ABSTRACT:
A rake includes a tube having a bore for engaging with a handle and having a puncture intersected with the bore. A number of tines are secured to the tube. A plate is engaged in the puncture, has an opening for engaging with the handle, and includes a knob. A spring may bias the plate to engage with the handle so as to secure the handle to the tube. The handle is disengaged from the plate when the plate is moved against the spring by the knob such that the handle may be easily adjusted to suitable position relative to the tube.
