  • WINDROW MERGER AND PICKUP HEAD
    Publication number: 20190133040
    Abstract: A windrow merger includes heads having cams that control the speed of the tines. The cam is configured with a section that slows the speed of the tines while passing a lower front portion of the path of rotation to lift material from the ground at lower speeds and therefore handles the material more gently at the point of pickup. The cam is configured to accelerate the tines at the point where the lifted material is propelled rearward from the pickup assembly. The merger heads also include a widened conveyor that is configured with an upper surface extending rearward and slightly downward to further evenly distribute material across the width of the conveyor. The heads are supported on skids that have a linkage connecting the skids at each end of the head with one of the skids having a mechanism that acts as a master to control the slave of the linked opposite skid.
