My grandfather used to always use the blade on his tractor. But my father has been using a snowblower attachment for many years. With a blade, you have to be more careful that you don't let snow build up for a long period. Otherwise, it'll be a very slow process to clean the laneway.
Our old Ferguson TO-35 still pushes the old snowblower every winter.
A neighbour used to use a combo of bucket and blade to do his driveway... but 95% of the time we were over there with the tractor and blower doing his driveway, just because thats what we did. If we were away for a few days, or if he wanted to touch up around the edges, he'd use the bucket and blade. Problem with that method is you end up with a lot of gravel on the lawn... he did our driveway a couple times one winter when my Father was away on a trip and I was only home on weekends. He kept the driveway clear, and come spring, we got to rake all the gravel off the lawn. hehe.
