If you get more than the occasional couple of inches, you want a blower unless you only have a short driveway or area to clear. Each time you plow snow, it piles up on each side and pretty soon you can't pile anymore. It you blow the snow, you spread it away and over a greater area, so you can pretty much deal with any snowfall.
A blade is great for dressing things up, or dealing with the odd drifting snow.
Using a blade or FEL to move a lot of snow can take an awful lot of time, and wear and tear on the tractor. My 3010 with a rear blower is a faster snow mover than my old 580C with a 6' bucket. And it makes a better job.
I am not directly familiar with the
BX1500, but I suspect that if you get a 48" rear blower it'll handle it because the attachment would meet the weight and power requirements of the PTO and hitch.
I have a Deere 345 with an 18 hp gas engine and a belt driven 40" front thrower (single stage) and it works ok, except on real heavy wet snow, so a diesle with a PTO should work fine.
I have a lot of trouble with a rear mount because of my back, though.
