Check your owner’s manual for specific end-of-season or storage procedures. This show will primarily focus on fuel. This guide applies to all small engines including tractors, mowers, string trimmers, chain saws, blowers, etc.
The Deere owners manual states:
IMPORTANT: Avoid damage! Stale fuel can produce varnish and plug carburetor or injector components and affect engine performance.
This issues is compounded by a fuel additive called Ethanol. The Ethanol can attract moisture which contributes to the issues. If possible use non-ethanol fuel in your small engines but still follow these procedures.
The end of season procedures are different if you have been adding Fuel Stabilizer to your fuel or not.
If you have been using “Stabilized Fuel”:
- Add stabilized fuel to tank until the tank is full.
- NOTE: Filling the fuel tank reduces the amount of air in the fuel tank and helps reduce deterioration of fuel.
If you are not using “Stabilized Fuel”:
1. Park machine safely in a well-ventilated area.
NOTE: Try to anticipate the last time the machine will be used for the season so very little fuel is left in the fuel tank.
2. Start the engine and allow to run until it runs out of fuel.
3. Turn off the key
