Abstract: A turning work vehicle comprises a lower travel body, an upper turning body, a work device, a rotation body, and a support column. The lower travel body is provided with a blade. The upper turning body is supported by the lower travel body so as to be able to turn. The work device is supported by the upper turning body so as to be able to rotate. The rotation body is provided to the blade. The support column is provided so as to project from the rotation body. A target prism, which is the measurement object of a total station, can be secured to the support column. The rotation body rotates in relation to the blade, whereby the posture of the support column is configured so as to be able to switch between an upright posture and a fallen posture.

Abstract: A controller includes one or more memories and one or more processors. The one or more processors are configured to receive an input image. The input image contains a first pictorial view that includes a work implement of a work machine. The one or more processors are also configured to generate an output image containing a second pictorial view and an indication element superimposed on the second pictorial view. The second pictorial view is at least in part derived from the first pictorial view and includes the work implement. The indication element includes at least one reference line. An alignment of one or more portions of the work implement with the at least one reference line indicates that the one or more portions of the work implement are positioned at a desired height from a ground surface.

Abstract: Work machines and methods and systems to control and determine a position of an associated implement are disclosed. An example work machine including a first vehicle component movable relative to a second vehicle component; and a processor to: cause the first vehicle component to move toward a commanded position; predict a first position of the first vehicle component of the work machine using first processes; determine a second position of the first vehicle component using second processes; and in response to a difference between the first position and the second position, to cause the first vehicle component to move further toward the commanded position to correct for the difference.

Abstract: Methods and apparatus to track a blade are disclosed. A disclosed example apparatus includes a blade that is pivotable, first and second optical targets operatively coupled to the blade, and a first camera for collecting first imaging data of the first optical target within a first field of view. The example apparatus also includes a second camera for collecting second imaging data of the second optical target within a second field of view. The example apparatus also includes a selector to select at least one of the first or second imaging data, and a processor to determine an orientation of the blade based on the selected imaging data.

Abstract: A control system is disclosed for a machine having a work tool and a traction device. The control system may have an actuator configured to adjust a depth of the work tool relative to a ground surface, a tool sensor configured to generate a first signal indicative of a performance parameter of the work tool, a speed sensor configured to generate a second signal indicative of an actual speed of the traction device, and a controller in communication with the actuator, the tool sensor, and the speed sensor. The controller may be configured to determine that the work tool is engaged with the ground surface and, when the work tool is determined to be engaged with the ground surface, to make a comparison of the actual speed of the traction device with a rotational speed threshold. The controller may then be configured to selectively cause the actuator to adjust the depth of the work tool based on the comparison.

Abstract: A work vehicle may include a chassis, a ground-engaging blade, a sensor assembly, and a controller. The blade may be movably connected to the chassis via a linkage assembly configured to allow the blade to be raised and lowered relative to the chassis. The sensor assembly may be configured to provide a chassis inclination signal indicative of an angle of the chassis relative to the direction of gravity and a blade inclination signal indicative of an angle of the blade relative to one of the chassis and the direction of gravity. The controller may be configured to receive the chassis and blade inclination signals, determine a target grade, determine a distance error based on the signals indicative of a distance between the blade and the target grade, and send a command to move the blade toward the target grade based on the distance error.
