A grass management system includes a first moisture-obtaining device to obtain a first moisture value of grass in a mowing operation performed by a mower, a position-detecting device to detect a mowing position of the mower, and a creation supporting circuit to support creation of an operation plan for a working machine based on the first moisture value and the mowing position, the working machine being configured to perform an operation relating to the grass already mowed. The grass management system includes a moisture map creating circuit to create a moisture map of an agricultural field based on the first moisture value and the mowing position. The creation supporting circuit is configured to display the moisture map that is created by the moisture map creating circuit in creating the operation plan.

A defoliator having a frame suitable for mounting to a vehicle supports an elongated main support arm which extends substantially horizontally, and which has a tine-bearing main shaft which rotates to have the tines knock at least some leaves (or portions thereof) from plants beneath. The main support arm rides on wheels, and may pivot and vertically translate with respect to the frame such that the main support arm (and the tined main shaft) will generally follow the elevation and contour of the ground beneath. To defoliate greater areas, one or both ends of the main shaft may be connected to a boom arm hearing a rotating tined arm shaft, which extends the effective length of the main support arm and tined main shaft. The boom arms are preferably capable of folding rearwardly to reduce the effective size of the defoliator for easier transport.

Harvesting apparatus, with a supporting frame (12) having a longitudinal member and crossmembers, with a chassis (18) having wheels (19), with pickup members (20) which are designed as a pickup and transverse conveyor devices (21) designed as belt conveyors, wherein a respective pickup member and a respective transverse conveyor device are arranged on a first and second side of the longitudinal member (13), wherein a first shiftable crossmember (14) which is arranged on the respective side of the longitudinal member and accommodates the respective pickup member (20) and the respective transverse conveyor device (21) is shiftable about an axis (24) extending in a height direction relative to a second shiftable crossmember (15) and is furthermore shiftable via the second crossmember about an axis (25) extending in the longitudinal direction relative to a fixed crossmember (16), and wherein a respective first overload protection device (26) is positioned between the first and second shiftable crossmembers (14, 15) arranged on the respective side of the longitudinal member (13), said overload protection device triggering when a force which acts on the respective pickup member (20) and/or the respective transverse conveyor device (21) and/or the respective first crossmember (14) in counter to the harvesting direction exceeds a limit value and permitting shifting of the respective pickup member (20) and of the respective transverse conveyor device (21) rearwards about the axis (24) extending in a height direction.

Transverse conveyor (12) of an agricultural harvesting machine, in order to convey harvested crop in a conveying direction running transversely with respect to the direction of movement of the harvesting machine, with a transverse conveyor belt (14), and with lateral deflecting pulleys (15, 16) on which the transverse conveyor belt (14) is guided, wherein each of the lateral deflecting pulleys (15, 16) is assigned a respective drive unit (17, 18), with the aid of which the transverse conveyor belt (14) is drivable.

Harvesting apparatus, namely merger or pickup head, with a loadbearing frame (11) which has a longitudinal carrier (12) and crossmembers (13, 14, 24, 25), with a chassis (16) which has wheels (17), with receiving members (18) which are configured as a pickup for receiving harvested crops, one receiving member (18) on a first side of the longitudinal carrier (12) and a further receiving member (18) on a second side of the longitudinal carrier (12) being received in each case on a crossmember (13, 14), and with cross conveying devices (19) which are configured as belt conveyors for conveying the received harvested crops in a cross conveying direction which runs transversely with respect to a longitudinal direction, one cross conveying device (19) on a first side of the longitudinal carrier (12) and a further cross conveying device (19) on a second side of the longitudinal carrier (12) being received on the respective crossmember (13, 14), and it being possible for a transfer region (22) for the harvested crops to be configured between the cross conveying devices (19) which are arranged on different sides of the loadbearing frame (12). In the working position, the cross conveying devices (19) and receiving members (18) which are arranged on the different sides of the loadbearing frame (12) can be pivoted about in each case one pivot axis (28, 29) which extends in the longitudinal direction, the respective pivot axis (28, 29) being arranged in the region of the chassis (16) adjacently with respect to the transfer region (22).

An agricultural machine includes a frame, and a lifting unit configured to vary a height of an operating unit with respect to a supporting surface for the machine. The lifting unit includes hydraulic cylinder with a liner and first and second pistons both slidingly housed inside the liner and arranged in series to define first and second chambers inside the liner, wherein the first and second pistons are controllable independently. The lifting unit includes a pressure stabilizer in fluid connection with the first chamber and that controls a pressure in the first chamber so that the first piston moves therein as a force generated on the first piston varies. A second control element for the second chamber carries out a volumetric control of the second chamber to control a position of the second piston regardless of a pressure inside the second chamber.

A self-propelled agricultural machine, for example, a self-propelled merger, is provided with at least one motor, at least two elongate units for, in use, performing an agricultural operation on the land, a front wheel axle, and a rear wheel axle situated at a distance from the front wheel axle. The front wheel axle and/or the rear wheel axle is driven by the motor for displacing the agricultural machine. Each elongate unit is displaceable from a transportation position to a working position and vice versa by a folding mechanism, so that the maximum width of the self-propelled agricultural machine is smaller in the transportation position of the units than in the working position of the units. In the working position, the agricultural operation on the land is performed substantially along the length of each elongate unit.
