Two long seat springs give plenty of seat travel to smooth out the ride, keeping the operator comfortable while operating the tractor.
The seat can be tilted forward for protection from the elements and to provide easy access to the fuel tank.
Storage compartment and beverage holder, located on the right-side fender, are conveniently located and easy to use.
NOTE: A storage compartment cover is standard on S120, S130, S160, S170, and S180 Tractors and optional on the S100, S110, and S140.
Fender flares included on the S130 Tractor cover the tires more completely and add style to the tractor.

Increments of 1/4 in. (0.64 cm) allow fine-tuning the cut height.
-
Cut height is adjustable from 1 to 4 in. (2.5 to 10.2 cm).
-
The lift handle is shaped for easy use and is out of the way of entering or exiting operators.
Parking brake control

Electric power take-off (PTO) clutch is easy and convenient
The heavy-duty electric PTO clutch is operated with a convenient dash-mounted switch.
Reverse implement option (RIO)
Using RIO
CAUTION: Children or bystanders may be injured by rotating blades. Before traveling forward or rearward:
- Carefully check the area around the machine.
- Disengage the mower before backing up.
NOTE: Backing up while the mower is engaged is strongly discouraged. RIO should be used only when operating another attachment or when the operator deems it necessary to reposition the machine with the mower engaged.
- Stop forward travel.
- Look behind the machine to be sure there are no bystanders.
- Push and hold in the RIO switch while depressing the reverse pedal slightly for a hydrostatic transmission or moving the transmission shift lever to the rear slot (reverse) for a continuously variable transmission (CVT)/automatic transmission.
NOTE: If the engine and mower or other attachment stops while repositioning the machine, return the attachment engagement lever/switch to the off position. Start the engine and engage mower or other attachment. Begin again with step 2.
- Release the RIO switch and reposition the machine as the machine begins to move rearward.
- Resume forward travel. The mower or other attachment should continue operating.
- Repeat procedure to position the machine again.
Fuel tank gauge shows fuel level from the operator's seat
The fuel tank gauge shows how much fuel is in the tank and can be seen without leaving the operator's seat:
- Easy to check fuel level
- Convenient location
The one-piece hood opens easily to permit checking and servicing the engine:
- Important service points are located within easy reach.
- A service interval decal is provided inside the tractor hood for convenience when servicing the tractor.
The engine fuel and oil filters, the oil check/fill tube, and the oil drain tube are exposed for serviceability when the hood is opened.
The seat tilts up and out of the way to make adding fuel easy.
Quick response (QR) codes link to owner information web pages
John Deere riding lawn mowers are supported by owner information web pages that include links to:
- Safety and how-to videos
- Operator’s manuals
- Parts catalog
- Maintenance reminder sheets
- Attachments
- Warranty registration
To speed access to owner information web pages, a QR code is printed onto a PIN label located near the fuel fill.

Purchased this mower 2021 summer. Nice to look at but the bolts shear off after several mowing, destroying the bolts and belt which is costly to repair and leaves you with out a mower weeks at a time! Third time for it to be repaired.

I bought this John Deere S-140 mower at the start of mowing season 2022. My satisfaction is tempered by the 20 inch tires. Coming off of a 2014 TroyBilt Super Bronco XP 50 that had the larger wheels, I find more difficulty in getting across above ground tree roots and rough terrain. I also dislike the left handed lift for the deck. The spring assist isn't as much help as I needed with my arthritic shoulder so I added 2 rubber straps to help out. It's a Lawn Mower not a garden tractor and does a fine job mowing with plenty of power.

I've used this mower for my rough and hilly 3 acres for 6 yrs. Other than seasonal maintenance, the plastic steering bushings and recently, the spindle bearings are all that have been replaced. The motor doesn't smoke or use oil after 480 hrs. I keep it under a lawn mower port; the tires and seat still look good. It uses a gallon per hour of mowing. The mower belt needs replacing annually, (60 hrs) and the drive belt semiannually. At 5 years the John Deere dealership replaced the steering bushings. They said that was timely as other problems may have developed if I had waited. This year 2 mower belts came apart. Discovered the spindles were worn out which allowed the belt to rub against the mower platform supports. I could run it for years more but 3 acres deserves a John Deere zero turn.

I used to be able to mow the incline on my front lawn the first year. Second year it could no longer had the power to go up the hill. I find it totally annoying that the John Deere operators manual does not have the words, muffler or exhaust. Would have been nice had John Deere chose to put a link for the manual along with description of the product.

I got this mower last year. Deck belt came off 3 times. Now it's broken. Mower has good power just will not cut grass well. Little tires lose traction and spin tearing up the yard on hills.
