I've still got my users manual - it says the gap should be 0.030" (0.76 mm).

Toro does not sell secondhand snow blowers, but one can purchase a Toro snow blower used from a previous owner. The best place to look for one would be Craig's List or Ebay.
Depending of the surfaces to clear and the quantity of snow to remove different type of Toro snow blowers are available. Toro offers light electric snow blowers but also medium and heavy duty gas snow blowers. On average a new Toro snow blower cost $289 .This however isn't really meaningful . Toro snow blowers accomodate a wide range of budgets. Indeed the price of a new Toro snow blower goes from $79 for simple electric ones to $499+ for the latest gas ones.
