Product Features
Built To Perform
Change the Oil in 30 Seconds
The John Deere Easy Change™ 30-second oil change system makes changing the engine oil as easy as twisting on a new oil-filled filter. It's simple, quick, and clean — no draining, no mess, no funnels. Every S120 comes with it standard.
Smooth Hydrostatic Drive
The Kanzaki® Tuff Torq® hydrostatic transmission offers an infinite choice of speeds — side-by-side foot pedals control speed and direction so you can maneuver with precision without shifting or lifting your foot off the platform.
Do More Than Mow
The S120 is the perfect companion for property care tasks. Use a bagger to collect clippings and leaves, transport mulch with a cart, or add a snow blower and weather enclosure for winter — every John Deere attachment is tested for compatibility.
42-in. Edge™ Mower Deck
A 42-in. stamped-steel Edge™ Mower Deck delivers a smooth, high-quality cut in a nimble footprint that gets through gates and around trees. Two high-lift blades and a deep-dome design lift grass for a clean, level cut — side discharge standard, bagger optional.

Great upgrade from my old rider!
Finally upgraded from my old 15-year-old tractor and couldn't be happier with this S120. My 3/4 acre lot with some tricky turns is no match for this machine. The 22 HP Briggs V-Twin hums along nice and smooth, and the hydrostatic transmission makes it a breeze to maneuver around the flower beds. Cuts nice and even with the 42" Edge deck. The cruise control is a nice touch for the long straightaways. Worth every penny of the investment.

Easy to use, even for me!
I'm not exactly a gearhead, but my half-acre yard here in Florida needs tending year-round. This S120 is just perfect. It starts right up every time, and the hydro drive means no fiddling with gears. The 42" deck gets done quicker than my old push mower, obviously! I even used the cruise control a few times, which is a neat feature. The warranty gives me peace of mind.

Solid Performer for Suburban Lot
Bought the S120 for my acre and a quarter in central New Jersey. Had a few concerns about the deck size for my property, but the 42" Edge covers ground efficiently. The 22 HP V-twin Briggs has plenty of power, even when the grass gets a little thick after a good rain. The two-year warranty is a comfort to have, knowing John Deere stands behind their products. Overall, a very good machine for the price.

Handles the desert heat like a champ
Moved to Arizona and needed something reliable for my new place. The S120 has been excellent for my roughly one-acre property with some slight inclines. The 22 HP Briggs V-Twin hasn't missed a beat in the summer heat, and the hydrostatic transmission is butter smooth. I appreciate the standard cruise control on the longer stretches. Maintenance is straightforward, and it's been a dependable workhorse.

Great value, reliable cutting
My old tractor finally threw in the towel, so I picked up this S120. My 0.8-acre lot never looked so good. The 42" Edge deck gives a clean, professional cut. The 22 HP Briggs motor is surprisingly quiet but powerful. This hydro drive is so much better than my old gear-driven unit. The warranty is a nice bonus and shows John Deere is confident in their product. Highly recommend for any homeowner.

Does the job for my property
While I don't have a huge ranch, my 1.5 acres here in Texas needed a serious mower. The S120 has been fantastic. That 22 HP Briggs V-Twin engine really delivers, even when tackling thicker St. Augustine grass. The hydrostatic transmission is a dream, making it easy to navigate around trees and fences. The 42" deck width gets the job done without being too cumbersome. Satisfied with this purchase.

Dependable and easy for anyone to use
With three kids and a busy schedule, I need a mower that just works. The S120 fits the bill perfectly for my 3/4 acre. The 22 HP Briggs V-Twin starts every time, and the hydro drive means even my wife can jump on and cut the grass without any fuss. The 42" Edge deck leaves a really nice, even cut. It's built tough, too. The peace of mind from the warranty is appreciated.

Comfortable and simple to operate!
I'm not as spry as I used to be, so operating a mower that's comfortable and easy is key. The S120 is wonderful for my half-acre property. The hydrostatic transmission is super smooth, no shifting needed. The 22 HP Briggs motor purrs along. The 42" deck cuts neatly, and I can even use the standard cruise control on the long stretches of my lawn. Couldn't be happier with my green machine!

Good for personal use, solid engine
I run a small landscaping business, but this S120 is just for my own 1.2-acre home. The 22 HP Briggs V-Twin engine is powerful and reliable, as I'd expect from a quality machine. The 42" Edge deck cuts well, though I usually don't use the cruise control much as I'm always turning. It's a well-built tractor for a homeowner, and the warranty length is decent.

Handles the varied terrain well
My two-acre property in Montana has some slopes and uneven spots. The S120 with its 22 HP Briggs V-Twin doesn't bog down, even in thicker sections. The hydrostatic transmission is key for navigating the varied terrain smoothly. The 42" deck makes quick work of the large areas, and the standard cruise control is handy for those long, flat runs. A very capable machine indeed.

