Its very important to know your costs on your equipment, especially for the snow season when they are working in the cold for long periods of time. One common mistake that snow contractors tend to make is thinking that a "paid off" piece of equipment doesn't cost them anything anymore. The fact is that, this isn't true. Just because you aren't paying off the equipment anymore, doesn't meant that there aren't any repair, maintenance, or overhead costs to go with it.
