John Deere E120 vs S120 Lawn Tractor Comparison [2025 Guide]

Choosing between two of John Deere’s most popular 100 Series lawn tractors, the E120 and S120, isn’t easy. Both offer plenty of power with 22 HP V-Twin engines, comfortable rides, and practical features for homeowners who want reliable performance. Shoppers who want the best fit for their yard care routine will need to weigh the differences in build, deck options, comfort, and long-term value. A smart comparison helps you invest in a tractor that works with your property size, budget, and expectations for durability.

Overview of the John Deere E120 and S120 Lawn Tractors

When you look at John Deere’s 100 Series, the E120 and S120 stand out for homeowners who want solid power, user-friendly features, and long-term dependability. Both fit into the lineup as practical choices, but each brings its own story in terms of launch, customer focus, and the type of value you get.

Place in the John Deere 100 Series

The 100 Series has earned a reputation as the backbone of John Deere’s residential tractors. It’s designed for regular yard work, larger lawns, and users who want equipment that feels both approachable and reliable. The E120 and S120 are two popular models in this series that provide just the right mix of performance and comfort.

• The E120 entered the market as a highly accessible, easy-to-run tractor focused on families with medium to large suburban lawns. Its introduction brought newer features like the Easy Change™ 30-Second Oil Change System and a comfortable high-back seat.
• The S120 came out a few years later as part of a refreshed 100 Series lineup. It’s seen as an evolution of the E120, boosting engine power and modernizing controls while keeping the best-loved features from previous models.

Both tractors hold a middle ground within the 100 Series, sitting above the entry-level models but staying more affordable and less complex than John Deere’s premium X Series. If you want a practical workhorse with a recognizable green-and-yellow finish, these models set a strong standard.

E120: Launch Period, Market Position, and Target Customer

Launched around 2018, the E120 was aimed at homeowners wanting a simple but capable solution for cutting grass, hauling garden supplies, and other routine tasks. The goal was to deliver strong value, easy maintenance, and user-friendly controls.

Key features that made the E120 popular:

• A 20 HP V-Twin engine known for smooth operation.
• The Edge™ mower deck cut system for a reliable mow.
• Effortless hydrostatic transmission—just press and go.
• The innovative 30-second oil-change system.

The E120’s launch signaled John Deere’s intention to make yard care less intimidating and more approachable. It became a natural choice for families and new property owners stepping up from walk-behind mowers. For detailed specs and a closer look at what the E120 offers, see John Deere’s Canadian E120 product page.

S120: Launch Period, Market Position, and Target Customer

The S120 arrived with the next wave of 100 Series improvements, offering a step up in engine strength and control feel. This model suits buyers looking for extra muscle and a more modern operator experience but still wanting a strong value proposition.

Why shoppers pick the S120:

• Upgraded 22 HP V-Twin engine for increased power.
• 42-inch mower deck that handles tough, thick grass.
• Same convenient oil-change system as the E120.
• Upgraded high-back seat and side-by-side pedal layout for comfort.

The S120 quickly established itself as a go-to for anyone who needed more cutting power for bigger yards or rougher terrain. This model appeals to homeowners who mow large areas, maintain multiple properties, or expect a little more “oomph” from their tractor. For a detailed breakdown of customer reviews and the S120’s current features, check out the John Deere S120 product page.

Both the E120 and S120 reflect John Deere’s goal to balance comfort, performance, and affordability—making them ideal choices for anyone who wants a trusted name and proven results in the yard.

Engine Performance and Mechanical Differences

When comparing the John Deere E120 and S120, the heart of the matter comes down to what’s under the hood, how that power reaches the wheels, and how each tractor handles grass cutting. Small differences here have a big impact on your mowing experience. Let’s dig into the horsepower, transmission types, and deck performance of each to help you decide which option best fits your lawn and style.

Horsepower and Engine Specifications

The John Deere E120 features a 20 HP V-Twin Briggs & Stratton engine, known for its reliable starts and smooth operation. It offers enough muscle for average-sized lawns, mulching, and hauling light yard loads. You get a fuel-efficient ride that keeps routine maintenance simple for the everyday homeowner. The V-Twin configuration helps reduce vibration and improves engine life. Specs show it runs at a comfortable RPM and doesn’t struggle when tackling thicker patches of grass (learn more about the E120’s engine details).

