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.
A haymaking machine comprising a mobile frame and at least one pair of tined rake members supported on said frame, said rake members having outwardly extending tines and being rotatable about corresponding upwardly extending axes, driving means connected to rotate said members in relatively opposite directions about said axes, whereby crop is passed between said members during operation, two crop feeders being mounted on said machine and comprising a forward pair of feeders located adjacent the front of said rake members relative to the normal direction of tavel and a vertical plane of symmetry of said machine that extends between the axes of rotation of said rake members, a further pair of feeders being positioned to the rear of said forward pair and each pair of feeders comprising downwardly extending crop guides that correspond to said rake members.
A haymaking machine comprising a mobile frame and at least one pair of tined rake members supported on said frame, said rake members having outwardly extending tines and being rotatable about corresponding upwardly extending axes to trace generally circular paths, driving means connected to rotate said members in relatively opposite directions about said axes, whereby crop is passed between said members during operation, two crop feeders being mounted on said machine adjacent the forward aspects of said rake members, said feeders being positioned between the axes of rotation of said rake members, when viewed in the direction of travel, and outside the forward portions of said paths to guide crop rearwardly, with respect to the normal direction of machine travel, to the tines of the rake members and between the axes of rotation of the rake members, said crop feeders normally extending in rearwardly convergent relationship with respect to the direction of travel.
A haymaking machine comprising a mobile frame and at least one pair of tined rake members supported on said frame, said rake members having outwardly extending tines and being rotatable about corresponding upwardly extending axes, driving means connected to rotate said members in relatively opposite direction about said axes, whereby crop is passed between said members during operation, two crop feeders being positioned between the axes of rotation of the rake members, when viewed in the direction of travel, and the tines of said rake members extending outwardly from the rotary axes to trace circular paths and pass close to one another, adjacent a vertical plane of symmetry of the machine which plane is located between said axes of rotation, said feeders corresponding to said rake members and located outside circular paths traced by the inner ends of the tines of the corresponding rake members.
