Mowing Techniques
To achieve a clean and even cut, follow the following techniques:
- Overlap each pass by about one-third to avoid leaving uncut grass.
- Mow in straight lines, avoiding sudden turns or stops.
- Vary your mowing direction occasionally to prevent ruts in the lawn.
- Avoid mowing wet grass, as it can clog the blades and lead to uneven cuts.
- Keep the blade sharp to ensure a clean cut and prevent tearing the grass.
Troubleshooting Common Deck Problems
If you encounter any problems with the deck, refer to the following table for troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven cut | Dull blade, uneven deck height, clogged blades | Sharpen the blade, adjust the deck height, or clean the blades |
| Excessive vibration | Loose deck bolts, damaged blade | Tighten the deck bolts or replace the blade |
| Scalping | Deck height set too low | Raise the deck height |
Adjusting Cutting Height and Speed
Adjust the Cutting Height
Locate the deck lift lever typically positioned near the operator’s seat. Move the lever forward or backward to raise or lower the mower deck, adjusting the cutting height. For a shorter cut, move the lever forward to lower the deck. For a taller cut, move the lever backward to raise the deck. Refer to the manufacturer’s recommended cutting height for your lawn type and specific conditions.
