• John Deere Easy Change™ 30-second oil change system

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.
• 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 John Deere 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.

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.

Please recycle. Many local government recycling programs, authorized retailers, auto-service centers, and auto-parts stores will puncture and recycle used oil filters and oil.
