Disclosed herein is a vehicle (1)—preferably a tractor—with a trailer (2) operatively connected thereto with a cardan (3), said cardan (3) comprising a power take-off, said power take-off being switched off when said cardan (3) builds with said vehicle (1) and/or with said trailer (2) an angle (ϵ) smaller than a first threshold value (a) and/or larger than a second threshold value (β) and being switched on when said angle (ϵ) exceeds again said first threshold value (β) thanks to suitable actuators, including detection means of the angle formed between the cardan (3) and said vehicle and/or trailer. According to the present invention, said angle (ϵ) is detected by a detector consisting of a magnetic device (4) placed on the trailer (2) or the vehicle (1) and an electronic compass (5) placed on the vehicle (1) or on the trailer (2). Preferably, the angle (ϵ) insisting on the cardan (3) is obtained according to the formula: ϵ=180−Y−arcsen (l/m sen y) (3) where y is the angle the compass (5) forms with respect to the straight travel with the magnet (4), I is the distance between the cardan (3) and the compass (5), m is the distance between the cardan (3) and the magnet (4).

An offset arm for a tractor is provided. The offset arm includes a front hitch, a rear hitch, and a rigid connecting structure coupling the front hitch to the rear hitch. The offset arm also includes a front pivot point pivotally connecting the connecting structure to the front hitch about a vertical pivot axis and a rear pivot point pivotally connecting the connecting structure to the rear hitch about a vertical pivot axis. The offset arm also includes a rear pivot lock that selectively locks the rear pivot point to lock the orientation of the rear hitch relative to the connecting structure. The rear pivot lock can selectively lock the rear hitch in any of multiple orientations.

An articulated towing apparatus pulls a rotary driven implement in a forward working direction across a ground surface behind a towing vehicle. The apparatus includes a longitudinal frame pivotally connected at a leading end to the towing vehicle by a coupling frame and pivotally connected at a trailing end to a wheeled frame that supports the implement thereon. The coupling frame defines lateral and vertical pivot axes between the longitudinal frame and the towing vehicle. A drive line, connected between a power take-off of the towing vehicle and the implement, includes (i) a longitudinal drive shaft extending at a downward slope, and (ii) an output for connection to the implement that is rotatably supported on the wheeled frame.

A hitch configured to selectively latch to a tow bar is provided. The hitch includes a housing, a frame defining a receiving cavity, a moveable arm, an actuator configured to move the arm between an unlatched position and a latched position, and a contact sensor mounted within the housing on a slotted mounting plate. The arm is configured to engage the tow bar when in the latched position. The slotted mounting plate is configured to enable a position of the contact sensor to be adjusted based on a geometry of the tow bar. The actuator is activated by the contact sensor sensing the presence of the tow bar within the receiving cavity.

A steerable axle includes a housing defining a ball seat therein, a ball member received within the ball seat and defining a cutout portion to receive a portion of a ball bearing therein, an interstitial space defined by a surface of the ball seat and a surface of the ball member, and a ball bearing disposed within the interstitial space and received into the cutout portion of the ball member. The ball bearing moves within the interstitial space when the ball member rotates along the x or y axis, but is restricted from movement along the z axis. Restriction of movement of the ball bearing along the z axis results in a corresponding restriction of movement of the ball member along the z axis.

The present invention relates to a bale pick-up device for picking up of at least one round bale from a round baler, comprising a coupling device with at least one coupling frame element to be fixedly arranged on a machine frame of the round baler and at least one drawbar element extending in a pick-up direction at least partially between the coupling frame element and a machine frame of the bale pick-up device and mounted in such a way on the coupling device that it is pivotably movable relative to the coupling frame element at least about a vertical axis perpendicular to a contact surface of the bale pick-up device at least in a first position of the coupling device, wherein a guide element mounted on the coupling device and pivotably movable relative to the drawbar element at least about the vertical axis and extending in the pick-up direction in such a way that the drawbar element is arranged at least partially between the transfer element and the contact surface in a side view. The present invention moreover relates to a vehicle combination with a round baler and such a bale pick-up device.

A tool bar and hydraulic system for a large scale agricultural implement. The tool bar includes opposed pivotable wings that are extended in a field configuration and retracted in a transport configuration. In some embodiments, each pivotable wing includes two lift assist assemblies for aiding in the execution of turns in the field, and for aiding in the transport of the agricultural implement. The tool bar may be configured to compensate for twist of the pivotable wings when in the transport configuration. The hydraulic system is configured to stiffen the tool bar assembly for lift assist during field operation and to flex the tool bar into a folded configuration for transport.
