An apparatus for combining planting implements enables an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. The apparatus is rigidly affixed to a conventional cultivating implement and comprises a support frame, a pair of brackets, and a connection bar. In combination, the support frame, pair of brackets, and connection bar provide a three-point connection whereby a conventional broadcasting implement may be attached thereto, thus enabling an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. In operation, at least a portion of the conventional cultivating implement is disposed behind the conventional broadcasting implement when the conventional broadcasting implement is attached to the support frame, thereby allowing simultaneous cultivation and broadcasting of constituents.

A work vehicle multi-coupler assembly having a controlled breakaway feature include a pair of coupling elements that mate along a coupling axis. A shear pin is carried by one of the coupling elements. A coupler mechanism connected to the second coupling element and configured to engage the shear pin to bring the first coupling element into mating engagement with the second coupling element. The coupler mechanism is configured to shear the shear pin to permit movement of the first coupling element away from the second coupling element along the coupling axis during a breakaway event.

A shock-absorbing tongue assembly for coupling a rotary cutter with a work vehicle includes a coupler configured to couple to the work vehicle, and a linkage mechanism having a proximal end at the rotary cutter and a distal end at the coupler. The linkage mechanism includes a suspension element configured to dampen energy transferred between the rotary cutter and the work vehicle, a primary linkage mechanism extending from the rotary cutter, and a secondary linkage mechanism extending between the primary linkage mechanism and the coupler. The secondary linkage mechanism is configured to rotate about the primary linkage mechanism while maintaining the coupler in a level condition.

An auxiliary track device for movement of a vehicle. The auxiliary track device may enhance traction and/or floatation of the vehicle, such as, for example, by being installable on the vehicle to convert the vehicle into a tracked one and/or by being deployable to engage the ground in certain situations, including where additional traction and/or floatation may be desirable based on an environment of the vehicle such as one or more characteristics of the ground (e.g., a compliance, such as a softness or hardness, a slipperiness, a soil compatibility, and/or a profile of the ground), a state of the vehicle (e.g., a speed of the vehicle, loading carried by the vehicle, etc.), a user's preferences (e.g., ride quality, etc.), and/or any other suitable factor. The auxiliary track device may be used only for traction and/or floatation of the vehicle or may be part of an implement to perform work with the vehicle.

The invention relates to an arrangement for attaching a working tool to a working machine, preferably to a three-point hitch of the working machine, comprising a pushing arm articulated, at one end, to the working machine, and two pulling arms articulated, at one end, to the working machine. The arrangement comprises a coupling mechanism for attaching the three-point hitch, from the cabin of the working machine, to the working tool, or, to a quick hitch positioned between the working tool and the working machine.

A lift link assembly of a three-point hitch. The lift link assembly includes a yoke, a shaft, and a retractor. The yoke includes a main housing and first and second side arms that extend downwardly therefrom. The shaft includes a shank and a head positioned on a lower-end thereof, and the shank is positioned in the upper-end through hole. When the lift link assembly is in a retracted mode, the retractor is positioned above the head, the retractor is configured to apply a downward force to the head, and the retractor is configured to apply an upward force to the yoke.

Coupling apparatus for coupling a mower to a front three-point linkage of a tractor includes a mounting element for coupling to the three-point linkage and a carrier element to which the mower is coupled. A linkage mechanism including upper link members and a lower link member couples the carrier element to the mounting element. The lower link member is pivotally coupled to the mounting element about a first lower pivot axis. A pair of take-up springs act between the lower link member and the mounting element to take up a portion of the weight of the mower. The take-up springs are coupled between corresponding anchor elements and corresponding anchor brackets on the lower link member. The anchor elements are carried on respective compensating arms, which in turn are pivotal on pivot shafts carried on the mounting element. Actuator arms acting between the lower link member and the compensating arms urge the anchor element upwardly and downwardly as the carrier element moves upwardly and downwardly for controlling the turning moment induced by the take-up springs in the linkage mechanism, in order to maintain the effective weight of the mower bearing on the ground substantially constant.
