Learning how to cut grass with lawn mower is a fundamental skill for any homeowner. A clean, even cut begins with understanding your mower’s proper cutting height and pattern. This guide will walk you through everything you need to know, from pre-mow checks to finishing touches, ensuring your lawn looks its best after every mow.
How To Cut Grass With Lawn Mower
This section covers the core process. Following a consistent method protects your grass and your equipment. The goal is to cut the grass, not tear it, which requires sharp blades and the right technique.
Pre-Mow Lawn Preparation
Taking a few minutes to prepare your lawn and mower makes the actual cutting faster and safer. Rushing this step can lead to poor results and potential damage.
First, walk the area you plan to mow. Look for and remove any debris like sticks, toys, rocks, or dog bones. These objects can become dangerous projectiles or damage your mower’s blade. Next, check your grass. It should be completely dry. Mowing wet grass leads to clumping, an uneven cut, and can clog your mower deck.
- Clear all debris from the lawn.
- Ensure grass is dry to the touch.
- Check your mower’s oil and fuel levels.
- Inspect the mower blade for sharpness and damage.
Setting The Correct Cutting Height
One of the most common mistakes is cutting grass too short. Each grass type has an ideal height. A good rule is to never remove more than one-third of the grass blade in a single mowing. This promotes deeper roots and a healthier lawn.
Consult your mower’s manual to adjust the wheel heights. For most cool-season grasses like Kentucky bluegrass, a height of 2.5 to 3.5 inches is ideal. Warm-season grasses like Bermuda can be cut shorter, around 1 to 2 inches. When in doubt, set it higher. You can always lower it on the next pass if needed.
Choosing Your Mowing Pattern
Alternating your mowing pattern each time you cut is crucial. Mowing in the same direction every week causes grass to lean and grow in that direction, leading to an uneven appearance and soil compaction from the wheels.
For a standard rectangular lawn, mow in parallel lines. Next time, mow perpendicular to those lines, or even on a diagonal. For circular lawns, start on the outside and work your way inward in a spiral. Changing the pattern encourages upright growth and creates those attractive stripes.
Basic Patterns To Alternate
- North-South lines one week.
- East-West lines the following week.
- Diagonal lines for a third mowing.
- Spiral pattern for circular areas.
The Step-By-Step Mowing Process
Now you’re ready to start the engine. Follow these steps for a efficient and effective mowing session. Always prioritize safety by wearing sturdy shoes and eye protection.
- Start your mower on a flat, hard surface like your driveway.
- Begin mowing along the perimeter of your lawn. This creates a turning track for the rest of the mow.
- Work back and forth in straight, overlapping lines. Overlap each pass by about 2-3 inches to ensure no strips are missed.
- Use a steady, walking pace. Do not rush.
- When turning, do so on your hard perimeter track to avoid tearing the grass.
- If the mower clogs with clippings, turn it off and wait for the blade to stop before clearing it.
Essential Lawn Mower Maintenance
A well-maintained mower is the key to a good cut. Simple, regular upkeep prevents most problems and extends the life of your machine significantly. Neglect can lead to a ragged cut and costly repairs.
Sharpening The Mower Blade
A dull blade tears grass, leaving brown, frayed tips that make your lawn look dull and are more suseptible to disease. You should sharpen the blade at least twice per mowing season, or more often if you hit rocks or debris.
Disconnect the spark plug wire first for safety. Tip the mower on its side (with the air filter facing up on gas mowers). Use a wrench to remove the blade. You can sharpen it with a metal file or bench grinder, maintaining the original cutting angle. Always balance the blade before reinstalling it.
Cleaning The Mower Deck
Grass clippings, moisture, and dirt accumulate under the mower deck. This buildup reduces cutting efficiency and airflow, leading to clumping. Clean the deck after every few uses.
After mowing, let the mower cool down. Then, use a putty knife or brush to scrape away the caked-on grass. A quick hose-down can help, but avoid direct spray on the engine or electrical components. Let it dry completely before storing.
Seasonal Care And Storage
Proper end-of-season preparation protects your mower during the off months. For gas mowers, this is especially important to prevent fuel system issues.
- Run the mower until the fuel tank is empty, or add a fuel stabilizer.
- Change the oil and replace the air filter.
- Remove the spark plug and add a small amount of oil to the cylinder, then pull the starter cord slowly to coat the interior.
- Store the mower in a clean, dry place, preferably covered.
Advanced Tips For A Perfect Lawn
Once you’ve mastered the basics, these techniques can elevate the look and health of your turf. They focus on how you handle the clippings and adapt to conditions.
To Bag, Mulch, Or Side Discharge
Your mower likely has three clippings management options. Each has its place. Bagging collects clippings for a clean look, ideal if the grass is too long or you want to prevent thatch. However, it removes nutrients.
Mulching uses a special blade to cut clippings finely and return them to the lawn. This acts as a natural fertilizer. It works best when you mow frequently and the grass is dry. Side discharge is the default for many mowers, simply ejecting clippings onto the lawn. It can work if the grass is not too long.
Mowing On Slopes And Hills
Safety is paramount on inclines. With a push mower, always mow across the slope, not up and down. This prevents the mower from rolling back onto you. If you must mow up and down, use extreme caution and wear shoes with excellent grip.
For riding mowers, consult your manual. Most recommend mowing up and down slopes, not across, to avoid tipping over. Never make sudden turns on a hill.
Dealing With Overgrown Grass
If your lawn has gotten too long, never cut it to the desired height in one go. This shocks the grass and exposes stems normally shaded. Instead, use the one-third rule over multiple mows.
Set your mower to its highest setting for the first cut. Then, wait a few days and lower the setting for a second pass. You may need a third pass to get it down to the ideal height. This patience results in a healthier lawn.
Frequently Asked Questions
What Is The Best Way To Cut Grass With A Lawn Mower?
The best way involves sharp blades, cutting dry grass at the correct height, and alternating your mowing pattern each time. Always remove no more than one-third of the grass blade length.
How Do You Mow A Lawn For Beginners?
Beginners should start by clearing the lawn, checking mower settings, and mowing the perimeter first. Then, mow in straight, overlapping lines at a steady pace. Wear protective footwear and eye wear.
What Pattern Should I Use To Cut My Grass?
You should change your pattern regularly. Alternate between parallel lines, perpendicular lines, and diagonal lines. This prevents soil compaction and encourages the grass to grow straight up.
Is It Better To Mow Or Mulch Grass?
Mulching is generally better for lawn health as it returns nutrients to the soil. However, bagging is preferable if the grass is very long or wet, to prevent clumps that can smother the grass beneath.
How Often Should You Cut Your Grass?
Mow often enough so you never remove more than one-third of the grass height. For most lawns in the growing season, this means mowing once a week. Growth slows during hot, dry periods or in the fall.
