I use this Grattex Model 559 on my B26 and it works great. It is extendible from 5.5' to 9' and does a great job of back blading in reverse for those corner areas.
I have only had light snow falls this year but the B26 will push this blade pretty fully up the slight slope I have. If it gets too much, I just narrow the blade and take it in smaller chunks. This blade has cut my driveway clearing time in half.
I had an old 8' angle blade from my Suburban but my dealer did not recommend it as he was concerned it could bend the loader arms. The Grattex blade with the closed gables pushes more snow for me and I don't have to deal with winrows. I have a large open area near my garage and I find it much fast to clear with this type of blade.
