Go get something like this for $10 in Home Depot, made in USA, light and efficient - thanking to the 30" width and foam handle. Tines never get clogged; in case they did, a light shake cleans them all. Plastic and flexible tines are friendly to concrete sidewalk. Within few minutes, wife's command fulfilled, easily and beautifully, regardless how large your lawn is, and you still have lots of energy left for the happy night.
Never waste money on something like this:

With such a wrong rake, you'll work a whole day and still cannot get any job done.
See how well the $10 rake works:
