Lawn mower blade Gardena 4122-20 PowerMax Duo

The GARDENA 4122-20 PowerMax Duo replacement blades are double-edged rotary blades designed for the PowerMax Duo mower. Made from hardened steel and supplied as a set of two, they are engineered to maintain precise cutting performance, efficient grass collection and reliable operation with GARDENA’s DuoBlade Technology.

Advantages

These replacement blades are manufactured from hardened steel for long service life and resistance to normal garden wear. Their aerodynamic profile reduces drag on the brushless motor, contributing to smoother, more energy-efficient operation. Mounted at 90 degrees to each other, the blades produce strong airflow that improves grass pickup into the collection bag and helps achieve an even, neat finish.

How to use

Usage recommendations

Inspect blades regularly for wear, nicks or bends and replace as soon as cutting performance or grass collection is affected. Maintain correct blade torque and balance; do not attempt to sharpen or modify hardened blades beyond the manufacturer’s guidance. Use genuine GARDENA replacement blades to ensure compatibility with PowerMax Duo models.