In contrast, the S120 steps up with a 22 HP V-Twin engine. This boost of 2 additional horsepower delivers extra push for larger or more challenging yards where stubborn weeds or wet grass might slow down a lower-powered tractor. If you mow a big property, handle uneven turf, or often run with a bagging system attached, this extra power level is a winning advantage (see the 22 HP S120 engine specs).

Key points at a glance:

• E120: 20 HP V-Twin, great for moderate lawn sizes and everyday mowing tasks.
• S120: 22 HP V-Twin, extra power for tougher, larger yards or frequent heavy use.

Transmission and Drive System

The transmission plays a key role in how easy a lawn tractor is to drive and maneuver. The E120 uses a hydrostatic transmission, which allows you to control speed and direction simply by pressing pedals—no gear shifts or clutch to worry about. This lets you smoothly adjust speed and easily reverse without stopping, which is perfect for mowing around trees, flower beds, or fences (see more about the E120’s hydrostatic system).

The S120 also features a hydrostatic transmission, but with updated controls. The foot pedals are laid out side-by-side, much like a car, and give you better feel and quicker adjustments. These improvements make stop-and-go mowing, parking, and tight turns easier for users who want a modern driving experience (details on S120 hydro transmission).

What this means for you:

• Both tractors offer no-shift, pedal-driven operation for simplicity.
• The S120’s updated feet-forward pedal controls provide more intuitive use and less fatigue, especially over long mowing sessions.

Deck Design and Cutting Performance

John Deere makes a point to keep mowing results consistent within the 100 Series. Both the E120 and S120 come equipped with a 42-inch Edge™ cutting deck, offering a good balance between wide mowing paths and easy maneuverability in tighter spaces. This width suits most residential lawns and reduces the need for endless lap-after-lap mowing.

The deck design on both includes:

• Two-blade system for an even cut
• Adjustable cutting heights for custom lawn looks
• Compatibility with baggers and mulch kits so you can tailor the mow to your preference

The real difference shows up in the quality of cut when power is needed. The S120’s extra engine output lets you mow thicker grass at a steady pace without bogging down and handles accessory attachments more confidently. Both decks are made of heavy-duty stamped steel for durability, so you can expect years of reliable use (and if you want more technical details, check the Home Depot product listing for the E120).

Advantages of the 42-inch decks:

• Cover more ground each pass for faster mowing times
• Smooth, professional-looking results on flat or rolling lawns
• Simple maintenance and strong resistance to rust with regular cleaning

For most homeowners, either tractor delivers a crisp, dependable cut that John Deere is known for. The choice depends on how much yard you cover and the conditions you’re working in. The S120 will win out for those who value top-tier power, while the E120 remains a steady performer at a more budget-friendly entry point.

User Experience and Comfort Features

A riding lawn tractor isn’t just about deck size or horsepower—the real test is how it feels in action. John Deere’s E120 and S120 both raise the bar for convenience and comfort, keeping the operator front and center. From the way you sit and control the machine, to how easy service tasks are, and even how safe you feel as you mow, these tractors stand out in the residential field.

Operator Station and Ergonomics

Day-to-day mowing is much easier when a tractor doesn’t fight you. Both models offer an open, spacious operator station so you won’t feel hemmed in, even if you’re tall or need room to move.

• Seats: The E120 and S120 sport high-back, medium-firm seats with built-in suspension. They give solid lower back support so you don’t feel every bump, and padding that doesn’t flatten out after an hour.
• Control Layout: Everything is close at hand. The S120 edges ahead here with side-by-side pedals for forward and reverse—just like driving a car. This familiar setup means fewer missed shifts or jolts.
• Steering: Both models have a comfortable steering wheel with a soft grip, wide enough for steady handling but not bulky. Turning remains light, even with a full gas tank or when going around tight landscaping.

Maintenance Ease and Serviceability

No one enjoys getting stuck in the garage with a list of maintenance chores. That’s why easy service features matter. John Deere hit the mark by designing both tractors with the Easy Change™ 30-Second Oil Change System. You simply twist on a new cartridge—no tools, no mess, no crawling under the engine.

