Steps
Park the tractor on a level surface in a well-ventilated spot, such as a garage or shed, and let the engine cool before you start.
Check the fuel level. A fuller tank leaves less room for air and moisture, so top up with fresh gasoline if needed.
Read the stabilizer label and add the dose it states for the amount of fuel in your tank. Do not guess the ratio.
Start the engine and let it run for a few minutes so the treated fuel circulates through the carburetor and fuel lines.
Shut off the engine and the fuel valve if your model has one.
Connect the battery maintainer's leads to the battery, red to positive and black to negative, with the unit unplugged.
Plug in the automatic maintainer and check that its indicator shows it is charging or maintaining.
Leave the maintainer connected for the whole storage period and check the battery terminals for corrosion now and then.
Tips and common mistakes
Use an automatic maintainer, not a basic charger, so the battery is not overcharged during months of storage.
Add stabilizer before the last mowing of the season and run the engine so treated fuel reaches the whole system.
Store the mower with the battery maintainer in a dry place and keep cords clear of walkways.
Remove the battery and store it indoors if you have no power in your shed.
Questions
Do I need to remove the battery to use a maintainer?
No. You can leave the battery in the tractor and connect the maintainer leads directly to the terminals. Just keep the unit dry and the cords out of the way.
Can I use a solar maintainer instead?
Yes, a small solar maintainer works if the mower sits somewhere with daylight. It keeps a charged battery topped up but will not revive a battery that is already flat.
Does this work on other riding mowers?
Yes. The same two steps apply to most riding mowers, including other John Deere X300 series models. Check your owner's manual for any model-specific storage advice.
