Mower (1), having a plurality of mowing elements (2), which are positioned next to one another forming a mower bar (3), having a roller conditioner (4), which is arranged behind the mower bar (3), as seen in the material flow direction of mowed crop, and which has an upper conditioning roller (5) and a lower conditioning roller (6), wherein the lower conditioning roller (6) is rotatable about a lower, positionally fixed axis of rotation (8), wherein the upper conditioning roller (5) is rotatable about an upper, shiftable axis of rotation (9) in such a manner that, as a result of shifting the upper axis of rotation (9) relative to the lower axis of rotation (8), a gap (7) between the conditioning rollers (5, 6) is changeable, wherein the lower conditioning roller (6) and the upper conditioning roller (5) are coupled to each other via a scissors-like transmission (10), and wherein a first transmission part (11) is coupled to the lower conditioning roller (6) and a second transmission part (2) is coupled to the upper conditioning roller (5), wherein the transmission parts (11, 12) are operatively connected to each other and are shiftable in a scissors-like manner with respect to each other.

A mower conditioner implement includes a cutting system for cutting crop material, and a crop conditioning system for receiving the cut crop material from the cutting system and conditioning the cut crop material to facilitate drying. An image sensor senses an image of the cut crop material. The image includes a color spectrum of the cut crop material from reflected light emitted from a light source. A computing device compares the color spectrum of the image to a calibrated color measurement to determine an ash content in the cut crop material, and/or a degree of stem conditioning of the cut crop material. The computing device may then communicate the results to an operator, and/or adjust the cutting system or the crop conditioning system based on the ash content or the degree of stem conditioning.

A mower-conditioner (2, 6) for cutting and conditioning crop material, comprises a mower unit (2) for cutting crop material and a conditioner unit (6) that is configured to condition the cut crop material. A drive input (10) is configured to receive a rotational drive from an external drive unit, and a drive transmission system (30) is configured to transmit rotary drive from the drive input (10) to the mower unit (2) and the conditioner unit (6). The drive transmission system (30) includes a continuously variable transmission (CVT) (40) that transmits rotary drive between the mower unit (2) and the conditioner unit (6) with a variable speed ratio.

A sickle knife drive for an agricultural vehicle generally includes a first pump, a first motor, a second motor and a drive manifold having a plurality of connections used for connecting to other devices of the sickle knife drive and/or to devices outside of the sickle knife drive. Operation of the first pump in a forward direction causes the first motor to drive a sickle knife gearbox to cut a crop. During the forward direction, the second motor provides cooling to the fluid circuit. When the first pump direction is reversed, the agricultural vehicle supplements a fluid flow to the fluid circuit to clear any jammed crop from the sickle knives.

A forage harvester comprising a frame and a drive assembly is disclosed. The drive assembly comprises a drive pulley, a tension pulley, a plurality of additional pulleys and a drive belt for drivingly connecting the pulleys, a tensioning cylinder located between a first portion of the frame and a support element for the tension pulley. The frame is provided with a mounting at a second portion of the frame and the support element for the tension pulley is located between the mounting at a first end of the support element and the tensioning cylinder at a second end of the support element.

In one aspect, a system for supplying electric power to components of an agricultural harvester may include a power storage device and a first agricultural harvester component. The system may also include a first bus electrically coupled to the power storage device and configured to supply electric power at a first voltage to the first agricultural harvester component. Furthermore, the system may include a second agricultural harvester component and a second bus configured to supply the electric power at a second voltage to second agricultural harvester component, the second voltage being less than the first voltage. Additionally, the system may include a converter electrically coupled between the first and the second bus, with the converter configured to reduce the first voltage supplied through the first bus to allow electric power to be supplied to the second agricultural harvester component at the second voltage via the second bus.

Mower (1), has a plurality of mowing elements (2), forming a mower bar (3), a roller conditioner (4), behind the mower bar (3), and an upper conditioning roller (5) and a lower conditioning roller (6), the lower conditioning roller (6) is rotatable about a lower, positionally fixed axis of rotation (8), wherein the upper conditioning roller (5) is rotatable about an upper, shiftable axis of rotation (9) that, as a result of shifting the upper axis of rotation (9), a gap (7) between the conditioning rollers (5, 6) is changeable, wherein the lower conditioning roller (6) and the upper conditioning roller (5) are coupled to each other via a scissors-like transmission (10), and wherein first and second transmission parts (11,12) are coupled to the lower conditioning roller (6) and the upper conditioning roller (5) respectively and are operatively connected to each other and are shiftable in a scissors-like manner.

A mower-conditioner assembly of a self-propelled windrower includes a frame, a cutting mechanism coupled to the frame for cutting crop, a conditioner rotatably coupled to the frame at a location rearward of the cutting mechanism, and a fluffer assembly rotatably coupled to the frame at a location rearward of the conditioner. The fluffer assembly includes at least an elongated roll and a crop moving element. The conditioner crimps the crop after it is cut, and the fluffer assembly fluffs or moves the crop during operation.

In a forage harvester cracker unit drive assembly for driving a first cracker roller and a second cracker roller, the drive assembly comprising a drive pulley, a tension pulley, a first cracker pulley associated with the first cracker roller, a second cracker pulley associated with the second cracker roller, a guide pulley, and a drive belt drivingly connecting each of these pulleys, the drive assembly further comprises a guide pulley adjustment apparatus for adjusting the position of the guide pulley with respect to the second cracker pulley.
