Learning how to lawn mower properly is a fundamental skill for any homeowner. Operating a lawn mower effectively involves more than just pushing a start button. It requires understanding your equipment, preparing your lawn, and using safe, efficient techniques to get a clean, healthy cut. This guide will walk you through everything you need to know, from pre-mow checks to post-mow maintenance.
How To Lawn Mower
This section covers the core principles and steps for using your mower correctly. Whether you have a push, self-propelled, or riding mower, these fundamentals apply.
Pre-Mow Preparation And Safety
Before you even think about starting the engine, proper preparation is crucial. This ensures both your safety and the health of your lawn.
Gear Up For Safety
Always wear appropriate protective equipment. This is non-negotiable.
- Sturdy, closed-toe shoes with good grip.
- Safety glasses or goggles to shield your eyes from debris.
- Hearing protection, especially for gas mowers.
- Long pants to protect your legs.
Clear The Lawn Area
Walk the area you plan to mow and remove any potential hazards. Look for:
- Sticks, stones, and toys.
- Dog bones or other pet items.
- Garden hoses or extension cords.
Clearing these objects prevents them from becoming dangerous projectiles or damaging your mower’s blades.
Check Your Mower’s Condition
A quick pre-use inspection can prevent problems. Make sure:
- The oil level is adequate (for gas mowers).
- There is enough fuel or a charged battery.
- The blades are sharp and securely attached.
- The tires are properly inflated.
- All safety features, like the blade control lever, are functioning.
Setting The Correct Mowing Height
One of the most common mistakes is cutting the grass too short. This stresses the grass, allowing weeds to take hold and making it more susceptible to drought.
For most cool-season grasses like Kentucky bluegrass or fescue, a height of 2.5 to 3.5 inches is ideal. For warm-season grasses like Bermuda or Zoysia, 1.5 to 2.5 inches is typical. Always follow the “one-third rule”: never remove more than one-third of the grass blade height in a single mowing. If the grass is very long, mow it down over several days.
The Step-By-Step Mowing Process
Now you’re ready to mow. Follow these steps for a professional-looking result.
- Start Your Mower Safely: For a gas mower, set it on a flat surface. Prime the engine if needed, set the throttle, and pull the starter cord firmly. For an electric mower, ensure the battery is inserted or the cord is plugged into a GFCI outlet, then press the start button.
- Choose Your Pattern: Alternating your mowing pattern each time prevents soil compaction and grass from leaning in one direction. Try mowing north-south one week, then east-west the next.
- Begin Mowing: Engage the blade and start walking at a steady, comfortable pace. Overlap each pass by a few inches to ensure you don’t miss any strips of grass.
- Navigate Obstacles: For trees and posts, mow around them in a circle. For slopes with a walk-behind mower, mow across the slope horizontally, not up and down, to maintain stability and prevent slips.
- Handle Clippings: If you have a bagger, empty it before it gets too full. For mulching, ensure the deck is clean and the blade is sharp for fine clipping. You can also side-discharge clippings onto already-cut areas if they are not too thick.
Post-Mow Cleanup And Maintenance
What you do after mowing is just as important for your mower’s longevity.
Always let a gas mower engine cool completely before storing it. Clean off any grass clippings and debris from the mower deck, undercarriage, and wheels. This prevents rust and keeps airflow optimal for next time. Check the blade for nicks and dullness; a sharp blade cuts cleanly, while a dull one tears the grass, turning the tips brown.
If you have a bagger, empty and clean it. For a mulching mower, make sure the mulching plug is clean. Store your mower in a dry place, and if it’s gas, consider adding a fuel stabilizer if you won’t be using it for a month or more.
Choosing The Right Lawn Mower
Knowing how to lawn mower starts with having the right tool for your yard. The best choice depends on your lawn’s size, terrain, and your personal preference.
Push Reel Mowers
These are human-powered, quiet, and emission-free. They are best for very small, flat lawns (under 1,000 sq ft) where the grass is kept consistently short. They provide a very clean cut but require more physical effort.
Electric Corded Mowers
These mowers are lightweight, quiet, and low-maintenance. They are suited for small to medium yards (up to 1/4 acre) with easy access to an outdoor outlet. The main limitation is the power cord, which you must manage carefully to avoid cutting it.
Electric Cordless (Battery) Mowers
These offer the convenience of gas mowers without the fumes or noise. They are excellent for small to medium lawns. Runtime depends on battery voltage and amp-hour rating. For larger yards, having a spare battery is essential to ensure you can finish the job.
