Eight Great Tips to Prepare Your Lawnmower for Summer

Summer’s here. Is your lawnmower ready?

Summertime is all but here. Is your lawnmower ready? E3 Spark Plugs has a few tips to help make sure you’re in the running for that Lawn of the Month plaque.

  1. Replace your fuel: Lawnmower fuel can go bad in just 30 days. So, by the time it sits all winter long, it can turn to muck, causing your mower’s engine to sputter or even prevent it from turning over. Before your first mow of the season, drain the old fuel and fill up with fresh gasoline.
  2. Oil up: Grease and oil left over from the previous season can harden, making your mower’s moving parts not want to move. Loosen things up by applying a light lubricant on spots like the throttle spring and the height adjustment lever.
  3. Clean or replace the air filter: Dirt, debris and oil can clog up your lawnmower’s air filter over the course of a mowing season, blocking oxygen from entering the engine. That’s why mower starts to sputter like it’s having a coughing spell. Clean a washable filter or replace a disposable one before you fire up your mower for the new season.
  4. Check the oil: Like gasoline, your lawnmower’s motor oil can muck up after sitting for months. Change it before your first mow of the season, then check and top it off after every five to eight hours of mowing time to keep from burning out the engine.
  5. Check the battery: Chances are your electric-start lawnmower’s battery could use a fresh charge after a long winter. Check your mower owner’s manual for the best way to go about a recharge or replace it if it’s been a few years.
  6. Check the belt: Before your first seasonal mow, check your lawnmower’s belt for signs of cracking and wear and, if you spot them, replace the belt immediately. Throughout the season, be sure to clean the belt and space below your mower’s deck of grass clippings, leaves or other debris.
  7. Inspect your blades: Dull blades can turn your grass tips brown, weak and prone to disease and pests. Check for worn, dull or bent blades and sharpen or replace them before firing up your mower.
  8. Change the spark plugs: At the beginning of the season, check your lawnmower’s spark plugs for signs of rust, corrosion or fouling and replace them if needed. A new set of E3 lawnmower spark plugs carries a lifetime warranty and will make your mower run cleaner, stronger and more efficiently.
