Mobility & Convenience

The 2-wheel, self-propelled RM40SPB is a rear roller lawnmower – meaning it can achieve a professional looking striped finish.

Make cords a thing of the past. The RM40SPB doesn’t need sockets, is not limited to the length of a cord and has no battery to recharge – just fill up with fuel and away you go!


The 6 position height adjustable 40 cm/16″ rotary blade allows for maximum adaptability and can cope with various terrain and grass lengths.

The rear roller will not only give your lawn a traditional striped finish, but also supports the lawnmower when the front wheels are in line with the border edge, allowing you to mow right up to the edge of flowerbeds and borders.

The RM40SPB comes with a huge rear grass collection basket (60 L) to collect grass clippings.
