ABSTRACT:
A U-shaped bale push bar straddles a discharge gate of a large round baler with opposite legs of the bar being respectively pivotally connected to a pair of support brackets which are secured to and project rearwardly alongside the discharge gate from upper rear locations of opposite sidewall sections forming a portion of the baler main frame. A pair of chains are coupled between forward locations of the gate and the legs of the push bar and serve as lost-motion connections that cause the push bar to extend and retract respectively in following relationship to opening and closing movements of the gate such that interference between the gate and a discharged bale is avoided. An over center spring assembly acts between the push bar and support brackets to bias the bar toward its retracted position when the gate is closed and to bias the push bar toward its extended position when the gate moves a small amount towards its open position a small amount beyond an intermediate position permitting discharge of a bale. A shock absorber assembly works against the energy of the over center spring assembly to prevent sudden motion of the push bar.
