Abstract: A haymaking machine has two side-by-side rake wheels that are driven to rotate about upwardly extending axes and move crop between the wheels. Converging guide walls of horizontal rods are positioned in front of the rake wheels and some of the rods extend rearwardly to intersect the working paths of the wheels. Preferably the walls are located above the wheels. Each wheel has arms pivoted to a central portion and groups of tines are pivoted to the outer ends of the arms to turn about horizontal axes. Each group of tines is mounted on a carrier by coils that surround a tube so that the coils can be turned relative to the tube about a vertical axis and set in swath or tedding positions. Swath guides can be positioned at the rear of the rake wheels.

Abstract: A haymaking machine for the tedding and windrowing of fodder, comprises a pair of rake wheels driven in rotation on which working tool carrier arms extend outwardly and are mounted for pivoting in support bearings articulatedly connected to a drive hub. Each of these arms has at its end adjacent the axis of rotation of the corresponding rake wheel, a control crank having a roller thereon. The roller rolls on one of two guide tracks. The inner guide track is for windrowing and the outer guide track is for tedding. The arms occupy a relatively raised position and the axes of rotation of the wheels are tipped forward during tedding; while the arms occupy a relatively lowered position and the axes of rotation of the wheels are substantially upright during windrowing.

Abstract: In a haymaking machine having two staggered rotors with substantially vertical axes, the tine groups on the circumference of the rotors each comprise one or more fixed upper tines and one lower tine which can yield upwardly. Preferably, the number of tine groups of the forward rotor is one half the number of tine groups of the rearward rotor and there is a single, upwardly yielding tine between every two successive tine groups of the forward rotor. Preferably, the tines extend through slots in a closed cap.

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.

Abstract: A hay-making machine having rakes supported on a frame for rotation about a generally vertical axis. The tines of the rotary rake are secured on tine carrier arms which extend outwardly from an axis of rotation for the rotary rake and are rotatable with the tine carrier arm about the longitudinal axis therefor. A control lever is mounted on the inner end of the tine carrier arms. A cam roller is mounted on the control lever and engages a cam pathway mounted on the frame of the machine. The tines on the tine carrier arm are secured to a tine carrier part which is pivotal relative to the tine carrier arm about an axis perpendicular to the longitudinal axis of the tine carrier arm. The pivoting action of the tine carrier part facilitates a reversal of the tines to further facilitate a movement of the rotary rake in an opposite direction of rotation about the generally vertical axis of rotation. A locking mechanism is provided to secure the tine carrier part in two positions spaced approximately 180.degree.

Abstract: A haymaking machine for the tedding and windrowing of fodder comprises a pair of rake wheels driven in rotation, with working tool-carrier arms mounted pivotally in support bearings thereon and having at their ends facing the rotation axis of the corresponding rake wheel, a control crank that has a roller that moves in a guide cam so as to cause the working tools to pivot over a portion of their path of revolution, upward and in the direction opposite to the direction of rotation of the corresponding rake wheel during windrowing. The control cranks are connected with the working tool-carrier arms by means of an articulation, the angle formed between the geometric axes of the control cranks and the geometric axes of the working tool-carrier arms, as seen from above, varying when the carrier arms are transposed from the windrowing position into the tedding position and vice versa.

Abstract: An agricultural implement for tedding, swath turning, hay collecting and similar operations. It comprises four rotors which rotate almost parallel to the ground and each of which carries series of outwardly directed tines. The four rotors may be alined transverse to the direction of motion, or they may be arranged according to a forwardly opening V or they may be arranged in a transport position in which the outer rotors are positioned practically in front of the inner rotors. Seen at the front of the implement, the two outer rotors always rotate toward one another, but the two inner rotors rotate away from one another in their first position and toward one another in their second position. This is obtained by swinging the pair of inner rotors over 180.degree. about a central, common pivot. The frame comprises a rearwardly extending main frame beam, a reversible cross beam at its rear end carrying the inner pair of rotors and a pair of adjustable side arms carrying the outer rotors.

Abstract: Hay-raking machine having a plurality of raking means rotatable on vertical axes. The invention relates to the type of hay rake having a plurality, as four, vertically rotatable raking devices supported by ground wheels and connectible to a tractor, as by a conventional three-point attachment means. Frame structure for supporting said raking devices provides for convenient and efficient positioning by an operator without his leaving the tractor seat for adjusting the raking means through a plurality of desired operating positions as well as for moving the raking means into an appropriately compact position for transport of same. Positive drive means are provided for driving from the power output shaft of the tractor for driving said rakes, same being arranged, however, so as to not inhibit moving said rakes into a compact body for transport purposes and at the same time when said rakes are so positioned, to terminate the driving thereof.

Abstract: A raking machine that displaces crop lying on the ground has at least one, preferably two, raking members that rotate on upwardly extending axes. Each raking member has a felly-like or circular member around which tines or other crop gathering elements are displaceably mounted. The circular member can be a cylindrical or conical wall that is deformable or flexible during rotation so that tines secured by pivots or bolts near the bottom of the member can move in axial, radial or tangential directions responsive to ground undulations and/or control means, allowing crop to be deposited in a swath or at a predetermined point along the circumference of the raking member. The circular member can be foldable responsive to the control which can be driven along a track and unfolded to deposit crop as desired. Also, side-by-side raking members can have tines pivoted in assemblies in which crank arms are contacted by control means or elements on an adjacent rake wheel to turn the tines and deposit crop.

