You can adjust its cutting heights between 22 to 65mm with one simple lever, offering 6 different height settings. The spacious 60-litre canvas grass bag easily collects grass clippings. Additionally, by fitting the Mulching Plug (supplied with the mower), you can finely cut and redistribute your grass clippings back onto the lawn surface as you mow.
