Shovel is more than enough, but if she's dead set of getting a blower then she might want to check out the one of those little itty bitty Toro
2-strokes blowers. Light enough for anyone to handle.But she'll pay prime for any blower in the winter time. Best time to get a blower is in the non-white months.
