Adjusting Cutting Height
The cutting height can be adjusted to suit your lawn's needs, ranging from 0.5 inches to 2.5 inches.
- Locate the height adjustment levers or knobs on the side of the mower, near the wheels.
- Adjust both sides to the desired height setting. Ensure both sides are set equally to maintain an even cut.
- A higher setting is recommended for taller grass or for the first cut of the season.

Mowing Your Lawn
- Prepare the Area: Before mowing, remove any obstacles such as toys, stones, or branches from the lawn.
- Pushing Technique: Push the mower at a steady, comfortable pace. Overlapping each pass slightly will ensure an even cut.
- Grass Height: For best results, avoid cutting more than one-third of the grass blade length at a time. If grass is very tall, consider raising the cutting height for the first pass and then lowering it for a second pass.
- Direction: Vary your mowing pattern each time to prevent matting and promote healthier grass growth.

5. Maintenance
Regular maintenance will extend the life and performance of your reel mower.
Cleaning
- After each use, clean grass clippings from the blades and undercarriage. A stiff brush or hose can be used.
- Ensure the mower is dry before storing to prevent rust.
Blade Care
- The heat-treated alloy steel blades are designed for durability, but regular inspection is recommended.
- If blades become dull, they can be sharpened by a professional or with a reel mower sharpening kit.
- Apply a light coat of lubricant (e.g., WD-40) to the blades and moving parts periodically to prevent rust and ensure smooth operation.

6. Troubleshooting
Here are solutions to common issues you might encounter:
- Mower not cutting effectively:
- Check if the cutting height is set too low for the current grass height. Raise the cutting height.
- Inspect blades for dullness or damage. Sharpen or replace as needed.
- Ensure the cutting bar is properly adjusted against the reel blades.
- Mower is difficult to push:
- Grass may be too tall or thick. Raise the cutting height or make multiple passes.
- Check for debris (twigs, rocks) caught in the blades or wheels. Clear any obstructions.
- Lubricate moving parts if they feel stiff.
- Uneven cut:
- Ensure both sides of the cutting height adjustment are set to the same level.