• Quick Service Access: The hood lifts smoothly for filter checks, oil refills, and spark plug changes. With most key points on top or the side, reaching what you need is simple.
• Routine Care: Grease points and checkpoints are mapped out and labeled, so it’s easy to keep up with recommended service without guessing what to do first.

Safety and Convenience Enhancements

Keeping the user safe and stress-free is a top priority. Both tractors come with built-in safety switches, including the Reverse Implement Option so you can mow in reverse only when you mean to. The parking brake lever sits right at your side, giving you clear confirmation it’s engaged.

You’ll also find:

• Fuel Gauge: The S120 features an easy-read dashboard fuel gauge so you know how much is left at a glance, helping avoid unexpected stops (S120 fuel gauge feature).
• Lighting: Bright headlights let you see clearly for evening or early-morning tasks.
• Digital Compatibility: The S120 pairs with John Deere’s MowerPlus™ app (via optional connector), offering maintenance tracking and mowing stats right on your phone.

In practice, these features add up. You get not just a comfortable ride and easy upkeep, but also smart tools to keep you safe and informed as you tackle your yard.

Attachment Compatibility and Versatility

Having the right attachments for your lawn tractor gives you control and flexibility over yard work year-round. Both the John Deere E120 and S120 shine when it comes to handling a range of add-ons. Let’s look at how each model fits with baggers, mulching kits, mower decks, and other gear you might want for mowing, hauling, or even snow removal.

Mower, Collection, and Mulching Options

John Deere makes it simple to expand what your mower can do. Both the E120 and S120 are built to match the same family of attachments, which means switching out between bagging, mulching, or side discharge is quick.

Here’s what you can attach to each:

• 42″ Mower Decks: Both tractors use the 42-inch Edge™ deck system, so you don’t need a new deck if upgrading between models. The deck is rugged, rust-resistant, and easy to maintain.
• Rear Baggers: Add a rear bagger to collect clippings. John Deere’s 6.5-bushel bagger fits both models, picking up grass, leaves, and even light yard debris. This is especially helpful in fall or when you want a clean, finished look.
• Mulching Kits: If you prefer to return clippings right to the lawn, both models accept plug-and-play mulching kits. These kits chop grass finely, promoting lawn health and saving cleanup time.
• Deck Clean-Out: Both tractors support the use of deck wash ports, making it easier to clear grass after mowing so your deck lasts longer.

For a complete list of compatible baggers, mulching kits, and mower deck options, check John Deere’s official Riding Mower Attachments & Accessories page.

Additional Attachments and Accessories

A John Deere lawn tractor isn’t just for mowing—think of it as the base for a year-round yard care toolkit. The E120 and S120 unlock more options when the seasons change.

Some popular add-ons include:

• Snow Removal: Both tractors handle front blade attachments for clearing light snow in winter. A compatible snow blower add-on makes short work of heavier drifts, so you stay ahead of storms.
• Carts and Hauling: Tow-behind carts are a staple for moving mulch, rocks, firewood, or garden gear. You can also add broadcast spreaders or sprayers for fertilizing and seeding.
• Lawn Care Implements: Attach aerators, dethatchers, and sweepers to boost lawn health and save labor during spring and fall cleanup.
• Weights and Tire Chains: For added traction and stability in mud, snow, or uneven terrain, both models can take rear wheel weights and tire chains without issue.

Want to double-check gear compatibility? John Deere offers an Implement Compatibility Tool to match your exact tractor and accessory list.

Both the E120 and S120 prove themselves as versatile machines. They work just as hard in summer cutting grass as they do in winter moving snow, or during any other season hauling, raking, or caring for your property. That level of compatibility is a big part of what sets John Deere’s 100 Series apart for homeowners who want one tractor that does it all.

Reliability, Customer Feedback, and Value

When you compare the John Deere E120 and S120, it’s not just about specs on paper. Lifespan, real-world performance, and the value you get over years of use matter just as much. Owners want a mower that starts every time, runs smoothly, and keeps its edge from spring to fall. This section covers reliability, what customers report after many hours in the seat, and how each tractor holds its worth down the road.

