Openers for a seeder, configured to be adjustably engaged with a soil surface when in use; each opener having compliance to vertical and lateral excessive forces independently applied to soil-engaging parts: a fertiliser tine, a seed tine, a press wheel, a coulter, and a support wheel. The openers share a hydraulic circuit, linked to each internal frame-lifting ram so that localised rise and fall effects arising from soil surface irregularities are shared, maintaining a mean height. The seed tine of each opener is mechanically coupled to the preceding fertilizer tine and is lifted when the fertilizer tine is displaced. The openers do not require external weight support.

A sowing coulter arrangement comprises a suspension device for mounting the sowing coulter arrangement on a machine frame; a coulter frame connected to the suspension device for mounting components of the sowing coulter arrangement thereon; and a coulter disk. The arrangement further comprises a furrow closer pivotally mounted on the coulter frame; a metering device for dispensing the material to be distributed; a seed tube for transporting the material to be distributed from the metering device to a seed furrow; and a catching element for catching the material disposed downstream of the outlet of the seed tube. The metering device, the seed tube, and the catching element form a unit and are mounted on a carrier that is pivotably affixed to the coulter frame, whereby an arrangement of an outlet of a seed tube in relation to a catching element is at all times kept largely constant.

The invention relates to a soil-working device having an overload protection means, in the case of which overload protection means rebound energy is reduced after the soil-working device returns from an overload position to the working position.

In order to require as few load measuring units (50) as possible and yet always know the loads acting on the boom (3, 4) independently of the working head (2) currently attached to the boom (3, 4), the load measuring unit (50), in particular only one, is either on or in the boom (3, 4), in particular fixed, or between arm end (18a) of the boom and the head end (18b) of the working head (2) facing it.

An agricultural device associated with reduced tillage techniques in a field includes a frame and a separator supported by the frame. The separator is configured to form a strip of exposed soil in residual plant matter in the field. A crimping device associated with the separator is configured to at least partially crush sterns of residual plant matter while maintaining the strip.

In one aspect, a finishing assembly for an agricultural implement may include first and second rolling baskets, a basket support assembly configured to support the first and second rolling baskets relative to each other, a linkage pivotably coupled to the basket support assembly at a pivot point, and at least one damping element. The at least one damping element may be configured to damp pivoting of the basket support assembly about the pivot point in both a first pivot direction and a second pivot direction, the second pivot direction being opposite the first pivot direction.

In the case of a soil cultivation device with multiple harrow tines, the harrow tines are fastened to levers, which are mounted to pivot on tie bars of the supporting frame via carriers. The operating position of the harrow tines is defined by the levers being adjacent to tie bars, and the harrow tines are prestressed into the operating position by springs assigned to them in the form of pneumatic cylinders.

A harrow has a frame, tines pivotal on the frame and each a lower arm with a soil surface under the harrow. An actuator on the frame can shift a bar frame shiftable horizontally on the frame. Respective spring biasing units above the axes each have a guide element connected to the bar frame and displaceable therewith through a predetermined displacement path, a connecting element connected to respective upper arms of the tines, a first compression spring bearing on both of the elements and biasing the other element away from the one element so as to press the lower arm downward into the soil surface during movement of the respective guide element through the path, and a second compression spring bearing continuously on one of the elements and engageable with the other of the elements after displacement of the respective spring-biasing unit only through a part of the path.
