Adjustable trip mechanism for round baler

In a round baler having a main frame, a tailgate pivotally connected to said main frame, a bale forming chamber defined by inwardly facing surfaces of crop conveying means which includes a plurality of side by side belts trained around a series of transverse guide rolls mounted in said main frame and said tailgate, means for feeding crop material into said chamber, said bale forming chamber expanding from a bale starting position to a completed bale position as crop material is fed into said chamber and conveyed by said conveying means in a generally spiral path, a pair of take up arms rotatably mounted on said main frame, at least one additional transverse guide roll extending between said take up arms and about which additional guide roll said belts are also trained, a pair of levers connected to rotate with said take up arms, said levers have attached thereto resilient means for maintaining tension on said belts by urging said take up arms to the bale starting position as said bale forming chamber expands, apparatus for wrapping a formed bale of crop material with twine, and a system for automatically tripping said wrapping apparatus when the bale formed in said chamber attains a desired size, the improvement comprising

• a cable,
• means for affixing one end of said cable to the baler to prevent movement during operation and means for resiliently mounting the other end of said cable,
• means for moving said other end of said cable from a first position corresponding to said bale starting position of said chamber to a second position corresponding to said desired size of said bale in said chamber,
• a sliding member moveable toward and away from a tripping position for automatically tripping said twine wrapping apparatus, and
• adjustable means selectively attached to said other end of said cable to engage said sliding member and move it toward said tripping position under conditions where said other end of said cable is moving to said second position.
