Abstract
A liquid manure spreader has a tank, and a filler opening in the top of the tank is defined by two parallel sidewalls and two connecting walls which extend a substantial distance into the tank. A pair of opposed filler doors are pivoted on the parallel sidewalls a substantial distance below the tops of the walls and are lightly biased to transverse positions in which they abut substantially on the median plane between the sidewalls to close the filler opening. The biasing is light enough that the doors swing downwardly to an open position when liquid is discharged onto them from a filler hose.
