A hopper for moving and accurately placing granular materials and granular slurries. The hopper comprises: an elongate feed trough having two opposite end portions and an open top side portion so that the trough may be filled along the open top side portion; an elongate auger having flexible blades, to facilitate non-jamming operation, positioned in and extending along a bottom portion of the trough, said auger having a drive and a floating discharge end portion; a drive positioned adjacent to one end portion of the trough and releasably connected the drive end portion of the auger; a discharge sleeve positioned in the other end portion of the trough encircling the other floating discharge end portion of the auger. The trough may be lifted from a long side portion thereof with the loader so that the center of gravity of the trough is closely adjacent to the loader, enabling a small loader to lift an adequately large payload, and enabling an operator thereof to view, meter, and accurately position the discharge end of the auger. In the preferred embodiment the auger is driven by a hydraulic pump. The trough hopper has dramatically reduced labor required to transport and pour mixed cement or other materials in tight and elevated places.
