The present invention relates to a compression spring assembly for a hay rake. The compression spring assembly has a rod that slidably receives a first stop, a compression spring, and a second stop. A limiter assembly is connected to the rod and has a limiting member that is received through a guide of a guide assembly that is connected to the rod. The guide encompasses the limiting member.

Windrow mergers employ one or more design features as described herein in connection with a suspension assembly that allows the pickup head to rise or fall relative to a frame of the merger. One feature maintains a substantially constant force or pressure between a pickup head of the merger and the terrain regardless of a height of the head. Another feature maintains a substantially constant hydraulic pressure in a hydraulic actuator that connects the pickup head to a frame assembly of the merger. Still another feature employs a hydraulic pump driven by a power takeoff (PTO) of the tractor to charge and discharge a hydraulic actuator arranged to raise and lower the pickup head of the merger between an upper limit and a lower limit.

The present invention is a rake, comprising a tongue assembly and a wheel assembly operably coupled to the tongue assembly and being rotationally shiftable relative to the tongue assembly and the wheel assembly mounting a pair of rake assemblies. Each of the pair of rake assemblies is disposable in a generally horizontal disposition when the rake is in a transport disposition, the generally horizontal disposition being effected in part by the rotational shifting of the wheel assembly when transitioning between a working disposition and the transport disposition. The present invention is further a method of disposing the aforementioned rake in the transport disposition.

A rake includes a frame and at least one arm assembly attached to the frame via an arm member. The arm assembly includes a main beam coupled to the arm member. The main beam includes a first member pivotally attached to a second member, and the angle between the first and second members is adjustable. The arm assembly further includes a first rake wheel unit connected to the first member and a second rake wheel unit connected to the second member. The arm assembly attaches to the frame such that in a work position, the first and second rake wheel units are disposed substantially horizontally extended with respect to frame, and in a transport position, the first and second rake wheel units are disposed substantially vertically above the frame.

A suspension system for rakes having at least one floating rake wheel has a hydraulic cylinder is used for both lift and suspension of the floating rake wheel. A hydraulic accumulator provides expansion room for hydraulic fluid to move in and out of the hydraulic cylinder during suspension.
摘要:
A crop rake system for controlling the location of tines on the rake, which may include a rotatable rotation framework with an axis of rotation; a plurality of tines mounted to the rotation framework radially outward from the axis of rotation of the rotation framework; and a plurality of tine dampeners mounted to the rotation framework radially outward from the axis of rotation of the rotation framework, the plurality tine dampeners being mounted relative to the plurality of tines such as to determine the depth at which the plurality of tines may penetrate into a ground surface. The invention also includes either separately or in combination, a means for contracting and transporting the rake system on roads and highways.
摘要:
A deployment spreader with two arms and an elbow member arrangement, optionally and preferably having a locking mechanism involving an overcenter arrangement of certain pivots, for deployment or retraction of a folding hay rake which is towable by a tractor. The hayrake rake has a primary towable frame with right and left secondary frames pivotally attached adjacent the rear of the primary frame. The deployment spreader assembly is pivotally attached to the primary and secondary frames for pivoting the secondary frame relative to the primary frame.

The present invention regards a rake trolley with adjustable working widths, suitable for three point hitch finger wheel hay rakes. The trolley includes a transverse frame member. A pair of rake arms are connected to a pair of movable heads or supports, and a raising and lowering assembly is interconnected between the frame member and each rake head. The raising and lowering assembly includes a linkage, with a connector member on each side of the linkage extending between the linkage and one of the rake heads. A hydraulic cylinder assembly is interconnected with the linkage for moving it between a first position in which the rake arms are pivoted to a lowered, or working position, and a second position in which the rake arms are pivoted to a raised, or transport, position. The connector members are adjustable in length, to accommodate connection of the rake heads to varying positions along the length of the frame member.
