The original plows were pulled in Egypt and Sumeria by workers and oxen. When dealing with snow, today we hook them up to winter service vehicles, or even the front of our personal trucks. The right kind of plow can improve efficiency and expenses. Large plows may remove more snow, while smaller plows are more precise. How the plow is hitched to the vehicle is important too, as manual adjustments are time-consuming, especially when compared to the newer drop-and-go designs.
