I've been considering a snow bucket myself. Pusher wouldn't work for me. I use the rear blade for light stuff, but over about 4-6" at a time it's over matched. During heavy snows I try to get out often, but even staying on top of it, the drifting is a killer. I have a 3pt blower, but going backwards and very slowly at that is not my idea of a fun time.
I've been looking at various buckets out there, and most designed for skid steers are just too heavy for my NH Workmaster 40. There is one, made lighter, at around 400 pounds for a 72 inch I think, that might work for me.
I already have edge tamers on my bucket and would definitely use them with a snow bucket. All my plowing is on dirt and gravel so I don't worry too much about hitting stuff. In fact, once there is a solid ice/snow pack on the road, the road is as smooth as it gets, and plowing is actually easier.. Still, the edge tamers stop any digging in, and with a lightly built snow bucket, digging in could seriously bend the thing.
The other fly in the ointment is the snow sticking to the bucket. I have had good luck with turtle wax spray wax on the inside of the bucket, but am going to try stuff called REJEX this year. It seems to be a nice, slick, hard finish, but time will tell. Will have to put it on when done with moving dirt and stuff around. Rejex is more expensive than the Turtle Wax, but you don't need as much of it, and it certainly gives a slick feel.
