ABSTRACT:
A lawn debris collection box is mounted, by a slide member, for movement along upwardly and rearwardly inclined guide rods. The box is also mounted so as to pivot upwardly and rearwardly about a connection with the slide member. Also mounted to the slide member for upward and rearward pivotal motion is a pair of drive arms which each have a lost motion connection with the box. A latch arm operative for releasably retaining a hinged lid of the box in a closed position is pivotally connected to the drive arms along with a pair of lift actuators which drive and latch arms to first release the lid, to raise the box until the slide members engage stops at the upper ends of the guide rods and to thus pivot the box to a dump position.
