  • Patent number: 8381503
    Abstract: An improved crop pickup apparatus for a round baler in which the pickup apparatus substantially wider than the bale chamber inlet opening. The pickup apparatus includes a transversely aligned, overshot crop feed rotor positioned longitudinally between the forwardly disposed pickup tine reel and the rearwardly disposed floor roll. The feed rotor comprises a plurality of generally radially extending feed fingers that intermesh with a plurality of circumferential grooves on the floor roll and tines on the tine reel thereby enabling the spacing between the rotational axes of the floor roll, tine reel, and feed rotor to be reduced compared to a non-intermeshing arrangement. The intermeshed relationship also strips crop from the feed rotor without the use of a separate crop stripping device. The feed rotor further comprises a pair of tapered feed augers arranged on the feed rotor rotational axis positioned outboard of the inlet opening.

  • Patent number: 8359987
    Abstract: A disc hub assembly includes a shouldered spindle that is secured to a disc opener frame and to which a depth adjustment arm and a gauge wheel arm are connected. The disc hub, to which a ground opener disc is mounted, is disposed on the spindle in a manner that allows the disc to rotate around the spindle. A gauge wheel is connected to the gauge wheel arm. When the depth adjustment arm is rotated between depth setting positions the gauge wheel arm is also rotated. As the gauge wheel is connected to the gauge wheel arm, rotation of the gauge wheel arm causes rotation of the gauge wheel. The depth adjustment arm is spring biased into engagement with an arc of notches on the disc opener frame. The notches define a range of positions at which the depth adjustment arm may be positioned.
