Main function

The 390 mm lawn mower blade for Parkside lawn mowers – Ref. 7911200645 is designed to cut grass by rotating at high speed beneath the mower deck.

Driven by the motor, it cuts grass blades evenly and efficiently, ensuring a neat lawn and a uniform cutting height.

Its design also helps promote airflow beneath the cutting deck, making it easier to direct the cut grass towards the collection system, depending on the mower's configuration.

A properly sharpened, balanced and securely fastened blade ensures a clean cut, reduces vibrations and minimises strain on the motor.

A lawn mower blade in good condition is therefore essential for maintaining cutting performance, achieving consistent results and ensuring the reliable operation of the Parkside lawn mower.

When should the lawn mower blade be replaced?

The 390 mm lawn mower blade for Parkside lawn mowers – Ref. 7911200645 should be replaced in the following cases:

• Cracks, fractures or significant chips

• Abnormal vibrations during mower operation

• Unbalanced blade that can no longer be properly balanced

• Uneven cutting or grass being torn rather than cut

• Blade damaged after hitting a stone, tree stump or another obstacle

• Excessive wear around the central mounting hole or fixing points
