Abstract: A rotary harrow or cultivator tine has an upper fastening portion that is tightly received in a holder. The fastening portion is integral with a lower soil working portion that terminates in a tip and the two portions are angled with respect to one another. The soil working portion has a generally round cross section for a part of its length that is tapered outwardly to form a leading rib with respect to the intended direction of rotation of the tine. In the lower region adjacent the tip, the cross section of the soil working portion becomes less round and can merge into a polygonal cross section region having grooves and flat sides.

Abstract: A raking machine has preferably two rake heads that are rotatable about upwardly extending axes. Each rake head has an outer circumference defined by a generally circular flexible wall with raking means supported on the circumference of the wall. The wall can have stiffening members to reinforce the wall and to hold tines or tine groups that can be pivotally mounted adjacent the lower portion of the wall. Also, the wall can be supported from a central hub by flexible spokes or chains. Alternatively, the wall can be foldable to an accordian configuration and hold crop within the folds which are controlled by a link chain and track with a driven sprocket member. The flexible wall is controlled to deposit crop at the desired place during rotation of the head or heads and crop guide members can be positioned with respect to the head or heads to arrange the crop in swaths.

Abstract: A spreading implement has at least one hopper, preferably with two outlet spouts at the bottom thereof. Each spout has an outlet port through which material passes and a flow control device having holes is positioned beneath each port. A group of distributor pipes is mounted below a corresponding control device at each side of the hopper and the pipes extend laterally from the implement to terminate with outlets at different distances from the hopper. The inner ends of each group of pipes adjoin an inlet nozzle formed by open pipe channels and connectors that correspond to each pipe. The channels receive material from corresponding holes in the control device and the latter can be moved via a setting device to more or less register with apertures formed in a cover plate that overlies said channels. An enclosed air chamber is formed between the spouts at the bottom of the hopper and a blower forces air through the chamber into each inlet nozzle that enters the sides of the chamber.

Abstract: A soil engaging roller has a central axis shaft and spaced apart plate-like supports secured to the shaft. The supports are upwardly extending with holes around their perimeters to receive elongated rod-type elements that form the periphery of the roller. The elements can have retaining devices in the form of transverse holes with pins that secure the elements in the holes of the supports. The rods are shiftable or reversible with respect to the supports so that as the contacting surfaces become worn the elements can be altered to occupy different longitudinal positions. The support holes can be punched out with bearing surfaces formed by the bent over rim. Also, the supports can be angled with respect to the shaft and the elements can have several transverse retaining holes to permit shifting and retaining of the elements to the supports.

Abstract: A cultivator has soil working blade members mounted on a horizontal shaft which is driven to rotate the members forwardly through the soil in the normal direction of travel. A baffle comprised of screen segments are mounted on the cultivator frame to partially surround the blade members. The screen segments are biased about respective pivots and a rod grating is connected to the baffle to extend downardly immediately to the rear of the blade members. The rear screen segment has V-shaped guides to ridge the soil. A hopper communicates with dosing outlets, each outlet being a nozzle device that extends between a pair of guides. Each nozzle device is pivotable to either one of two positions for planting tubers deep or shallow. A pair of rear wheels is connected to the rear of the frame and the wheels are drivenly connected to dosing conveyors leading to the outlets. An adjusting device is associated with each wheel to raise and lower the soil working blade members.

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: A cultivator implement has at least one frame portion that houses a row of soil working members connected to driving means which rotates those members about corresponding upwardly extending axes. A supporting frame is designed to overlie and support the soil working members during operation and/or transport of the implement. The supporting frame comprises a plurality of substantially parallel beams that extend transverse to the normal direction of operative travel. The beams are spaced apart and positioned at different levels above the ground and interconnected with plates for strength and to properly support the implement. The beams are of angular, preferably square, cross section so that a diagonal of a beam extends substantially vertical for further strength. A coupling member is interconnected to the beams with struts so that the implement can be attached to a prime mover for operation.

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 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 harrow has rotary soil-working members in driving connection and spaced apart from one another to work non overlapping paths through the soil being cultivated. Between the rotary soil-working members, non rotary tines are positioned to work the strips remaining between the paths already worked. The non rotary tines are pivoted to the frame to move to and fro through the strips during travel. The rotary soil-working members are tined supports and the supports are elongated horizontal members to which arcuate-shaped brackets are attached. The brackets afford stops for the non rotary tines that are moving to and fro during operation so that the to and fro movements of the non rotary tines are limited.

Abstract: A steel soil cultivating tine has a lower soil working portion and an upper fastening portion. The tine has zones of differing hardness along its length, the hardest zone including the lowermost end of the tine. The tine can take different shapes and configurations, but in general the soil working portion has sides, at least several of which taper towards the lowermost end. The fastening portion can be threaded for reception in a threaded holder. Near the juncture between the fastening and soil working portions a zone of reduced hardness lends flexibility to the tine.

Abstract: A crop drier has an enclosed drying chamber with an entrance at the front thereof and an exit adjacent the back thereof. A conveyor system includes a floor conveyor for receiving long stemmed crop and conveying it to a lifting conveyor which drops the crop on a lower transverse conveyor at the rear of the chamber. The lifting conveyor is configured as a right angled triangle that lifts and drops crop on an elevator conveyor at one side of the chamber. The latter conveyor then moves the crop to an upper transverse conveyor at the top of the chamber near the front thereof.The upper conveyor is structured to reciprocate within the chamber across its width while continuously receiving crop from the elevator conveyor.
