Replacing the air filter: If the filter is disposable or damaged beyond repair, it needs to be replaced. Find a new air filter that matches the model and size of your mower.
Setting the Mower Height
The height of your mower’s deck determines the length of grass you cut. The ideal height varies depending on the type of grass you have and the season. As a general rule, you should set the mower height higher in hot, dry weather to reduce stress on the grass. In cool, wet weather, you can set the mower height lower to promote healthy growth.
Here are some tips for setting the mower height:
- Consult your mower’s manual for the recommended height range for your type of grass.
- Start by setting the mower height at the highest recommended setting.
- Mow your lawn and observe the results. If the grass is too long, lower the mower height by one notch.
- Continue to mow and adjust the mower height until you find the ideal setting for your grass.
- Remember to follow the “one-third rule” when mowing your lawn. This means never removing more than one-third of the grass blade at a time. This helps to keep the grass healthy and prevents it from going into shock.
| Grass Type | Ideal Height (inches) |
|---|---|
| Cool-season grasses (e.g., fescues, ryegrasses) | 1.5-2.5 |
| Warm-season grasses (e.g., Bermuda, zoysia) | 2-3 |

Starting the Engine
Locate the starter cord and pull it firmly and evenly. Some mowers may require gentle priming while pulling the cord.
Mowing Patterns for Optimal Results
To achieve a healthy and uniform lawn, follow these mowing patterns:
- Straight Lines: Mow in parallel rows, overlapping each row by about 25% to avoid missed spots.
- Alternating Rows: Alternate the mowing direction between rows to reduce soil compaction and promote grass growth.
- Checkerboard Pattern: Create a grid by mowing alternate squares in opposite directions to minimize wheel tracks and improve coverage.
- Spiral Pattern: Start from the center of the lawn and mow in a spiral outward, gradually increasing the radius to avoid creating ruts.
- Varying Patterns: Rotate different mowing patterns each time to prevent rutting and promote even grass growth.
- Avoid Overlapping: Overlapping rows excessively can smother the grass and limit its growth potential.
- Proper Cutting Height: Maintain an appropriate cutting height for your grass type. Generally, remove no more than 1/3 of the blade length per mowing.
- Mulching: Opt for mulching mowers that finely chop grass clippings and return them to the lawn, providing nutrients and reducing waste.
Troubleshooting Starting Problems
If your mower fails to start, check the following:
| Problem | Solution |
|---|---|
| No Fuel | Refill the fuel tank. |
| Faulty Spark Plug | Inspect and replace the spark plug. |
