The present invention relates to the general technical field of agricultural machinery. It concerns an agricultural device, in particular a haymaking device, which can be moved in a direction of advance and which includes a cutter bar equipped with cutting elements intended to cut a standing crop product. The device also comprises a conditioner positioned behind the bar, and a grouping device intended to move the product transversely to the direction of advance and located behind the bar, in an active position. A retraction actuator is configured to transpose the grouping device between the active position and a passive position in which the product is deposited at the rear of the device. A collecting device extends partially under and partially behind the conditioner in active position of the grouping device. The invention also concerns an agricultural machine equipped with such a device and a method for access between a conditioner and a grouping device belonging to such a device.

A drive system for self-propelling harvester is disclosed. The harvester includes a drive motor, a transfer case driven by the drive motor and having an output pulley arranged on a driveshaft of the transfer case and driving, using a main drive belt, at least one main pulley of a rotating cutter drum arranged on the end of a cutter drum shaft, a conditioning apparatus, an ejection accelerator, and a hydraulic pump for hydraulically driving an attachment and/or a feed device. The output pulley, the main drive belt and the main pulley form a main drivetrain for driving the cutter drum, the conditioning apparatus, and the ejection accelerator, and the attachment and the feed device are each driven by a separate drivetrain. At least one prop shaft, on the side of the main drivetrain, is arranged or positioned to lie in a common vertical plane with the main drive belt.

A crop conditioning device for an agricultural harvesting machine. The crop conditioning device includes a frame, a first conditioning roll, and a second conditioning roll. The crop conditioning device also includes a tension member operably connected to the second conditioning roll. The tension member is configured for applying a tension force on the second conditioning roll. The crop conditioning device also includes a tension actuator operably connected to the tension member. The tension actuator is configured for adjusting the tension force applied by the tension member. The crop conditioning device also includes a pair of control rods respectively connected to the pair of lateral ends of the second conditioning roll. The crop conditioning device also includes a pair of roll-gap actuators respectively and operably connected to the pair of control rods. The pair of roll-gap actuators are configured for pivoting the second conditioning roll to adjust the roll gap.

A conditioning roller assembly includes two conditioning rollers which are rotatably mounted on associated bearing arrangements, and a holder which includes a first holder component and a second holder component that are connected together by a hinge and a spring arrangement for providing a pre-tensioning of the conditioning rollers. The first holder component is releasably connected to the first bearing arrangement, the second holder component is releasably connected to the second bearing arrangement, and the conditioning rollers, with the bearing arrangements, are detachable in each case from the components without the holder being disassembled.

A conditioner assembly in an agricultural implement for conditioning cut crop material includes a top roll and a bottom roll rotatably supported by a pair of lateral side walls. The top roll is arranged relative to the bottom roll to define a roll gap therebetween for conditioning the cut crop material as the cut crop material passes therethrough. A stabilizing link extends between each of the lateral side walls and the top roll for pivotally coupling the top roll to the conditioner frame, and an adjustment mechanism extends between each of the lateral side walls and the top roll. The adjustment mechanism is selectively and remotely actuatable to automatically pivot the top roll toward and away from the bottom roll, thereby decreasing and increasing the roll gap for optimally conditioning different types and volumes of cut crop material received by the agricultural implement.
