ABSTRACT:
A single constant displacement pump provides lubricant under pressure from an on-board grease reservoir through a two-position valve to a selected group of distribution manifolds mounted on a cotton harvester. Each manifold of the group is connected to a plurality of conduits which lead to harvester row unit lubrication points, such as on the picker bar cam tracks, picker drum drive gears and the lubricant cavity for each of the picker drums. A line from the picker drum cavity opens into and lubricates the drum thrust washer area. The quantity of lubricant to each point is determined primarily by relative conduit resistance, which in turn is controlled by conduit length and cross section so that individual metering valves or pumps for each lubrication point are obviated. Conduits of substantially equal length and cross section are provided for each group of points which are to receive equal amounts of lubricant. Two groups of manifolds are provided for each pair of row units and are charged, in turn, with lubricant under control of the selector valve.
