Just curious Atsah, if you have a fence - what is on the other side of it that you can blow into another area?
I had a similar problem with using a plow blade concept for my location. One reason was it was hard on all the concrete sidewalks and patios and driveways - and we have quite a bit of all three. I found a product by Ratchet Rake called a snow edge and that has worked quite well for me to do controlled plowing, then move the piles as I'm finishing each plow run. I lift it right over piles and unlike a back blade - the snow gets better compacted so it takes up less space and I'm also not driving over the snow before the plowing gets to it.
They claimed with inexpensive implement could go up to 32 hours before needing a replacement edge - but I'm already 2 seasons of snow use (well over 50 hours) and the concrete has not worn it down enough to replace as yet. I figure another full season before I buy a replacement edge to mount on the snow edge.
Just a different type of choice (ps. now the edge replacement pieces are available in 48, 54, and 60 inch lengths. I figure when I do get a new replacement edge it will be the 54 inch for my 48 inch bucket so I can guide the snow curl even better
