Look what it did......


Swweeping Mower with Kersten powered sweeper


A Kersten powered sweeper with a collector and a side gulley brush sweeps the detritus that the moss is growing in and collects the debris in the collection box. This surface may now dry much more quickly as nothing remains to store moisture reducing the possibility of future moss growth. A periodical sweep will keep this area free from moss and weeds.


Kersten sweepers can be pedestrian operated or tractor mounted. They are available in working widths of 75cm to 3 metres.  See our website for details.........Chemical Free Weed Control From Kersten
