5. Operation
Before operating, ensure the machine is fully assembled, the correct blade cartridge is installed, and all safety precautions are observed.
5.1. Selecting the Right Blade
- Dethatcher Blade: Use this blade to remove dead grass, moss, and other organic debris (thatch) from the lawn surface. This allows water, nutrients, and air to reach the soil and grass roots more effectively.
- Scarifier Blade: Use this blade for deeper aeration, cutting into the soil to improve drainage and encourage stronger root growth. This is ideal for compacted lawns or preparing for overseeding.

5.2. Adjusting Cutting Depth
The MZK Dethatcher/Scarifier features a 4-position height adjustment mechanism. This allows you to select the appropriate working depth for your lawn conditions.
- Locate the depth adjustment lever on the side of the unit.
- Move the lever to select one of the four available depth settings. Refer to the diagram for corresponding depths.
- Start with a higher setting for initial passes, especially if your lawn has significant thatch. Gradually decrease the depth as needed.
