Abstract: An implement mounts a row of rotatable members, having resilient tines, that are rotatable about upwardly extending shafts. The frame portion is pivoted to a forward coupling member at several points, a lower one of which is a shear pin that allows the frame portion to tilt upwardly about an axis defined by two upper pivots upon overload of a tined member.

Abstract: A cultivating implement has an elongated frame portion that mounts a row of soil working members, each of which rotates about an upwardly extending shaft and mounts a lower tine or tines. The lower shaft end preferably is a flattened horizontal part and can have a threaded stub shaft that extends through a central hole in a matching horizontal tine fastening portion. Alternatively, the tine can be hollow and bolted to one side of a carrier. Preferably, the inner side of the tine is concave and a recess formed. Alternatively, the entire soil working portion is conical and tapers downwardly. The diameter of the upper part is at least five fold that of the lower part and is, at the most, one-fifth the total length of the soil working portion.

Abstract: A soil cultivating implement has tined, rotatable soil working implements mounted along the length of an elongated transverse frame portion that has carriers pivoted to the front of the frame by at least one pivot that defines a single axis. The rear ends of the carriers comprise stops with resilient connections that limit and bias the frame portion's position. The frame portion, together with soil working members are displaceable up and down relative to the remainder of the frame, responsive to ground conditions. Shield plates are mounted along the lengths of arms that pivotably interconnect a rear supporting roller to the front of the frame. Each working member includes a support made up of interconnected strips that are bent to form arms. The outer ends of the arms have plates and form holders that engage tine fastening portions. The strips are clamped between multi-sided plates and deflect when the tines encounter obstacles.

Abstract: A tank wagon for liquid material has interior partitions with dampeners to counteract movement and kenetic energy of the material with respect to the tank in one direction only. In this way, energy can be withdrawn from the liquid material movement during braking for instance, to mitigate adverse effects of such movement. In the embodiment detailed, partitions having openings are closed by hinged flaps during braking. Normally the flaps are gravity-urged to an open position. The tank can be composed of two compartments with different cross sections and length so that a lower and smaller compartment is located directly above a set of wheels. The larger compartment is contiguous with the upper part of the smaller compartment and is angled upwardly and forwardly. Thus, the lowermost portion of the larger compartment can be at the approximate level of the wheel axes.

Abstract: A drive transmission for a soil working implement includes spaced apart elongated tined beams that extend horizontally transverse to the direction of implement travel. The beams are driven to move vertically and horizontally through generally circular paths so that the tines are raised and lowered while moving laterally of the travel direction. A driving shaft and a driven shaft are spaced apart and extend perpendicular to the beams and above same. Each shaft mounts a respective eccentric disc that is fixed to each beam and an imput is connected to rotate the driving shaft which, in turn, rotates the driven shaft via the eccentric discs. The beams are connected to be displaced out-of-phase to mitigate vibration.

Abstract: An agricultural machine has at least one movable tool, such as a cultivating rotor, mower or raking member, spreader disc, or other driven member such as a tractor wheel or freely rotatable roller, which parts are interrupted in movement by a protective mechanism. The mechanism can be a pawl device associated with an overload coupling in the drive train that is actuated by a mechanical or electrical monitor to overload the device. The monitor can be a pivoted cover that partly overlies a rear roller or space adjacent same with projections that intercept the roller or a trip bar with contacts that opens or closes a circuit in a system that interrupts the drive to the moving parts responsive to contact with an external object. In another variation, the circuit can have sensors such as infrared or photoelectric cells to detect the presence or lack of presence of a human operator and these sensors can be placed in a tractor cab.

Abstract: A soil cultivating machine has a beamed frame, and working members arranged in pairs. Two working members are mounted one behind the other, preferably on a common carrier beam which is releasably secured to transverse beams of the frame. Thus the two working members and the carrier beam constitute a working unit which is readily releasable from the frame. The two working members of the pair are interlinked by a connecting rod to ensure a uniform operating depth over irregular ground and the members can be located on opposite sides of the carrier beam as viewed in plan. In one embodiment, the working members are mounted on pivot pins journalled to different frame beams and the members are arranged in rows that are inclined to the direction of travel. The beams with working members can be arranged in groups that are hinged to one another for elevation to a reduced transport position.

