What is this little rake? IMO, it is a mostly useless tool. Landscape rakes have spring steel tines that do not bend like the ones on this example. Most landscape rakes are designed to mount on a three point hitch so that they can be lifted at the end of a pass and then lowered when they are in position for the next pass. This unit is a drag style implement.
Once you start using it, you will quickly realize how useless it is. The primary purpose is to gather up debris and shift that debris to a pile where it can be loaded up and taken elsewhere. In order to do this efficiently, you must be able to swing the rake left and right of centre to one of 2 or 3 fixed positions. This will allow you to begin with a pass down the middle of the area and then make alternating passes to each half of the area to allow the rake to windrow the debris to the edges of the area. This rake does not seem to have any provision for angling.
Another task is to level out loose soil by picking up the high spots and dropping them in the low spots. The better landscape rakes have adjustable trailing wheels that help to establish a grade for the area being worked. Make passes north to south progressively and then switch to east/west passes in order to end up with a fairly level surface that will then be ready for seeding. Ground engaging tools need to have WEIGHT to them or they simply will not function as intended. Manufacturers of lawn tractors were prone to offering aftermarket attachments like this one in order to make their lightweight lawn cutter look like a garden tractor.
