Scarab International, LLLP Manufactures Windrow Turners for composting any material that is organic or bio-degradable. The Scarab Windrow Turner works in a pyramid shaped windrow that vary in size. The windrows may range from 8 feet wide at the base up to 27 feet at base. The windrows can be 5 feet to 11 feet tall. The Scarab Windrow Turner uses a tunnel the shape of the pyramid and uses a rotating drum with fails on the drum. This action helps aerate the windrow to create heat because of the moisture that is in the windrow. The heat helps Mother Nature decompose the matter into a viable fertilizer, landscape material or topsoil after a designated time and turning process.