Abstract: A spreader suitable for spreading granular and/or powdery materials, such as seeds or fertilizer, comprises a distributor which has an upturned rim. The distributor can be driven in rotation or reciprocated about an axis which is inclined rearwardly from top to bottom at different speeds by means of a change-speed means. Frame members are orientated to prevent the least obstruction to material ejected past them by the distributor. A downwardly inclined deflector prevents material from impinging against a vehicle to which the spreader is hitched. The constructional features of the spreader contribute to an even distribution of material about the axis, regardless of the type of material being spread.

Abstract: A soil working machine comprises two interconnected soil working members. Each working member comprises a support that is preferably resilient and a lower working element. Deflection of one working member results in an opposite deflection of the other, but the orientation of the working elements is preferably maintained by a control arm. Levers pivoted to the frame and associated with the supports are interconnected by a rigid coupling. Alternatively, the supports can be attached to brackets which are pivoted to the frame and levers or parallelogram linkages interconnected to the brackets are connected by a rigid coupling.

Abstract: A mowing machine connectable by its frame to a three-point lift device of a tractor and powered by the power take-off of the tractor via belts and a gear train, to extend laterally relative to one side of the tractor. An outboard portion of the frame forms a housing for a gear train that rotates crop displacing members thereunder about shafts each having a gear supported at the lower end thereof which engages pinions on parallel offset shafts for mowing elements. Supporting members under each mowing element are offset to the rear to support the machine. A screening member extends above the mowing elements and to the rear where it is bent downwardly to be spaced a distance less than the height of the mowing element above the ground. Forward the screening member is crenated as seen from above so cutters pivotly mounted from each mowing element describe a cutting arc of about 60.degree. parallel to the adjacent arcuate portion of the screening member.

Abstract: A tractor has three pairs of ground wheels: a front steerable pair, a rear steerable pair and a central pair. The central pair of wheels each are fitted to the frame through a hydraulic piston assembly that can be controlled to raise those wheels above the ground or to lower the wheels to engage the ground. The central wheels can be the same as the other wheels or traction caged wheels of hollow beams wherein a hub is connected to outer fellies with spokes. Supports interconnect the fellies at the inner or outer sides. All of the wheels can be driven independently by an engine and the central wheels are each detachable from a driven axle. The hub of the central wheels includes an outer cylindrical sleeve to which an end plate and the spokes are affixed. Each wheel is mounted on a hydraulic motor which is mounted on the tractor's frame, the forward and rear motors being turnable with the wheels mounted thereon. A hydraulic jack connected to the motors of the central wheels is adapted to raise and lower same.

Abstract: An agricultural type tractor with lifting devices on the front, rear and both sides for agricultural implements. Each pair of rear drivable wheels which are in tandem pivot about a common axle and each pivotable pair of such wheels is driven by a separate hydraulic motor, with each motor, however, connected to a common control whereby the velocity of the wheels on one side can be increased while the velocity of those on the other is decreased for steering around curves and the like. The arrangement also provides a hydraulically lockable differential to avoid the spinning of one set of the drivable wheels while the other set does not move due to an obstruction or the like. Outboard of each set of drivable wheels is a rotatable supporting element which is mounted from the tractor's frame so as to be displaceable outwardly and upwardly relative to the adjacent 0010 set of drivable wheels. Each supporting element has two wheel members which receive an endless chain tread.

Abstract: A soil cultivating machine has a row of cultivating members which are mechanically driven and rotatable about upwardly extending axes positioned on a transverse row. An elongated, transverse hollow frame portion supports at least twenty shafts of the cultivating members and the shafts are preferably about 15 cms apart. Transmission parts of the members are housed in the frame portion. The frame portion comprises two U-shaped parts clamped together at longitudinal edges between which edges gasket material and spacer members hold the longitudinal edges at a predetermined distance from one another. The cultivating members can each have a single downwardly extending tine with an upper flat fastening portion that extends substantially transversely of the rotary axis of the cultivating member, and a lower operative portion that joins the flat fastening portion eccentrically of the rotary axis of the cultivating member.

