Abstract
A hay conditioner is provided with a crop deflecting baffle having an operative position for deflecting crops for deposit in a swath. Rearwardly converging deflector vanes are mounted on the baffle, preferably about halfway respectively between the transverse edges of the baffle and the center of the crop stream. Preferably, the angle of convergence of the vanes is less than that of the fixed side deflectors of the preferred windrowing apparatus.
Claims8
A hay harvesting machine of the type including a frame, a transversely elongated crop cutting apparatus disposed forwardly on said frame, a pair of transverse outer counterrotating hay conditioning rolls disposed on said frame rearwardly of said cutting apparatus, said rolls being closely spaced for receiving cut crop therebetween and propelling it in a rearwardly directed airborne stream, windrowing means disposed rearwardly of said conditioning rolls for receiving said airborne stream and effecting a lateral consolidation thereof for deposit on the ground in a windrow, a transversely extending crop deflecting baffle mounted to said frame rearwardly of said rolls and having a first position located generally above said airborne stream thereby permitting substantial consolidation by said windrowing means and a second position intercepting said stream and deflecting it downwardly for deposit in a swath, and deflector vanes disposed on the laterally intermediate portions of said baffle, said vanes being disposed at an angle to the crop stream to deflect crops toward the center of said stream.
A hay harvesting machine including a transverse frame, a crop cutting apparatus disposed across the front of the frame, a pair of counterrotating hay conditioning rolls disposed rearwardly of said cutting apparatus on said frame for receiving crops therefrom and propelling said crops in a rearwardly directed airborne stream, windrowing apparatus disposed on said frame rearwardly of said conditioning rolls and including a pair of rearwardly converging fixed side deflectors for laterally consolidating said crops for deposit on the ground in a windrow, a trapezoidal crop deflecting baffle having a forward edge hinged to said frame above the crop stream adjacent the forward portion of said side deflectors, means for controlling the position of the rear edge of said baffle between a first position permitting substantial consolidation by said windrowing apparatus and a second position intercepting the crop stream at an oblique angle and deflecting it downwardly for deposit in a swath of substantially greater width than a windrow, and a pair of rearwardly converging deflecting vanes disposed on the cropward side of said baffle respectively on either side of the longitudinal center line of said windrowing apparatus.
