摘要： A machine is provided which is mountable on another vehicle for effecting the pneumatic spreading of granular material along a working direction. The machine is of the type that has a central hopper divided in its lower area by a roof shaped middle part disposed in the working direction into two sections which have outlet openings and a metering device driven through a regulating drive which is receptive of material from the outlet openings. Tubes are provided which are receptive of material from the metering device and have a portion overreaching the hopper transversely of the working direction and discharge openings at the outer extremities thereof exposed at intervals from one another transversely of the working direction. A blower is situated forward of the machine and has an impeller shaft which is driveable by the powered take up shaft of the vehicle pulling the machine. An air duct connects the blower to the tube. In order to obtain a compact construction, the blower has the front walls thereof disposed behind the front wall of the hopper and the impeller shaft is mounted at the rear end of the hopper and is driven from the power take off shaft of the vehicle pulling the machine by a shaft disposed underneath the roof shaped middle part of the hopper.