Perfect for my suburban oasis
I've got a decent-sized lot, about an acre, and the S120 has been a dream. The 22 HP Briggs V-Twin is powerful enough for my needs, and the hydrostatic transmission makes zipping around the yard effortless. The 42" Edge deck gives a really clean finish. I appreciate the peace of mind with the John Deere warranty. It's made yard work enjoyable again!

Rugged enough for Vermont hills
Bought this for my 1.5-acre property with some gentle slopes. The S120 handles it without a hitch. That 22 HP Briggs V-Twin has plenty of power, and the hydrostatic transmission makes navigating around the trees and garden beds easy. The 42" Edge deck cuts great, even after a rainy week. Good solid machine, and I'm confident in the John Deere brand and their warranty.

Great cut, easy maintenance
My 0.75-acre yard here in North Carolina is mostly flat, and the S120 makes quick work of it. The 42" Edge deck gives a pristine cut, and the 22 HP Briggs V-Twin engine is strong and reliable. I love the hydrostatic transmission for smooth operation. Checking the oil and changing the blades is super simple. The 2-year warranty just seals the deal on a great purchase.

Does what it says on the tin
Got this S120 for my acre of mixed lawn and woods. The 22 HP Briggs V-Twin handles the damp Pacific Northwest grass without scalping, which is impressive. The 42" Edge deck gives a clean look. The hydro transmission is smooth, though I don't use the cruise control too often due to all the obstacles. It's a solid, dependable mower for the price and the warranty is a bonus.

I grew up on a farm, so I appreciate a good piece of machinery. This S120 is for my 2-acre suburban lot now. The 22 HP Briggs V-Twin never struggles, and the 42" Edge deck makes quick work of things. The hydrostatic transmission is so much easier than shifting. I use the standard cruise control on the long straightaways. This will last me a long time. Great warranty.

Handles altitude and slopes with ease
My 1.5 acre property has some decent slopes and we're at a higher elevation. The S120's 22 HP Briggs V-Twin engine has never felt underpowered. The hydrostatic transmission is excellent for maintaining control on the inclines. The 42" Edge deck provides a consistently good cut. I’m impressed with its durability, even after two seasons of use. John Deere quality shines through.

Easy start, smooth ride
Cutting grass in Louisiana is a year-round affair! The S120 has been a lifesaver for my 1-acre yard. That 22 HP Briggs V-Twin engine starts instantly every time, which is a blessing. The hydrostatic transmission is incredibly smooth, making it easy to navigate around my many live oaks. The 42" deck cuts evenly, even when the grass is thick. Very happy with this purchase and the included warranty.

Wife-approved mower!
My husband picked this out for our 0.9-acre lot, and I actually enjoy mowing now! The S120 is so easy to drive, thanks to the hydrostatic transmission. The 22 HP Briggs V-Twin engine isn't too loud, and the 42" Edge deck gives a beautiful finish. I even use the standard cruise control when I'm on the bigger sections. It feels very safe and intuitive. Great machine!

Reliable for New England seasons
Got the S120 for my 1.3-acre property with some dense grass. The 22 HP Briggs V-Twin engine has plenty of grunt, and the 42" Edge deck handles it well. I've even attached a small cart in the fall for hauling leaves. The hydrostatic transmission is a game-changer compared to my old manual. The standard cruise control is a nice convenience. Solid tractor for northern use.

Nothing runs like a Deere
20 HP V-Twin has plenty of power for my property. The Easy Change oil system saved me a trip to the dealer and a mess in the garage. Highly recommend.

Extremely quiet and smooth
Compared to my old Craftsman, the S120 feels like a Cadillac. Very quiet muffler, smooth pedals, comfortable seat. I can mow for hours without feeling beat up.

Reliable after a full season
First full season with the S120 and no issues. Regular maintenance is a breeze. The 42" deck fits perfectly through my gates and the hydrostatic drive is butter smooth.

Cut quality is the reason I'd buy it again
Third season on the S120 and the finish is still dealership quality. Even in thick spring growth it lays the grass over cleanly in one pass instead of leaving stragglers I have to go back over.

Arrived fully assembled and ready
Freight truck dropped the S120 on a liftgate, fully assembled with oil and battery in place. I read the manual, checked tire pressure, and was mowing the same afternoon.

Starts on the first turn, every time
Cold mornings, hot afternoons, sitting three weeks between mows — the S120 fires right up. No surging, no stalling when I drop into taller grass.

Comfortable enough for a two-hour mow
The seat and control layout on the S120 are genuinely well designed. I do about two hours at a stretch and get off without a sore back, which was never true of my old machine.

Better value than the box-store brands
I shopped the orange and red brands first. For the build quality and warranty, the S120 was the easy call — and Deere resale value is in a completely different league when you go to sell.

Handles my slopes without drama
Property has a couple of moderate grades. Taking them across the face, the S120 stays planted and predictable. Never felt like it wanted to slide on me.

Maintenance is homeowner friendly
Oil, filter, blades and grease points on the S120 are all easy to reach. No pulling half the machine apart to do a routine service like some of the competition.
