Abstract
A haymaking machine has a pair of rotatable rake members that are driven to turn in relative opposite directions about upwardly extending axes, towards one another to pass crop between them. Outwardly extending tines on the rake members define circular paths that intersect or are closely adjacent one another during operation. Beginning at the front of the rake members, with respect to the normal direction of travel, a pair of crop feeders are positioned to guide crop between the rake members and towards the intersecting paths of their tines. The feeders comprise downwardly extending elements that can be curved or configured to shed crop adjacent the ground, near the rotating tines. Further feeders of similar structure are positioned to the rear of the forward pair but within the paths traced by the tines, when viewed in plan. The feeders can be adjustable in a vertical direction and/or deflectable against spring opposition to accommodate heavy crop. The feeders can be a screen or a row of resilient rods or wheels with teeth, any of which can be pivoted to the machine frame.
