For purposes of example we'll use a rectangular style driveway. I personally plow my 75X30 driveway with a 60 inch plow mounted to my Polaris 800 ATV.
I start by angling my blade all the way extreme left or right (your choice) and start at one end of my driveway and go right down the middle to the opposite end. I back up and start back at the beginng plowing the same way the blade is until I come along the side's of the driveway where it meets the grass. Repeat with the blade facing the opposite way for the remaing half of the driveway. Of course this only works if you have enough space on each side of your driveway to move the snow to. If you don't have the room you can start on the side that has the smallest amount of room and move the snow to the opposite side by repeating the process with the blade angled the direction you want the snow to go. The most important part of snow plowing ESPECIALLY at the beginning of the season is make sure that you push the snow far enough away from the side of what you are plowing to allow you plenty of space to get the snow out of the way for the rest of the winter.
Just before your plow makes contact with grass or gravel when you transition from the asphalt raise the plow blade about a inch. This will still allow plenty of snow to get moved and save you from doing alot of damage to your grass or whatever other surface you may have.
