RM 443 T
Versatile petrol lawn mower with 1-speed gearing
General
With a cutting width of 41 cm is the STIHL RM 443 T petrol lawn mower is ideal for amateur gardeners who seek agile and fast manoeuvring. Particularly on medium-sized lawns, its effort-saving 1-speed gearing ensures for fast mowing. Well thought-out details such as the super soft grip and easy running wheels provide for comfortable handling. On this mower, the level indicator on the grass catcher box shows you when the time has come to empty the box. For ease of working, the plastic grass catcher box is simple to open and empty thanks to a fold-open mechanism. The central cutting height adjustment can be adjusted to the desired lawn height in six settings. If you would like to also mulch your lawn using the RM 443 T, this petrol lawn mower can be converted to a Multi-mower with the appropriate mulching kit available as an accessory.
