Ok I plow a lot of private roads, and up to this year have always plowed them with an f 350 9' diamond blade. Now i use a 10' fisher blade on an f 650. OK this is what i can tell you, the deeper the curve in the plow, the higher you can pile snow, when casting it to the side. If you can add some sort of extension to the curve of your blade. Then keep your speed up, and you shouldn't have a problem. In 96 this method worked fine plowing many private roads, and in 3 weeks time we got 3' of snow. Plowing private roads and long drives is almost a specialty type of plowing in my mind. If you plow a lot of long runs like that, i would advise you to buy a Diamond for your next plow, which will stack snow very high. Also if there are any curves in the drive, push back as far as you can. So if you have to dump snow someplace you have a few turn offs on the side of the drive.<p><br>Geoff
