Clean and stow your lawn mower
1. Add Fuel Stabilizer to gas tank and run the mower for 5 minutes to make sure the stabilizer gets to the carburetor. Or, if your mower has a fuel shut off then shut it off and let it run until it stops
2. When the mower is cool, remove the spark plug and pour a capful of engine oil into the spark plug hole.
3. Pull the starter cord a couple of times to distribute the oil, which keeps pistons lubricated and ensures an easy start come spring.
4. Turn the mower on its side and clean out accumulated grass and gunk from the mower deck.
Drain your sprinkler system
Time to drain your irrigation system. Even buried irrigation lines can freeze, leading to busted pipes and broken sprinkler heads.
Turn off the water to the system at the main valve.
Shut off the automatic controller.
Open drain valves to remove water from the system.
Remove any above-ground sprinkler heads and shake the water out of them, then replace.
If you don’t have drain valves, then hire an irrigation pro to blow out the systems pipes with compressed air. A pro is worth the $75 to $150 charge to make sure the job is done right, and to ensure you don’t have busted pipes and sprinkler head repairs to make in the spring.
