## Long description

Key specifications
Working width: 505 mm
Blade depth: 200 mm
Intended use: scarifier cutting/knife blade for moss and thatch removal
Material: wear-resistant metal suitable for cutting organic lawn debris
How to use
Before installation, disconnect power to the scarifier and follow the manufacturer’s instructions for safe replacement of cutting parts. Remove the scarifier’s cover or access panel to reach the cylinder or mounting shaft, then unfasten the retaining hardware securing the worn blade. Align the replacement blade so the cutting edge and mounting holes match the shaft orientation and secure it with the original fasteners to the recommended torque. After installation, check that the blade rotates freely without contact with housing parts and perform a short test run at low speed to confirm correct fit and balance.
Usage recommendations
For effective and safe operation, use the blade with compatible scarifier models and maintain a regular inspection routine: check for bent or chipped edges, remove debris after each session, and replace the blade when signs of excessive wear appear. Observe all safety guidelines of the scarifier manufacturer, wear appropriate protective equipment, and avoid using the blade on hard surfaces or where it may contact stones or metal objects.
