge Cutting System allows the tractor to perform multiple actions as per the needs of the users with a wide range of attachments.

Rider’s Comfort

Mowing the lawn should not be a dreaded duty for you. Hence, manufacturers increasingly focus on the rider’s comfort to make it a pleasurable experience. As a result, modern tractors feature more comfortable seating, a better control panel, and more legroom, among other features. John Deere has followed this path and included a vinyl-covered rider’s seat with a 15-inch back height. In addition, the open operator system makes it simple to get on and off the tractor. Furthermore, the tractor’s seating area is ergonomically designed, with a cup holder conveniently located.

Attachments (Optional)

John Deere S140 Attachments

Riding lawn mowers are popular for various reasons, including the fact that they may be used for more than just mowing. And it is the attachment choices that allow optional equipment to be attached to a tractor.

The S140 uses a slide under tractor attachability for locking attachments on it. Mulchers, baggers, snowblowers, grass strippers, and other accessories can be added. Its PTO engine power allows it to work with a variety of loads.

This tractor works well with the front-mounted 46″ blade and the front-mounted 44″ two-staged snowblower. The S140 also has weather protection, a sun cover, and a single bucket holder.
