Boost X Technology

The Boost X generates extra power through the brushless motor when sensing greater resistance on the blade while cutting longer / denser grass. This allows the mower to power through the tricky spots that regular mowers may struggle with.


The Self-Propelled Function powers the mower through the trickiest of terrains without the usual manual force. You will be amazed how easily it glides through the thickest lawns.

Side discharge & mulching

The mower folds down into an upright position for compact storage and transportability, perfect for storing in spaces like garden sheds.

Customer Reviews

2 reviews for 40V 46cm Cordless Lawnmower

  1. Philip Rees

    Mixed feelings. I’m pleased with it when it works, but it won’t tackle thick grass, unless it’s very dry and on a very high cut. The battery life quickly diminishes and will only last about 15 minutes after 6 months use

  2. Geoff Webster

    Great mower, in my opinion, it has all the power and durability of petrol equivalents. We have just moved into a new house with a bigger lawn and needed something to power through thick areas. Would definitely recommend.
