The present disclosure relates to a lawn sweeper designed to collect debris, such as grass clippings and leaves, from a surface such as a lawn, and more particularly to a lawn sweeper with a tilt-able hopper frame and hopper bag that includes a handle such that an operator may tilt the hopper frame and hopper bag, using the handle, to empty the hopper bag contents. The hopper bag and hopper frame are connected to a lawn sweeper unit using a hopper rod which is inserted into two slots at the ends of two hopper support bars and secured within the slots by two corresponding latch plates, one latch plate at each end of the two hopper support bars. The latching mechanism allows the hopper frame and hopper bag to be easily removed from the lawn sweeper unit for storage.
