• 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

• 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 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 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.

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

• Everyone who uses the John Deere Easy Change system saves time and avoids the mess of a traditional oil change. In the past, many 100 Series Lawn Tractor owners rarely or never got around to changing their engine oil. With the 30-second oil change, even people who previously would not consider changing the oil themselves can easily do it. The Easy Change system is a no-mess, no-fuss solution the competition cannot match.

• Installation instructions are in the Operator’s Manual and in the John Deere Easy Change service part box.

• This full-featured engine is engineered to deliver world-class endurance and power.