Abstract: A soil cultivating implement has a frame portion of inverted channel-shaped cross-section with downwardly directed limbs each of which has an inwardly bent-over lip at its lower free end. A row of contra-rotating soil working members are carried by corresponding substantially vertical shafts. A power-operated drive transmission to the soil working members comprises the aforesaid vertical shafts, axially aligned, substantially horizontal shafts and intermeshing bevel pinions. In order to facilitate assembly as well as quick and simple replacement of any soil working member and/or transmission part that may become seriously worn, broken or damaged during operation, the transmission is made up of a plurality of successively neighboring gear casings any one of which can be individually removed, together with the corresponding soil working member and replaced by a similar unit.

Abstract: A soil cultivating machine has a frame and a rotor journalled in the frame, the rotor being an elongated rotatable carrier with a plurality of cultivating members mounted along the length of the rotor. To simplify manufacture, the rotor carrier has a plurality of projecting mountings that extend substantially parallel to the axis of rotation. Plate or sheet cultivating members are fastened to the mountings to extend substantially at right angles to the carrier. To ensure penetration into the soil, each cultivating member has a curved outer circumference and is of knife-formation. A portion of the member extends substantially parallel to the normal direction of rotation of the rotor and a further portion is bent-over at an angle to this direction. Viewed from the side, successive cultivating members at least partially overlap one another.

Abstract: A tractor which has three or four wheels on each side, two of the wheels on each side being mounted on a bogie which includes a wheel carrier. The bogie is pivotable relative to the rest of the vehicle about a horizontal transverse axle which connects it to the frame of the tractor. The foremost and rearmost wheels are steerable and driveable. In one embodiment, the intermediate wheels are also steerable and driveable. Lifting devices are provided to extend from both the forward and the rear of the tractor. An engine together with a transmission and differential gear is disposed between the foremost and the rearmost wheel axles. A cab has a driver's seat and steering wheel with a control console which may be rotated together whereby it selectively faces forwardly or to the rear. A cab in two embodiments is disposed forwardly and is centrally located in one embodiment.

Abstract: A cultivating implement has rows of tined soil working members that are freely rotatable about upwardly extending shafts. Each soil working member has tines positioned around the shaft which defines its axis of rotation. At the lower end of the shaft, a channelled feed member is attached and the shaft is hollow. Material from a container is dispensed from the container through the shaft and the feed member via a port to the ground being worked by the tines. The feed member is elongated and extends down, generally parallel to the tines of the corresponding soil working member which are mounted on circular plate supports. A further soil working member, preferably a supporting roller, is mounted behind the rows of soil working members.

Abstract: A tractor which is towing two agricultural implements extending transversely relative to the longitudinal axis of the tractor and having a width which is substantially greater than that of the tractor's width, the two implements being coupled to the tractor in tandem. The interior of the tractor's cab has a convex (as seen by the driver) mirror which extends almost completely across the interior of the glassed-in cab of the tractor so as not to block the driver's forward vision, whereby the driver can observe in the mirror both implements across their entire widths as well as the device for coupling both implements to the tractor. In a modification, the convex mirror is of less width (about one-half of the width of the cab) and is flanked by further mirrors on each side which reflect from still further mirrors mounted on the overhead of the cab to provide an increased lateral area which is within the vision of the driver through the mirrors.

Abstract: A hay machine for working crop lying on the ground, such as a side-delivery rake, a tedder or a combined hay-making machine has a tined carrier for redepositing worked crop on the ground and comprises rows of tines which, in operation, are rotated in a forward direction while being turned oppositely over at least part of their path near the ground. The tines, which are located near the ground, extend horizontally and in a forward direction with respect to the direction of machine movement. The carrier preferably mounts three rows of elongated tines that are each shaped as a lazy S and pointed at each end. A sun wheel and planet gear system drives the carrier as a whole while turning the tines to pick up crop, raise and deposit same to the rear of the carrier. The orientation of the tines can be adjusted by displacing the sun wheel relative to the frame and fixing same in position.
