Abstract
In a manure spreader for handling slurry material, an auger is mounted in the bottom of a tank and an expeller is disposed at an opening in the tank to discharge material therefrom. A drive system is provided to rotate the auger and the expeller in different directions when the drive system is connected to a tractor PTO. the drive system includes a series of drive members such as chains and sprockets arranged and connected to cause rotation of the expeller in the same direction as the tractor PTO and rotation of the auger in the opposite direction at a substantially slower speed than the expeller.
