I have had a Kombi System with attachments that help me do things around my yard for years. Here in Winnipeg Mb. Canada we deal with ice on the road and backlanes in the spring. When the melt begins water pools on the backlanes and one must manually chip ice to form a trench for the water to flow toward the storm drain. If I had an ice chipping attachment that I could use on my Kombi it would make life easier. It only has to chip a trench 2 inces wide and if there was a way to also adjust the depth of the cut to prevent chipping the concrete surface I would be happy. Looking forward to the new Stihl Ice Trenching attachment. Thanks Tom.
