Re: Should I add a snow deflector flap?
Fluffy snow is only fluffy until it meets up with a plow. A tall, heavily curved blade will help with what wants to come over the top, but nothing helps what spills off to the side. This I learned through my teen years using a scraper to clear 3 driveways every time it snowed. For the past 40 years I've used a loader that leaves windrows as soon as the bucket is full, so fluffy snow spilling over the top or out the side is not a problem I catch it the next pass. It's only a tiny percentage of the snow that has to be moved in any event, and not really worth going to any lengths to prevent.
With my loaders, I've straight pushed 250' from the street to my snow dump and then did each successive passes down the same pass line to make use of the windrows to contain the snow from exiting sideways. For your situation, with deeper snowfalls, angle the blade and make the first pass down the edge of the driveway on each side to give maximum width. Then do the successive passes starting from the middle and working across the first cleared pass.
That makes for less side loading while pushing and an extra pass in each direction to clear the full width, but the effort for the tractor is a lot less and it can travel faster.
When I was in the air force, I watched the maintenance crews clear 300' square blocks of flight line in short order using a similar technique. The truck never pushed more snow at a time than what the blade faced on the first pass. The operator spiraled in, one blade width at a time pushing the snow to the outside of the spiral, then busted through the windrows to the outside and did it again and again to push each windrow one blade width closer to the outside edge until all of the snow was at the outside for the snow blower to blow it into trucks and haul it away.
The truck did the whole operation at speed, slowing down only for the corners and as the spiral tightened. He effectively cleared about 70 miles of one lane road in about 4-5 hours by the time he finished the whole 1200' of flight line.
