A windrower has a hydrostatic header drive system with a header drive pump and one or more header drive motors. The windrower also has a chassis with wheels coupled thereto, an engine, and a ground drive system coupled to the wheels and the engine. A control system has plural sensors having first, second, and third sensors, wherein the first sensor monitors engine load, the second sensor monitors hydrostatic header drive pressure, and the third sensor monitors ground speed. The control system has one or more controllers configured to receive input from the plural sensors, compare the input with respective target values for engine load, header drive pressure, and ground speed throughout a range of ground speeds defined based on an operator configured maximum ground speed, and automatically adjust the ground speed based on the comparison.

A crop harvesting header includes a reel rotatable about a reel axis. The reel has a reel bat supported at a spaced distance from the reel axis. The reel bat can pivot about a bat axis radially spaced from the reel axis. The reel bat has a crop collection member that extends generally away from the bat axis. The reel bat can move in a cyclical path around the reel axis during rotation of the reel. The reel bat can vary the angle of the crop collection member about the bat axis as the reel rotates about the reel axis. A sun gear is provided that may be positioned in axial alignment with the reel axis. A planetary gear system is rotatable about the sun gear. The planetary gear system interacts with the sun gear, and causes said planetary gear system to effect pivotal movement of the reel bat about its bat axis.

A cam track adjustment mechanism for use with the pick-up reel of a harvester. A cam track is provided which is rotatably adjustable about an axis which is spaced away from the fixed axis of rotation of the pick-up reel. The two axes may be generally horizontally aligned relative to each other. Preferably, the cam track is rotatable around a point away from the fixed reel axis and generally on the horizontal plane of the rotational path, and is positioned so an arc from it to the entry and exit cam path is generally concentric. As such, tine angularity is less effected in these areas as a result of adjusting the cam track. With this type of timing or pitch adjustment, tine angularity can be changed in the crop gathering portion of the rotational path with minimized effect in the crop entry and exit portions of the rotational path.

The present disclosure relates to a flotation system for swathing rakes, attachable to a baler. It includes a support structure configured to be connected to a baler and to a displacement means; at least one arm including a first end connected to a swathing rake and a second end connected, by means of a hinged articulated joint, to the support structure; the swathing rake; the hinged articulated joint and a flotation cylinder joined to the support structure and to the arm configured such that it acts in traction, absorbing a part of the weight of the arm, and therefore of the swathing rake joined thereto. It also includes support and displacement means and a suspension system for said means.

One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

A calibration system for an agricultural header includes a controller having a memory and a processor. The processor is configured to receive a first position signal indicative of a first position of a reel arm of the agricultural header, receive a first distance signal indicative of a first distance between the reel arm and a terrain feature, receive a second position signal indicative of a second position of the reel arm, receive a second distance signal indicative of a second distance between the reel arm and the terrain feature, determine a calibration curve having a plurality of offset distances of the reel arm based on the first position, the first distance, the second position, and the second distance, and select an offset distance of the plurality of offset distances based on an operational position of the reel arm and the calibration curve.

A non-split bearing design for use with a harvester pick-up reel. In one specific embodiment, the outer member directly engages the inner member. In another embodiment, the bearing is provided as being an interchangeable roller bearing, and in that case there is preferably an intermediate member which is disposed between the outer member and the inner member. Regardless, providing that the bearing is non-split provides that the design is simplified, as well as provides that the inner bore, i.e., the bore which engages the bat tube, can be more easily controlled, thereby reducing or even eliminating service requirements.
