First, you should check the condition of the machine. Take time to inspect it carefully. You can choose to open it up so that you can see the parts if they are still in good shape and functional. Try to have a test run to see whether it can handle snow-blowing jobs. Take note that used blowers will not function like new models do, so lower your expectation.
Second, look for a machine that is cheap and easy to maintain. There are types of snow blower that need low level of maintenance while others require frequent servicing. You should look for one that will not frequent servicing as it is expensive and can give you big hassle.
