Should be no problem in the snow. Only issue I see is would be in dirt and maybe not enough traction to cut the full width. But with snow, it is easier pushing/pulling, and you can always take smaller bites. Heck, I have a 700lb 7' blade on my little ole L3400 and manage just fine:thumbsup:
Another caution, on cheaper made blades of longer widths, sometimes the frame isnt made in a way that will allow the blade to spin around 180 degrees without hitting the tires. That can be a PITA cause the only way to spin it around then is to unhook, then spin, then re-hook up. Maybe something to look into before you make a decision.
You will tear up more stuff in the snow because you are pushing backwards and can't see.
