The most useful lawnmower attachments depend on what the owner uses it for. People who live in areas that experience a lot of snow can find snowblower attachments useful, while those who want to keep their lawn as neat as possible might want a bagger attachment.
For people who want to keep a large area of grass looking full and lush, a pull-behind broadcast spreader helps to distribute fertilizer, insecticide and extra grass seed. An aerator attachment is also useful for those who don't want to rent a separate machine when the lawn needs this type of care. For people who use their riding lawnmowers as part of their farm equipment, an attachment that plows or tills is also useful.
