Abstract: A track tension system including a hydraulic cylinder coupled between a drive frame and idler of a track system, an accumulator and a hydraulic valve that controls flow between the cylinder and accumulator. The cylinder extends and retracts to change the distance between the drive frame and idler which increases and decreases, respectively, tension on the track system. The hydraulic valve can be opened to allow flow between the cylinder and accumulator, and closed to block flow between the cylinder and accumulator. Control factors can be monitored to control valve position. An overload pressure relief can allow flow between the cylinder and accumulator when the hydraulic valve is closed and pressure in the cylinder reaches overload pressure. An orifice can allow constricted flow between the cylinder and accumulator when the hydraulic valve is closed. A check valve can connect the track tension system to a vehicle hydraulic system.

Abstract: Hydraulic power savings for a rear module handler cylinder of a round module cotton harvester is possible by using a regenerative hydraulic arrangement for raising an empty handler and using gravity to lower the handler. A bale handler system for a cotton picker baler includes a handler for receiving a round module that is movable between upright and lowered positions and a handler cylinder operably connected to the handler. The handler cylinder system includes a regenerative valve. The regenerative valve is engaged when the handler moves to the upright position during regenerative handler raise mode of operation, the regenerative valve is not engaged when the handler moves to the lowered position during float handler lower mode of operation. While in the float handler lower mode of operation, the handler cylinder retracts and diverts an oil flow pressure from a base end to a rod end of the handler cylinder.

Abstract: An autonomous off-road vehicle, upon encountering an obstruction while navigating a route, can apply a first machine-learned model to identify the obstruction. In the event that the first machine-learned model cannot identify the obstruction, the autonomous off-road vehicle can apply a second machine-learned model configured to determine whether or not the obstruction can be ignored, for instance based on dimensions of the obstruction. If the obstruction can be ignored, the autonomous off-road vehicle can continue navigating the route. If the obstruction cannot be ignored, the autonomous off-road vehicle can modify the route, can stop, can flag the obstruction to a remote human operator, can modify an interface of a human operator to display a notification or a video feed from the vehicle, and the like.

Abstract: A policy map is obtained that includes a first set of machine settings values for controlling a machine to perform an operation at a site, at different locations in the field. An adjustment component receives sensor signals indicating conditions that will be encountered by the machine in the future, as it moves through the site. A cost determination component determines whether an adjustment is to be made to the first set of settings values, based upon the sensor signals. A predictive vehicle model provides an expected vehicle response, based upon the adjusted settings values that are selected. Control signals are generated based upon adjusted setting values that are generated from the policy map, the expected vehicle response, and the future condition sensor signals. The control signal generator generates the control signals to control a set of controllable subsystems.

Abstract: 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.
