Profile: Hollowell Products Co. offers elephant-vac model mobile litter vacuum equipment. Our EVC-4H hydraulic litter vacuum sucks up litter as the operator drives along, directing the vacuum hose to pick up scattered litter strewn against or in fences, under trees, around bushes and along curbs, as well as in wide open spaces. The hydrostatic vehicle drive enables the operator to maneuver the vehicle fore and back with a single foot pedal. The vacuum hose is mounted on a balanced spring-boom for easy side to side and up and down movement.
