Beautiful Stripes with a Heavy Steel Rear Roller

For those who appreciate a perfectly striped lawn, the COBRA RM433SPBI includes a heavy-duty steel rear roller designed for professional-quality results. The roller presses the grass in alternating directions, creating clean, defined stripes that elevate the appearance of your garden. It also stabilises the mower, allowing you to cut neatly along flowerbeds and edges without scalping. Every pass delivers a smooth, elegant finish that transforms your lawn into a beautifully maintained landscape.

Adjustable Cutting Heights for Precision Control

Offering six adjustable cutting heights ranging from 17mm to 75mm, the RM433SPBI provides flexibility for every lawn type and season. Adjusting the height is quick and easy using a single central lever, allowing you to customise your cut in seconds. Choose a lower setting for a short, refined finish or a higher one for tackling thicker grass. This versatility ensures consistent results and the perfect look all year round.

Efficient Grass Collection and Clean Results