Abstract: A haymaking machine has at least one rake member mounted for rotation about an upwardly extending axis. Tines or groups of tines are supported around the circumference of the rake member on corresponding means that enables the tines to move up and down with respect to a central portion, independently of other tines supported on adjacent means. In one version, groups of tines are supported at the ends of outwardly extending arms which are pivoted to the central portion. The tines can be mounted with a ground engaging wall segment which subtends an angle of the rake member's circumference. Also the tines, or rake member as a whole, can be mounted on a shaft that is journalled at an angle in a ground engaging spherical wheel. In another version, the tines can be mounted on an elongated support element that is interconnected to the central portion and an adjustable ring on that portion, with chains that permit the tines to move vertically and radially with respect to the central portion.

Abstract: A hay-making machine has at least one rake member rotatable about an upwardly directed axis of rotation and comprising tines, which are outwardly pivotable by centrifugal forces exerted during rotation of the rake member.The tines convert from a working position and a transport position or conversely solely by centrifugal force and their own weight without the need for using spring means. According to the invention the tines are pivotable into a transport position only by means of their dead weight.

Abstract: A hay making machine has a rake that rotates on an upwardly extending axis and an outer circumference defined by a felly or rim to which elongated crop working elements are connected. The elements can be tines or flexible strips that are pivotally or flexibly associated with the felly or rim so that the elements respond to ground undulations or a control device and pivot or otherwise deflect. In one aspect, tines having supporting portions integral with outer bent end portions are spaced from adjacent tines a distance (between corresponding points) less than the combined length of the two aforementioned tine portions to ensure that crop is retained during rotation of the rake member. Alternate tines may have different lengths or the tines may have plates to facilitate crop retention. A wire or rope can be connected to the tines above their outer ends to enhance their crop working cooperation or the tines can be interconnected by tortional rod portions and/or loops that are integral for the same effect.

Abstract: A haymaking machine is provided with at least one rotary rake member having tines that are pivotable relative to a hub of that rake member about separate first and second axes to improve the tines ability to follow ground undulations during operation of the machine. The tines are adjustable in setting to suit different modes of operation of the machine, are pivotally supported by co-operating screw-threaded surfaces affording said first pivotal axes and are provided with adjustably positionable masses to vary the locations of the centers or points of gravity thereof.

Abstract: An apparatus for turning a compost silo has a portal frame adapted to travel along the ground in a travel direction and a pair of side portions spaced sufficiently apart transverse to the direction to straddle the silo. A pair of oppositely handed augers extending transverse to the travel direction between the side portions are rotatable to turn the silo. At each end this double auger is connected to the output of a respective angle drive having an input directed forwardly and connectable via a rod to the power takeoff of a tractor in front of and to one side of the frame relative to the travel direction. A tow bar has a rear end pivoted on the frame midway between the side portions and a front end connectable to the hitch of the tractor. Thus, this apparatus may follow the tractor to either side of the tractor.

Abstract: A raking implement has one or more rake heads each of which rotates about an upwardly extending shaft. Each rake head has tines that are movable into alternative crop working positions and the tines are pivoted on a support with connections to a ring-shaped adjustment member. The ring-shaped member is coaxial with the shaft and movable lengthwise of the shaft. The movements of the member lengthwise of the shaft or along the axis of rotation of the rake head causes the tines to pivot from one working position to another.

Abstract: A haying machine has a plurality of rotary rakes spaced apart transverse to its travel direction. Each rake has a plurality of tines extending through a housing rotatable about an upright axis and each having an inner end secured in a ball rotatable about an element nonrotatable in the housing but axially displaceable therein. The times each have an upper section about which they may be twisted by cam action, and a lower section that normally extends at a right angle to the ground. When the element in which the balls are carried is lifted all the way up control arms on the rake elements ride a cam to orient these elements with respect to the ground with the orbits of adjacent rakes spaced from each other, and when this bearing plate is lowered the control arms are moved out of contact with the cams in the housing and the rake elements are lifted so as to define an orbit of larger diameter that overlaps with the orbit of the neighboring rake.

Abstract: A haymaking machine has rake heads rotatable about upwardly extending axes. Each rake head includes a central housing mounted concentric with respect to a wheeled center shaft that affords the axis of rotation of the head. A p.t.o. is connectable to driving means that rotates the housing. Each head has support arms, the inner ends of which are pivoted on horizontal axes around the lower periphery of the housing. A tine group is pivoted to the outer end of each arm and the arm as well as its corresponding tine group are vertically movable about pivotal axes to a radial extended crop working position from a contracted and generally upright transport position. One or more spring mechanisms are associated with the pivotal axes to bias the arms and their tine groups to the transport position. Centrifugal forces overcome the spring bias when the head is rotated at operational speed.

Abstract: A rake device includes at least one rake member that rotates about an upwardly extending axis. The rake member has a hub and spokes that extend radially from the axis of rotation of the member. The outer circumference of the member is comprised of a circular wall made of flexible material. The outer wall is deformable in several directions to allow for ground deformations, and the lower part of the wall can have weights and/or pivotal connections to restrict the wall deformation. The spokes can be interconnected to the wall by flexible or resilient connections to allow for expansion due to centrifugal force when the rake member is rotated. Tines are connected to the wall, preferably around the lower skirt portion of the wall.

Abstract: A hay making machine has raking heads that rotate about non horizontal axes. Each head has a central hub with lower groups of tines pivotally connected to the hub around its lower periphery and vertically movable from generally radial crop working positions to an upwardly extending transport position. Upper crop working elements are also pivoted to the hub and independently turnable about horizontal axes. The upper elements can be further groups of tines or tubular crop engagers. In operation, the upper elements together with the lower elements present an inclined surface that engages long stemmed crop. By pivoting the lower groups, different angles of crop engaging surfaces are presented so that swath or tedding working positions are formed. The upper groups can be tines on further arms that pivot on support arms that connect the lower tine elements to the hub. The upper and lower groups are associated with pivots and stops to limit their working and transport positions.
