this is not a new idea , i have been using the freelander fitted with a snow plough for quite a few years now, its very capable of clearing roads and car parks only ever cleared depth of 8 inches, but im sure it could handle more
the plough is made from old rubber conveyer belt fitted to a steel frame, the A frame runs from the front to the rear and is attached to the tow ball, with a couple of links at the front attached to the antiroll bar keeping it in line , works a treat
there is just never enough snow to keep me busy
