Features of John Deere S120
We hope you have taken a look at the table above and got a rough idea about S120. Now, let’s dig deeper to unfurl things better.
First, we will focus on the general specifications of this lawnmower cum tractor to give you an idea of how it will get accommodated in your yard. Not all tractors or mowers are suitable for every yard. One must choose a mower based on the yard’s size, type, grass thickness, etc.
Hence, to help you out, here is a detailed analysis of the features.
1. Physical Specs
Like any other John Deere product, the first thing to notice in S120 is its color-coding. The brand has kept its official green and yellow color coding for this lawn tractor. And it is through this body color you can pinpoint the product, among others.
After noticing the product by its color, you will immediately get glued to it by its sleek look. This tractor has a dimension of 69.7″ x 55.2″ x 44″ (l x w x h), which is perfect for mowing 1- 2 acres of land. When not in use, you can also store this machine in a smaller place, such as a garage or garden shed. The S120 weighs 444lbs, which is slightly higher than the S110 (423lbs) and S100 (415lbs). Still, this weight won’t bother you operating it.
Some of the other features to look at are its cast-iron front axel, which offers it a robust build meant to last for years. Also, the rider will get an open operator station, which makes it easy to hop on the tractor. Unfortunately, however, this facility does not provide any protection from bad weather and an accident.
A mower might look very attractive outwards but lacks a powerful engine. It won’t serve its purpose in such a situation, and only a great look can’t save it. Hence, based on your mowing needs, you must inspect the engine of the lawn tractor or mower before saying yes to it.
That said, the S120 is equipped with a Briggs & Stratton 44N677 engine. It has a gross power of 22 horsepower, which is more than sufficient for mowing a modest to medium-sized lawn. The tractor is fueled by gasoline and has V-twin cylinders. The bore/stroke ratio is 3.12×2.89 inches, and the displacement is 44.2 cubic inches.
The V-twin cylinder will provide smooth running with minimal jerking even when operated for extended periods. Unfortunately, the S120’s gasoline tank is positioned in the back and has a capacity of 9.1 liters, which is extremely low. On the plus side, the S120 boasts an electric start that enables starting the engine even in sub-zero temperatures much easier.
3. Electric Start
For all lawnmowers, the electric start technology is a godsend, especially if you live in a location with harsh winters. With an electric engine starter, you can ignite the tractor’s engine even at a sub-zero temperature with the flip of a switch.
Keeping this convenience in mind, John Deere has provided the S120 model with a Benedix-type starter with a regulated 8 amp charging system. This variant includes a 12 V 300 CCA battery as well as two incandescent standards headlights. Even at low temperatures, a greater CCA ensures that the battery produces more power.

4. Transmission & Chassis
The S120 comes with Tuff-Torq TL200 belt-driven hydrostatic transmission. This transmission allows the rider to easily maneuver the tractor for mowing, chopping, and snow-blowing tasks. A side-by-side foot pedal control system is also included. The S120 can travel at a peak forward speed of 8.8 km/h and a peak reverse speed of 5.1 km/h.
On the other hand, the internal wet-disc brake allows the rider to bring the tractor to a complete and smooth stop in wet weather. However, riders are advised not to use the oil change because the area is sealed. With the standard cruise control technology, you can now concentrate on mowing because the pace will remain constant regardless of the terrain.
A full-length welded steel frame and a 2WD chassis are also included with the S120. The tractor’s welded steel frame keeps it rust-free and corrosion-free for a long time. The tractor’s color coat, on the other hand, prevents any color fading caused by UV radiation. Apart from this, the CargO Mount™ system is the icing on the cake.
Our decision to buy a machine depends on two things; first, we look for safety standards, and the second is, a warranty. It is not at all recommended to go for a product that does not label the safety standards it has adhered to. However, this is not the case for John Deere S120.
The ANSI and OPEI safety requirements are met by this riding lawn tractor. A safety video is also included. In addition, the ‘Reverse Implement Option (RIO)’ allows the rider to drive the tractor in reverse without difficulty. That being stated, we never recommend mowing in reverse unless it is the only option left.
The tractor’s entirely welded steel body is also a plus for the buyer. However, one factor could cause problems: the tractor’s open operating system. It is both a blessing and a bane for the S120 and various other John Deere models. In severe jerking or turnover, the rider is more likely to fall off the tractor with an open working system. It also does not protect in the event of bad weather.
6. Cut Quality
When purchasing a lawn tractor, you want a machine that can make high-quality cuts that leave your grass looking clean, crisp, and manicured. The 42-inch cutting deck is one of the most appealing characteristics of this machine in this regard. In addition, the tractor’s V-twin engine provides adequate lubrication to allow it to go forward smoothly.
The S120’s Edge Cutting System enables it to function as a mower, mulcher, plus bagger. As a result, you’ll be able to clip thorny lawn edges consistently every time. On the other hand, the side-discharge option helps to move the clippings side-by-side, while the 18″ turning radius allows you to make excellent turns even in narrow spaces.
7. Rider’s Comfort
A tractor that does its work well but is a pain in the rider’s back is never a good thing. Hence, John Deere ensures that its products are built with the rider’s comfort in mind.
That being said, the S120 has an open operator’s cabin, allowing the rider to board the vehicle quickly. It also includes a 15-inch backrest that helps the user support their back when working in the field. In addition, the tractor’s seating area has been ergonomically built, with a cup holder within easy reach. The S120 also comes with dirt-removal grooves in the floor mats.
8. Attachments (Optional)
A riding tractor is not just for mowing grass. These machines are meant to serve multiple purposes, including grass stripping, snow blowing, etc. So, the S120 is made with this need in mind. In addition, with this lawn tractor, you will get a range of attachment options.
The John Deere S120 utilizes a slide under tractor attachability for latching attachments. Furthermore, the PTO allows the user to mount multiple attachments based on the users’ needs. The front blade, mulcher, rear bagger, and snowblower are some of the most important attachments that can be utilized with the S120.
The front-mounted 46″ blade is excellent for this tractor, while the front-mounted 44″ two-staged snow blower can be used with it. A weather guard, a sun cover, and a single bucket holder are all included with the S120.
