Abstract:
A multi-row root-crop harvester attachable to a tractor, which harvester has linkage for independent vertical movement of at least two digger/shaker/inverter assemblies for digging root-crop vines from the ground in a field, shaking dirt from the vine roots, and inverting the root-crop vines for exposing the peanuts to air, comprising:an elongated first tool bar for attachment to a tractor for pulling at least a pair of digger/shaker/inverter assemblies through a root-crop field to be harvested;at least two elongated second tool bars, each attached to a separate respective one of the digger/shaker/inverter assemblies; andat least a pair of linkages, each connected between the first tool bar and a respective one of the second tool bars;each linkage comprising:a pair of A-frame assemblies, a first one of the pair attached to the first tool bar and a second one of the pair attached to one of the second tool bars; anda cross-member pivotally connected at distal ends to the pair of A-frames,whereby the digger/shaker/inverter assemblies, being attached to separate second tool bars connected by the linkages to the tool bar on a tractor, move vertically independently of the other such digger/shaker/inverter assembly as the tractor pulls the digger/shaker/inverter assemblies through the root-crop field to be harvested.
