5.2 Depth Adjustment
The unit offers four levels of digging depth adjustment to suit various lawn conditions and seasons. The adjustment lever is located on the side of the main unit.
- Level 0: 0.16 inches (highest setting, for light dethatching or transport)
- Level 1: -0.16 inches
- Level 2: -0.31 inches
- Level 3: -0.47 inches (lowest setting, for aggressive dethatching or scarifying)
Select a higher setting for lighter work or new lawns, and a lower setting for dense thatch or scarifying. Always test on a small area first.

5.3 Dethatching vs. Scarifying
The 2-in-1 design allows you to switch between dethatching and scarifying modes by changing the rotor.
- Dethatching: Uses the spring tines to gently rake and remove loose thatch from the surface of the lawn. This is typically done in spring or early fall.
- Scarifying: Uses the rigid blades to cut into the soil, removing dense thatch and aerating the lawn. This is a more aggressive process, usually performed once a year on heavily thatched lawns.

5.4 Operation Tips
- Cord Management: Always be aware of the power cord's position to avoid cutting it. Work away from the power outlet.
- Working Pattern: For best results, work in straight, overlapping lines across your lawn. Avoid stopping in one place for too long.
- Empty Collection Bag: Regularly check and empty the 8-gallon collection bag to maintain optimal performance and prevent clogging.
