Additionally, the foldable handle feature allows for compact storage, making them ideal for garages and sheds with limited space.

Safety features have not been overlooked, with both mowers equipped with a blade brake mechanism that stops the blade quickly when the user releases the handle. This ensures added safety, especially in households with children or pets.
