I tend to use tarps when it's not too hot, saves a lot of raking. When the mess is extensive, tarps are magical. If the mess is minimal, its more worth it to leave the tarps alone and just rake.
I hate raking. Hate it worse than anything. Gross misappropriation of talent. I favor a backpack blower that's rated at least 220 MPH. If you have one guy on rake, and one guy on blower, in synch, and working together as a team, the blower can multiply the rakers efforts, and vice versa, and the two can clean-sweep large areas of drop-zone with amazing swiftness. Raker guy should decide where the raking's going to happen, and blower guy just stay tight with him.
In an era long ago, I used the widest plastic rakes I could find. I took adhesive-backed aluminum tape (duct tape can be used, but it doesn't last as long). Tape across all the slots between the tines, all the way to where the teeth curve. Tape BOTH sides, so you get adhesive-to-adhesive contact. Then, with someone driving 10-20 mph, you drag those teeth on the pavement for a block or so, at the approximate angle that you generally rake at. This 'adjusts' the teeth so that when you rake, all the teeth get a consistent bite.
This rake now serves multiple purposes: sawdust and fines carrier, sidewalk swoosher and I remember it working really well as advertisement. People were intrigued with these rakes and I got a lot of comments, and then they'd hire me.
These days I'm back to those that Brian describes. I stow my rakes vertically on my chipper, and I tend to drop limbage as close as possible, which means sometimes the chipper gets whacked (i.e the rakes get whacked. With the metal ones, you just bend em back. With the plastic ones that you've sunk a half-hour into creating, iss not so good. -TM-