Gas-Powered Mowers
Gas mowers provide the most power and runtime, making them ideal for large lawns (over 1/2 acre) or tough, overgrown grass. They require more maintenance, like oil changes, air filter cleaning, and spark plug replacement, and they are louder and produce emissions.
Riding Mowers And Lawn Tractors
For properties an acre or larger, a riding mower saves significant time and effort. Lawn tractors can also handle other tasks with attachments like carts or snow blades. They require more storage space and have a higher initial cost.
Essential Lawn Mower Maintenance
Regular maintenance keeps your mower running smoothly, extends its life, and ensures a better cut. Neglect can lead to poor performance and costly repairs.
After Every Use
- Clean grass clippings from the deck and undercarriage.
- Wipe down the mower to remove moisture and dirt.
- Check for any loose bolts or parts.
Regular Seasonal Maintenance
Perform these tasks at least once per mowing season, or as recommended in your manual.
Sharpening The Blade
A dull blade tears grass, leading to a brown, ragged appearance and increased disease risk. Sharpen the blade every 20-25 hours of use. You can use a file, bench grinder, or take it to a professional. Always disconnect the spark plug or battery before removing the blade.
Changing The Oil (Gas Mowers)
Old oil gets dirty and loses its ability to lubricate. Change the oil at the start of each season or after every 50 hours of operation. Run the mower for a few minutes to warm the oil, then drain it completely and refill with the type specified in your manual.
Replacing The Air Filter
A clogged air filter restricts airflow to the engine, reducing power and efficiency. Check the foam or paper filter each season and replace it if it’s dirty. This is a simple and inexpensive task.
Caring For The Spark Plug
The spark plug ignites the fuel in the engine. Remove it at season’s end, check the gap with a feeler gauge, and clean it or replace it annually. A fouled spark plug is a common reason a mower won’t start.
End-Of-Season Storage
Proper winterization prevents starting issues in the spring. For gas mowers, either run the engine until the fuel tank is empty, or add a fuel stabilizer to a full tank to prevent the gas from degrading and gumming up the carburetor. Clean the mower thoroughly, remove the battery (for electric or riding mowers), and store it in a dry place.
Troubleshooting Common Lawn Mower Problems
Even with good maintenance, issues can arise. Here are solutions to frequent problems.
Mower Won’t Start
This is the most common issue. Follow this checklist:
- Is there fuel in the tank? Is the fuel valve (if present) open?
- Is the spark plug wire connected securely?
- Is the battery charged (for electric/riding mowers)?
- Is the blade control lever (safety handle) fully engaged?
- For gas mowers, is the choke set correctly for a cold start?
- Has old fuel clogged the carburetor? You may need to drain it.
Mower Runs Rough Or Loses Power
- Dirty Air Filter: Replace or clean it.
- Old Fuel: Drain the tank and carburetor, and refill with fresh gas.
- Clogged Fuel Line: Check for blockages.
- Dull or Damaged Blade: A blade out of balance or very dull can strain the engine.
Uneven Or Ragged Cut
If your lawn looks striped or the grass tips are shredded, check these points:
- Dull Blades: Sharpen or replace the mower blade immediately.
- Uneven Tire Pressure: Check all tires and inflate them to the equal, recommended PSI.
- Mowing Too Fast: Slow down to allow the blade to cut cleanly.
- Wet Grass: Avoid mowing when the grass is wet, as it clumps and tears.
FAQ Section
How Do I Mow A Lawn For The First Time?
If the grass is very long, set your mower to its highest setting for the first pass. Then, lower it for a second pass a few days later, following the one-third rule. Clear the lawn of debris, plan your overlapping pattern, and take your time.
What Is The Best Way To Mow A Lawn?
The best way is to mow high and often, with a sharp blade, on a schedule that never removes more than one-third of the grass height. Alternate your mowing direction each time and keep the mower well-maintained.
How Do You Use A Lawn Mower Safely?
Always wear protective gear, clear the lawn of objects, never remove safety devices, and never put your hands or feet near the cutting deck while the engine is running. Be extra cautious on slopes and always turn off the mower before unclogging it.
Can I Mow Wet Grass?
It is not recommended. Mowing wet grass leads to uneven cuts, clumping that can smother the lawn, and slippery conditions. It also promotes the spread of lawn disease. Wait for the grass to dry for the best results.
How Often Should I Mow My Lawn?
Mow based on grass growth, not the calendar. During peak growing season in spring and fall, you may need to mow every 5-7 days. In the heat of summer, growth slows, and you might mow every 10-14 days. Always follow the one-third rule.
