To mow your lawn properly, start by preparing the mower (check oil, fuel, and sharpness) and clearing the lawn of debris. Set the mower height to remove no more than one-third of the grass blade length. Mow in overlapping straight lines or alternating patterns, keep the grass dry, and vary your pattern each time. After mowing, clean the mower and consider leaving grass clippings on the lawn for nutrients.
Preparing Your Lawn and Mower for Mowing
Proper preparation is the foundation of a successful mowing session. Taking the time to check your equipment and clear the lawn ensures safety, prevents damage, and produces a cleaner cut.
Perform Pre-Operation Safety Checks
Before starting your mower, inspect it thoroughly. Check the oil level and top it up if needed, ensure there is enough fuel, and verify that the air filter is clean. Inspect the blade for sharpness and damage, and replace or sharpen it if necessary. Check that all safety guards are in place and that the mower starts and runs smoothly before you begin.
Clear the Lawn of Debris
Walk the lawn and remove sticks, stones, toys, and other debris that could be thrown by the mower or damage the blade. Debris not only poses a safety risk but can also dull the blade quickly and cause uneven cuts. Pay special attention to areas near trees and flower beds where fallen branches and leaves tend to accumulate.
Setting the Correct Mowing Height
Setting the correct cutting height is one of the most important factors in maintaining a healthy lawn. Cutting too short stresses the grass, while cutting too high can leave the lawn looking unkempt.
Understand the One-Third Rule
The one-third rule is a fundamental principle of lawn care: never remove more than one-third of the grass blade length at any single mowing. Removing more than this stresses the grass, weakens the root system, and makes the lawn more susceptible to weeds and disease. If your grass has grown too tall, mow it at a higher setting first, then lower the deck and mow again a few days later.
Adjust the Cutting Height for Your Grass Type
Different grass types have different ideal cutting heights. Cool-season grasses, such as Kentucky bluegrass and fescue, generally do well at a height of about 2.5 to 3 inches. Warm-season grasses, such as Bermuda and zoysia, are often kept shorter, around 1 to 2 inches. Adjust your mower deck accordingly, and raise the height slightly during hot, dry periods to help the grass retain moisture.
How to Adjust the Deck on Push and Riding Mowers
On push mowers, the cutting height is typically adjusted by moving a lever on each wheel to one of several preset positions. On riding mowers, there is usually a single lever or a dial that raises or lowers the entire deck. Always adjust the height with the mower turned off and the engine cool, and ensure the deck is level from side to side for an even cut.
Choosing and Executing an Effective Mowing Pattern
The pattern you use to mow affects both the appearance of your lawn and the health of the grass. A well-planned pattern ensures an even cut and prevents ruts from forming.
Alternate Your Mowing Direction
Mowing in the same direction every time can cause the grass to lean in one direction and can create ruts over time. Alternate your pattern each session, mowing horizontally one week, vertically the next, and diagonally after that. This encourages the grass to grow upright and prevents the soil from becoming compacted in specific wheel tracks.
Use Overlapping Straight Lines
For the most uniform cut, mow in straight lines with each pass slightly overlapping the previous one. Overlapping by a few inches ensures that no strips of grass are missed and prevents scalping at the edges of each pass. At the end of each row, turn carefully and begin the next pass, keeping your lines as straight as possible for a clean, professional appearance.
Handle Turns and Obstacles Carefully
When you reach the end of a row, make a wide turn rather than a sharp one to avoid damaging the grass and creating ruts. Around trees, flower beds, and other obstacles, slow down and trim carefully. For tight spaces, you may need to use a string trimmer to finish the edges after mowing.
Mowing Technique and Safety During Operation
Safe operating practices protect you, your equipment, and your lawn. Understanding how to handle slopes and obstacles can prevent accidents and damage.
Mow Slopes Safely
When mowing slopes, the safest approach depends on the type of mower you are using. With a push mower, mow across the slope (side to side) rather than up and down to reduce the risk of the mower slipping. With a riding mower, mow up and down the slope instead of across it, as riding mowers are more stable when traveling vertically. Never mow extremely steep slopes with a riding mower, and always be aware of wet conditions that make slopes more hazardous.
Handle Obstacles with Care
When approaching trees, rocks, or flower beds, slow down and mow around them carefully. Avoid hitting obstacles with the mower deck, as this can damage both the obstacle and the mower. For areas the mower cannot reach, such as tight corners or along fences, use a string trimmer to finish the job.
Post-Mowing Care and Cleanup
What you do after mowing is just as important as the mowing itself. Proper aftercare keeps your equipment in good condition and returns nutrients to your lawn.
Decide Whether to Bag, Mulch, or Side-Discharge
Grass clippings are a valuable source of nutrients. Mulching, which involves cutting the clippings finely and leaving them on the lawn, returns nitrogen to the soil and reduces the need for fertilizer. Bagging is useful when the grass is very long or wet, or when you want a clean appearance. Side-discharging spreads clippings to the side and is a middle-ground option, though it can leave visible clippings on the lawn.
Clean the Mower Deck and Store Safely
After mowing, remove any grass clippings from the underside of the deck to prevent rust and buildup. A hose attachment or a scraper can be used for this purpose. Allow the mower to dry before storing it, and store it in a dry, sheltered location. For gas mowers, consider draining the fuel or adding a fuel stabilizer if you will not be using the mower for an extended period.
