Disclosed is a connection device for an agricultural machine, the device including: a front having an input shaft coupled with an input yoke and installed passing therethrough; a rear body having an output shaft coupled with an output yoke and installed passing therethrough; a joint part provided to allow each of the bodies to be coupled with each other and to be rotatable via center pins installed on central parts of upper and lower tip ends of each of the bodies; and a connection yoke fastening each of the input and output yokes thereto via “+” shaped bearings, wherein in the “+” shaped bearings, a length “L” of the connection yoke fastening shafts fastened to the connection yoke is formed to be longer than the length “l” of the input and output connection yoke fastening shafts fastened to the input and output yokes.

Disclosed herein is vehicle (1) with 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) forms with said vehicle (1) and/or with said trailer (2) an angle (α; β) smaller than a first threshold value and/or larger than a second threshold value and being switched on when said angle exceeds again said first threshold value or goes below said other threshold value, due to suitable actuators. According to the invention, it provides angle (δ) detection means between the steering wheels (5) and the axle (A) of the vehicle and means apt to correlate said angle (δ) between the steering wheels (5) and the axle (A) of the vehicle (1) with the angle (α; β) comprised between the cardan (3) and said vehicle (1) and/or said trailer (2).

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.

Agricultural implement having a tow bar device for towing the implement with a towing vehicle includes an implement part that trails the tow bar device mounted so as to be pivotable about a first pivot axis. The first pivot axis is parallel to a horizontal transverse axis of the implement. The trailing implement part and the tow bar device are coupled by means of at least one first actuator. The tow bar device, by means of the first actuator, is pivotable about the first pivot axis in such a manner that a tilt angle between the tow bar device and the trailing implement part is adjustable.

An agricultural implement includes: a center frame defining a travel axis; a tool bar connected to the center frame and extending transversely to the travel axis; a first row unit having a first parallel linkage defining a first linkage angle relative to the tool bar; a first angle sensor associated with the tool bar and the first parallel linkage and configured to output a first linkage angle signal corresponding to the first linkage angle; an actuator linked to the first row unit and configured to adjust the first linkage angle; and a controller operationally coupled to the first angle sensor and the actuator. The controller is configured to: determine the first linkage angle; compare the first linkage angle to a preset linkage angle; and activate the actuator to adjust the first linkage angle to the preset linkage angle if the first linkage angle deviates from the preset linkage angle.

A universal joint shaft can be provided for transmitting torque between a power take-off shaft of a driving agricultural machine and a drive journal of an agricultural implement to be driven. The universal joint shaft comprises

a first joint with a first inner joint member and a first outer joint member, which are pivotably and torque-transmittingly connected to each other, a second joint, with a second inner joint member and a second outer joint member, which are pivotably and torque-transmittingly connected to each other, a connecting shaft, via which the first inner joint member and the second inner joint member are connected to each other in a rotationally fixed manner, and
a connecting hub which is rigidly connected to the first outer joint member and has connecting means for connecting the connecting hub to a shaft in a rotationally fixed manner, a housing in which the connecting hub is accommodated and rotatably mounted, and a generator accommodated in the housing, said generator has a stator rigidly connected to the housing and arranged coaxially to the connecting hub, and said generator further has a rotor rotatably mounted relative to the housing, wherein the rotor is drivingly connected to the connecting hub via a transmission.

A work vehicle includes: a chassis; a housing carried by the chassis and including a cowl; a power take-off extending through the cowl and configured to connect to a power source; and an attachment movably coupled to the housing and including: at least one driven element coupled to the power take-off; and a shield assembly associated with and covering the power take-off. The shield assembly includes a rigid section defining a first diameter and a flexible section coupled to the rigid section and defining a second diameter that is greater than the first diameter. The flexible section is configured to fit over and maintain overlap with the cowl during tilting of the attachment.

A flex wing cutter is equipped with a splitter gearbox and a plurality of drivelines. Each driveline is coupled to the splitter gearbox via a clutch assembly, and supplies power to a drive gearbox and cutting blade assembly on a wing of the flex wing cutter. Each clutch assembly is equipped to an actuator, the actuator configured to selectively engage or disengage the driveline from receiving rotational power from the splitter gearbox. Each actuator can be remotely controlled from a control located in a cab of a towing vehicle, such as a tractor, allowing an operator of the flex wing cutter to remotely deactivate the cutting blade assemblies of either or both wings of a flex wing cutter.
