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.

A forage harvester cracker unit assembly for retention of first and second cracker rollers, each of the first and second cracker rollers having first and second ends and sealing units fitted at each of the first and second ends. The forage harvester cracker unit assembly comprises an upper housing having left and right hand sides, and a lower housing having left and right hand sides. The forage harvester cracker unit assembly further comprises first and second sets of replaceable cracker roller sealing unit location plates, each set comprising an upper cracker roller sealing unit location plate and a lower cracker roller sealing unit location plate for location at a respective left or right hand side of a respective upper or lower housing.

An agricultural crop conditioner comprising: a frame; first and second conditioner rolls with the second conditioner roll being movable towards and away from the first conditioner roll to change a size of a gap between the rolls; a tensioner configured to generate closing force component to bias the second conditioner roll in the closing direction; a conditioner roll drive circuit; and a hydraulic actuator. The conditioner roll drive circuit has a hydraulic pump and motor to drive at least one of the conditioner rolls. The hydraulic actuator is configured to convert pressure from hydraulic fluid in the reverse supply line into an opening force to bias the second conditioner roll away from the first conditioner roll. The opening force is less than the closing force when the pump is operated in a forward direction, and greater than the closing force when the pump is operated in a reverse direction.

One or more techniques and/or systems are disclosed for developing appropriate settings for a windrower implement or forage harvester implement, to obtain a desired crop conditioning profile for a target crop. Field crop conditions may vary due to soil conditions, moisture content, and the operator may wish to get crop uniformity when collected. As such, a profile can be developed that provides adjustment data to actuators to adjust machine setting, to provide for a conditioning systems to obtain a desired result. The adjustment data can be generated based on such as the moisture content of the target crop, the target moisture content, and the dry-down characteristics for the crop. The profile can help set the harvesting system to provide appropriate cut and crimp to result in a desired dry-down time to get uniformity in the collected crop.
