ABSTRACT:
A liquid manure applicator comprises a tank for holding a supply of liquid manure that is distributed onto a farm field through a distributor having a plurality of distribution ports and hoses. The hoses lead to individual distribution tools that include a pair or rotary coulters and a bellows for applying downforce to the coulters. The distributor includes a ring that restricts the size of the solids entering the distribution ports and hoses to something substantially equal to or less than 50% of the cross-sectional area of the hoses. This prevents the hoses from plugging even when small diameter hoses are used to lower the application rates to values more consistent with the needs of a zone tilled field. A rotary chopper in the distributor reduces the size of larger solids until they have been broken up into pieces small enough to pass the restriction provided by the ring.
