Abstract

The towed spreader and filter for liquid manure has an easily rechargeable filter bed of loosely packed material housed in the base of the unit. The hollow drainage cylinder (1) houses the filter material and is cut away at its back end to take a rotating plastics sleeve which opens and closes regulating flow. A wide but slender pipe (2) houses the liquid sewage and an agitator (17), while hydraulic or electric motors (7) with chain (8) and pulley (9) open trap (5) allowing filter material to be changed, and the unit is pulled and supported by a tractor unit.
