Abstract
A foldable hay rake has two rake arms comprised of first and second rake arm structures with rake wheels thereon pivotally secured to a base frame to pivot in a vertical plane. A center rake arm structure is pivotally associated with the base frame with a center rake arm frame located adjacent a rearward end of the base frame between the first and second rake arm structures. At least one of the hay rake wheels has a plurality of teeth extending therefrom with a tooth spacing between adjacent teeth of less than five inches and an outer diameter greater than 60 inches. A castor wheel is pivotally attached to the outer end of the main support frame, with an axle dampener operationally associated with the castor wheel to dampen wobbling of the castor wheel.
Claims32
A foldable hay rake, comprising,
- a base frame member having forward and rearward ends, and opposite sides,
- a pair of elongated wing arms having inner and outer ends with the inner ends being adjustably secured to the base frame and being adapted to swing outwardly with respect to the base frame,
- an elongated hay rake arm structure pivotally secured to the outer ends of the wing arms, and having a midsection and forward and rearward ends,
- a plurality of hay rake wheels secured to the hay rake arm structure,
- a main support frame having an inner and outer end with the inner end attached to the base frame,
- a center rake arm structure pivotally secured to the support frame about a turn rod such that the rake arm structure rotates in vertical spaced relation to the support frame and having a midsection and forward and rearward ends,
- a plurality of hay rake wheels secured to the center rake arm structure;
- and
- each wing arm being operatively connected by its outer end to a vertically disposed post connected to positioning wheels pivotally secured to the midsection of the hay rake arm structure.
A foldable hay rake, comprising,
- a base frame member having forward and rearward ends, and opposite sides,
- a first and second rake arm structure pivotally associated with the base frame with the first and second elongated hay rake arms located on opposite sides of the base frame member,
- a center rake arm structure pivotally associated with the base frame with the center rake arm located adjacent the rearward end of the base frame member between the first and second rake arm structures,
- a plurality of hay rake wheels secured to the first, second, and center rake arm structures,
- a main support frame having an inner and outer end with the inner end attached to the base frame, wherein the center rake arm structure is pivotally secured to the main support frame, and
- wherein an extension arm is attached to and extends transversely from the main support frame, a turn rod rotatably associates the center rake arm structure with the extension arm.
