Seasonal Mower Maintenance Checklist: What Parts to Replace (and When)

A well-maintained mower lasts decades. A neglected one? It'll let you down on the hottest Saturday of summer. Here's the seasonal checklist our team swears by — built around the Australian mowing calendar.

Start of Season (August–September)

  • ✅ Blade: Sharpen or replace if nicked or bent
  • ✅ Air filter: Replace paper filters; clean foam filters with soapy water
  • ✅ Spark plug: Replace annually — they're cheap and make a huge difference to starting
  • ✅ Oil & oil filter: Full oil change before the season begins
  • ✅ Drive belt: Inspect for cracking, fraying, or glazing — replace if in doubt
  • ✅ Battery (ride-ons): Charge and load-test; replace if it won't hold charge

Mid-Season (November–January)

  • ✅ Blade: Re-sharpen or swap if cutting quality drops
  • ✅ Air filter: Check and clean — dust and grass clippings clog filters fast in dry conditions
  • ✅ Fuel filter: Replace if the engine is hesitating or hard to start
  • ✅ Tyres (ride-ons): Check pressure and inspect for wear

End of Season (April–May)

  • ✅ Full oil change: Don't store with old oil — acids in used oil corrode engine internals
  • ✅ Fuel: Either run the tank dry or add a fuel stabiliser
  • ✅ Blade: Remove, clean, and store or replace ready for next season
  • ✅ Deck: Scrape off caked grass, check for rust, and touch up with paint if needed
  • ✅ Battery: Remove and store on a trickle charger over winter

Our rule of thumb: if a part costs less than $20 and you're not sure, just replace it. The cost of a breakdown mid-mow is always higher.
