The last thing you want when the grass starts to grow is a mower that won't start or, even worse, breaks down in the middle of the job. Lawn mowers and garden tractors often need some care before they can be used regularly after sitting all winter.
The good news is Most owners can do a basic spring tune-up in an afternoon, and it's easy and cheap. Replacing a few key wear items now helps prevent breakdowns, improves performance, and extends the life of your equipment.
Use this step-by-step guide to prepare your machine for mowing season.
Step 1: Change or sharpen the blades
Your blades do the real work, and if they are dull or broken, they will tear grass instead of cutting it cleanly. This makes your lawn look uneven and makes the engine work harder.
Look for:
- Dull edges
- Chips or bends
- Too much wear
If they are worn out, get new ones. New blades cut better, work better, and make mowing faster.
Step 2: Check the belts
During the winter, deck and drive belts can crack or dry out. If your belt is weak, it could slip, squeal, or break at any time, leaving you stuck in the middle of a job.
Take off the deck cover and look for:
- Fraying or cracks
- Shiny or glazed spots
- Not enough tension
If you see wear, change the belt now instead of risking downtime later. Compared to the trouble of a breakdown, belts are cheap.
Step 3: Change the oil and oil filter.
Used oil accumulates grime and moisture, which can shorten an engine's lifespan. Beginning the season with fresh oil helps keep the engine cooler and safeguards its internal components.
According to the instructions from the manufacturer, warm up the engine a little, drain the old oil, replace the filter, and fill it up with new oil. This is one of the most important things you can do to keep your car in good shape.
Step 4: Clean the fuel system
If you leave gas in your car all winter, it can go bad and make varnish build up in the fuel lines and carburetor. This often causes hard starting, sputtering, or rough idling.
To start:
- Draining the old fuel.
- Swapping out the fuel filter.
- Filling up with fresh gas.
Consider a fuel treatment or cleaner to dissolve any buildup and improve performance, if necessary.
Step 5: Change the air filter
When the air filter is clogged, it blocks airflow, which makes your engine work harder and use more gas. It can also lose power when you cut thick grass.
If your filter is dirty or stained, check it and change it. A clean filter makes it easier for your engine to breathe and work better.
