I wouldn't use it for a few reasons, first of all I think it is easy to get the proper angle of a bucket for plowing or scooping dirt, second with these on the bucket they don't allow the cutting edge to scrape the ground down to the hard surface, they will hold the edge up off the ground always leaving that thickness of snow behind which will eventually get packed into glare ice and will also amount to a slushy sloppy mess in the spring when it starts to thaw, Third reason is it makes it impossible to backblade anything, when pushing snow around buildings and other objects around your yard it is often times necessary to pull the snow away from something in order to push it or scoop it away. These things are a gimmick item that is unnecessary you would be better served to get practice setting the proper angle, you will be much more proficient with the loader in the long run.
The way I set the angle most easily is to put the loader in float so the bucket sets on the ground, then with the loader floating adjust the angle of the bucket, you can tell by watching the bottom of the back of the bucket when it is in it's flattest position, then angle the front down ever so slightly ad more angle if required to scrape down how you like. You can also feel the difference when the loader is in float and you rock the bucket to the flat position.
