An indicator mechanism for visually displaying the full condition of a lawn mower grass collection bag, specially adapted for use on a riding lawn mower having a rear mounted bag. The indicator mechanism comprises a housing mounted to the discharge chute leading from the mower cutting deck to the collection bag, in a position visible to the driver during normal cutting operation of the mower. The housing includes a compartment in communication with the interior of the discharge duct through a suitable opening. An indicating member is hingedly disposed within the housing and is movable between a lowered position and a raised position in response to pressure variations caused by changes in the air flow within the duct. When the collection bag becomes full, high pressure within the duct forces the indicating member to its raised position, where it is visible to the driver through a window formed in the side of the housing.
