Also asked, how high should snow plow be set off ground?
On relatively flat surfaces, put shoes on your plow, and adjust them so the plow's blade is between a half-inch or so above the ground. This will prevent you from digging into gravel in most cases. However, you should also use your senses and go slow. Speed kills when you're plowing a gravel drive or parking lot.
Subsequently, question is, how much is a plow worth? These products generally range from about $3,000 - $4,500; but of course, the specific price will depend on the size and model of the plow.
Keeping this in consideration, how many inches of snow do I need to plow?
If you expect snow accumulation of greater than one inch, you should plan on plowing. If snow gets too deep, it may actually become almost impossible to plow. If snow sits too long, there's also a greater chance of it hardening up, which makes snow removal that much more difficult.
How wide is a plow truck?
Plows start at widths of 6½ feet for Jeeps and small pickups and go up to 9- and 10-foot-wide plows for dump trucks. Most standard pickup trucks are best suited to 6½- and 7½-foot plows, half-ton trucks use 7 or 7½-foot blades and ¾- and 1-ton trucks typically use 7½-foot and 8-foot blades.
