ABSTRACT:
A manure transfer and storage system (2, 102) includes a manure collection hopper (13) disposed at a first location for receiving manure. A pull pump is operatively mounted in the collection hopper (13) and includes a movable piston body (30, 130) which is cooperable with a cylinder (27) for pumping manure from the collection hopper (13) into cylinder (27). Cylinder (27) is connected to a manure transfer pipe (25, 26) for transferring manure to the second remote storage location. In the first embodiment, piston body (30) telescopically slides over cylinder (27) in a straight line motion. In another embodiment, the piston body (130) is pivotably mounted in collection hopper (13) for arcuate rotation about a pivot axis (134). Piston body (130) includes an arcuate manure confining surface (136) which engages the cylinder (27) only along a single line (144).
