Most two-stage snow blowers have a large gap or space between the impeller blades and the cylindrical chamber surrounding it. As the working time of snow blower increases, the gap gradually let in more and more snow and slush and build up in the internal space. This issue can cause clogging issues and reduced snow throwing distance, greatly decreasing work efficiency. This is a common design fault for many snow blowers. One of the easiest and quickest solution is to modifying the blades by adding a strip of durable rubber to each of them to reduce or eliminate the gap. It is also recommended that all blades should be modified to ensure the mechanic balance while the blowing is running. Note this modify kit is for improving the performance of two-stage blowers. For single-stage blowers or those with small (
