A concave assembly for an agricultural combine harvester comprises a concave, a cover, and a cover actuator. The concave comprises a grate. The cover has an opened position uncovering at least a portion of the grate to allow crop flow through the at least the portion of the grate and a closed position covering the at least the portion of the grate to block crop flow through the at least the portion of the grate. The cover actuator comprises a four-bar linkage and moves the cover between the opened position and the closed position.

A fluid line connection for a manifold of a pneumatic distribution system for an agricultural air seeder. The fluid line connection has a male connector extending from the manifold and a plurality of threads on an exterior surface, a fitting connector configured to retain a primary tube thereon, the fitting connector defining a lip, and a locking ring having a plurality of threads and a receiving portion on an interior surface, the receiving portion configured to receive the lip to retain the fitting connector with the locking ring, and the plurality of threads of the locking ring configured to engage the plurality of threads on the male connector. The fitting connector is removable from the male connector by disengaging the locking ring without requiring axial movement of the fitting connector.

Quick disconnect conveyance tubes

An extractor is disclosed for a sugarcane harvester that chops stalks of sugarcane into billets. The extractor comprises a housing, a fan positioned within the housing and comprising fan blades mounted for rotation in a rotational path about an axis of rotation to induce a flow of air to extract leaf material from billets produced by the sugarcane harvester, and a leaf shredder positioned within the housing and comprising shredding knives fixed against rotation about the axis of rotation, the shredding knives offset axially from the fan blades relative to the axis of rotation in proximity to the rotational path of the fan blades such that the fan blades and the shredding knives cooperate to shred leaf material by shearing action as the fan blades rotate past the shredding knives about the axis of rotation.

A fluid line connection for a pneumatic distribution system for an agricultural air seeder includes a female connector having an inside diameter with a groove and a male connector configured for internal assembly with the female connector. The male connector has an external tab that engages the groove to retain the male connector to the female connector when the female connector is rotatingly assembled with the male connector. The female connector is removed by rotating and disassembling from the male connector to access a conveyance tube or manifold for servicing these parts. A sealing member is assembled between the male and female connectors to form a fluid seal. A primary tube can be assembled between two fluid line connections to form a quick connect assembly. A fitting connector and a locking ring are assembled with a fluid line connection to retain a primary tube thereon for an air drill.
