2021 John Deere S120

Features may include:

A 20-hp (14.9-kW) V-twin engine has plenty of power and torque to handle tough mowing, mulching, and bagging conditions:

• V-twin cylinder design for greater torque, lower vibration, and improved sound quality

• Auto choke to allow operators to start the engine without needing the choke unless air temperatures are near or below freezing

• Spring-return feature to ensure the operator will not mistakenly leave the throttle lever in the choke position

• Electronic ignition for fast starts

• Cast-iron cylinder liners for longer engine life

• Overhead valves for excellent power and fuel economy

• Full-pressure lubrication and oil filter for cleaner oil, prolonging engine life and extending the time between oil changes

• More effective when operating the tractor on an incline

• John Deere Easy Change™ 30-second oil change system makes changing the engine oil easy, quick, and clean.

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

Fuel tank:

• The capacity is 2.4 U.S. gal. (9.1 L).

• The fuel-filler opening is conveniently located under the seat.

• Filling the tank without spilling is easy.

• A tethered fuel tank cap is more convenient.

• The sealed fuel cap helps keep vapors inside the tank.

• The tractor has a California Air Resources Board (CARB) certified engine for reduced air pollution.

The John Deere Easy Change 30-second oil change system makes changing the engine oil easy, quick, and clean. Changing the oil is as easy as twisting on a new oil-filled filter. Oil does not need to be drained from the engine.

The John Deere Easy Change filter is an additional engine oil reservoir. Changing the filter removes the captured contaminants and replaces about 0.8 qt (0.76 L) of the engine oil.

The functionality does not stop with ease of use. The Easy Change oil system has several meaningful benefits over the traditional oil filter system of the 100 Series:

• A synthetic filter material is used for more predictable filtering and longer life.

• Filtering capacity is greater than with a standard oil filter.

• More filter surface area

• More oil flow capacity

• The system has 40 percent more oil volume.

• The oil and engine run cooler.

• The oil filter valve closes whenever the engine stops, so filtered particles are captured and cannot drain back into the engine.

• The risk of spilling during oil service is greatly reduced.

• Waste oil (and new oil production) is reduced by over 1,000,000 lb (453,592.4 kg) per tractor production year.

• This system is not a compromise to just make oil changes easier—these engines pass the same expectations and rigorous testing as always.

Partly due to these improvements, it is not necessary to remove and dispose of all the oil in the engine during service.
