thanks for all the questions / concerns. Most of these pusher boxes have spring trips and the ones I am considering do. Right now I use my bucket in float mode and will do so with the box as well. All the parking lots that i do are level and paved. I find that i usually do a "running" start to get piles of snow moving anyway.
As far as lifting with it: I've seen guys stack snow just like a plow truck with a box. Just by lifting and pushing, like you mentioned. If not, it would not be hard to take it off and use the bucket for stacking. I'm considering both the models that attach to the existing bucket and the ones that are quick tach. i also find that when I'm getting near the edge of parking lots and have a large mound of snow, I flip on the snow blower and blow it into hills much higher than I could ever stack with the bucket.
For backblading in corners I use my INVERSE blower with backdrag attachment. (will post pics real soon)
Good point about the summer work with a blade.
I have considered a blade too, but am concerned with the amount of spillage from the sides. The boxes seem to move the most amount of snow and clean up a parking lot the fastest.
You do see a lot of pusher boxes on front end loaders, skid steers and really large tractors and I just wanted to make sure it is going to be practical on my little tractor before I spent the dollars.
Thanks for the suggestions.
