I use the largest Craftsman lawn sweeper (42 or 48 inch, I'm not sure) to pick up needles, cones, twigs and even large sticks. It does a great job. When I mow, I put the deck on mulch which helps grind the needles smaller and at the same time drag the sweeper behind. This removes the needles, cones and twigs so well that I can mulch without the sweeper on the next cut. I even use the sweeper to sweep up the straw off of my driveway. Of course if your yard is not very even the sweeper may not work as well. So, if in doubt,rent or borrow one first to see how it works on your lawn. The only downside is when the lawn is heavy with straw (large yard 2 acres with 30 pine trees) I am constantly making trips to the back field to dump pine straw. This problem is not so bad in the spring and summer unless a storm or wind comes through.