Durability, Warranty, and Long-Term Ownership

John Deere designs both the E120 and S120 with reliability in mind. Their frames are built from heavy steel and finished with a tough powder coat, so scrapes and the daily bumps from yardwork don’t easily wear them down. Both tractors feature the company’s signature yellow seat and green body, known to withstand years of sun and rain.

• Warranty: The S120 is covered by a 2-year/120-hour bumper-to-bumper warranty, reflecting John Deere’s promise of long-lasting performance. Most dealers extend similar coverage to the E120, giving buyers confidence when issues pop up in the first seasons of use.
• Common Points of Wear: Like any lawn tractor, certain parts require attention over time. Owners often replace:
  • Drive belts: Regular inspection helps avoid unexpected downtime.
  • Tires: After several seasons, tread wear is normal, especially if used on rough terrain.
  • Battery and electrical: Batteries may need replacing every few years, and connections should be checked each spring.
• Frame and Deck: Reports show the deck resists rust when cleaned regularly, and the frame stands up well unless the tractor faces repeated heavy-duty use beyond normal mowing.

Consumer Reviews and Performance Reports

What matters most is what real owners are saying after putting hundreds of hours on these machines. Looking at broad customer feedback:

• John Deere E120: Users appreciate the solid cut, simple maintenance, and fuel-efficient engine. Many praise it as a step up from entry-level models, with enough comfort for longer sessions. Some owners mention the mower deck can clog if wet grass piles up or if clippings aren’t regularly cleared, which is a common issue in this class.
• John Deere S120: The S120 frequently gets high marks for its extra engine power, smoother pedal layout, and quiet running. Customers highlight the tight turning radius and find that its upgraded seat and controls reduce fatigue over time. Negative feedback sometimes points to pricing and the need for careful maintenance on electrical connections to avoid minor start issues.

You can read firsthand owner reviews and see detailed performance comments for the S120 on e-marketing.deere.com’s S120 user ratings and Home Depot’s S120 customer feedback page.

Longtime John Deere buyers, both new and returning, often say these tractors outperform similarly priced competitors over several years, though a few note you do pay more for the recognizable brand and dealer support (see user experiences comparing John Deere vs. budget alternatives).

Pricing, Dealer Support, and Resale Value

The E120 and S120 sit at different price points depending on the season and region. The S120 typically costs a few hundred dollars more, reflecting its stronger engine and refined controls.

• Average Pricing: The S120’s extra features push it to the higher end of the 100 Series. On the used market, both hold their value well, but the S120 tends to fetch a better resale price thanks to its newer design.
• Dealer Support: Buyers consistently praise John Deere dealerships for setup, delivery, and knowledgeable service techs. Many locations offer first-year checks or bundled maintenance programs, making that “green tractor” investment less stressful. Genuine parts and quick repairs help keep downtime to a minimum.
• Value Retention: Both models enjoy strong brand loyalty, and John Deere’s reputation for durability means they often trade for more than most rivals after several years. For those eyeing eventual resale, using a dealer valuation tool can give you an estimate before listing. Selling independently may return even more, as explained in this overview on maximizing mower trade-in value.

With either the E120 or S120, buyers get a reliable tractor, time-tested customer support, and a good shot at getting money back when it’s time to upgrade. Regular upkeep and clean storage stretch that value further, whether you’re passing it down or selling later.

Conclusion

For most homeowners, the S120 stands out as the stronger choice for bigger yards, tougher mowing jobs, and those who value smoother handling with its upgraded engine and easy-to-use controls. Its 22 HP V-Twin engine and side-by-side pedals mean less work for you and more consistent performance, even if you have hills or thicker grass.

If your focus is a reliable upgrade for a medium suburban property and you don’t need the extra muscle, the E120 remains a dependable ride. It brings you John Deere quality and service without pushing your budget.

Both models offer comfort and plenty of flexibility with attachments, backed by positive owner feedback and solid resale value. Whichever you pick, consistent upkeep goes a long way in protecting your investment. If you’ve narrowed your options, visit your local John Deere dealer and see which fit feels right in the seat.
