ABSTRACT:
A gardening rake useful for raking leaves, garden refuse and the like, has a pair of parallel rows of rake tines disposed in a U-channel rake header. The pair of parallel rows of rake tines are formed of multiple tine pairs of spring metal strips formed in a U-shape, and secured at the tine pair U-base to a single common tine frame support. The tine frame support has a handle means useful for adjusting and adapting the length of the flexible spring metal tines to the desired overall spring stiffness for a specific raking operation.
