A lid unit for a refuse compactor which includes a bin having a power-actuated compacting blade therein; the lid unit comprising a flat, dual-section lid supported on the bin in normally closing relation thereto, the lid embodying a front section and a rear section transversely hinged together at adjacent edges, the lid being longitudinally shiftable a limited distance on the bin to different selective positions, and instrumentalities provided between the lid and the bin arranged to prevent opening of either of the lid sections when the lid is in one position, to permit the front lid section only to be opened when the lid is in a second position, and to permit the rear lid section to be folded onto the front lid section and the folded-together sections then swung to depend in front of the bin when the lid is in a third position. The prevention of opening of either of the lid sections is for safety during operation of the compacting blade; the opening of only the front lid section is for the purpose of depositing refuse into the bin; and the folding of the lid sections and, as folded, their dependency in front of the bin is to allow the then open-top bin to be engaged and partially inverted for dumping into a hauling truck.
