Abstract: A device for applying night-visible road markings includes a material hopper, a floor gate, a pair of side runners and a plurality of vertically oriented shutters. When the floor gate is moved away from an outlet extending through a bottom side of the hopper, marking material flows from the hopper, through the outlet and onto the surface of a road.

Abstract: Straw spreaders are normally controlled manually by the operator and it is therefore extremely difficulty to continually adjust the speed of the spreader so that the straw layer is reasonably even because the density of the straw varies continuously across the average field. The present device includes a rheostat sensor at the straw walker that controls the speed of the orbital motor driving the spreader blade assemblies. This results in a relatively even spread of straw taking place regardless of the variation in straw density as the motor slows down under a light load and speeds up when heavy straw is encountered. The operator can, of course, control the on/off functions from the cab if, for example, it is desired to spread alternate swaths.

Abstract: Two spreading mechanisms disposed substantially completely across a rear outlet of a container-hopper having a movable deck, the spreader comprising a pair of two-part distribution members which rotate about vertical shafts which are disposed close to the edge of the deck.

On the same shaft the lower part is a disc type ejector extending in substantial part under the moving deck to receive fertilizer which the tines miss. A freely rotatable guide member surrounds the shaft between the ejector and the tined portion to preclude material from winding around the shaft.
