Abstract
A machine (20) for laying a film on a landfill surface and depositing an anchoring material such as soil on the film is carried on the blade (22) of a bulldozer (24). The machine (20) has a pair of hoppers (28, 30) with an engine compartment (38) between them. The front walls (40) of the hoppers have exit slots (52) for the release of anchoring material onto the film as it is being laid. The hoppers have chain floors (62) for moving the anchoring material to the exit slots (52). A film roll holder 32 below the hoppers holds a roll (82) of film for unwinding onto the landfill surface as the machine is propelled.
