Abstract
An apparatus for collecting litter from roadways and grounds includes a ground engageable rotating drum with easily removable and replaceable fingers which slip in and out of channels mounted on the drum. A spring finger assembly rotates against the drum to aid in litter pickup and to strip material from the drum and deposit same on a conveyor. The conveyor directs the litter into a hopper, which, when full, is lifted by an arrangement of pivots and linkage arms to raise upwardly, then swing rearwardly and tip to dump the litter into a suitable receptacle.
