I think hydraulic chute control is worth every cent, especially if you've already got rear hydraulics. I use a blower around buildings, between buildings and vehicles and at a highway entrance. I use the chute control a lot, and often for fairly small adjustments. A lot of care does have to be taken when operating a blower near a highway to keep the flume from blowing across traffic.
It looks like you may have an area that's wider than a blower will throw. If so, you'll probably come up with a technique for clearing the area. However, blowing snow that's already been blown isn't a great solution. Some ways of doing it would require many chute adjustments. A hydraulic chute might be a real good idea.
Since I don't have a blade, I do use the loader for removing snow-pack that builds up. What works for me is to float the lift with the bucket angled slightly down. The bucket can be flattened if the bite is too deep or the bucket hangs on uneven ground. I go slow enough so that if the bucket hangs, my turf tires break loose and nothing breaks. Sometimes less traction is good. That technique may still leave some snow pack. If I want to remove more, I angle the bucket down hold down pressure until the front wheels start to lift and then back-drag the bucket.
As a couple of comments indicated, think about clothing if you don't have a cab. I become 100% snow-coated when the wind is from some directions.
Hope you're happy with a 3ph blower, and I think we're getting what's left of your snow today--starting out with freezing rain, yeeach!
