A drainage tile stringer system which includes a spool which has an automated hat, which translates along the stinger or shaft of the spool so that the vertical size of the spool is adjustable to accommodate differences in coils of drainage tiles. The system is automated so that a single controller can be utilized to perform all of the hydraulic functions required to load a coil onto the drainage tile stringer system and to adjust the vertical spool dimension.

A joint orientation system is provided for a work vehicle having a chassis and an implement coupled to the chassis at a joint. The joint orientation system includes a first IMU positioned on a first side of the work vehicle relative to the joint and configured to collect a first IMU acceleration and a first IMU angular velocity and a second IMU positioned on a second side relative to the joint and configured to collect a second acceleration and a second angular velocity of the implement. A controller is configured to receive the first and second IMU accelerations and the first and second IMU angular velocities; determine a joint orientation correction based on IMU accelerations and IMU angular velocities; modify an estimate of joint orientation with the joint orientation correction to generate a current joint orientation; and output the current joint orientation for actuation of the implement.

There is disclosed an excavation apparatus (5), such as an underwater excavation apparatus, having means for producing, in use, at least one vortex, spiral or turbulent flow in a laminar flow of fluid, e.g. water. The excavation apparatus (5) comprises a rotor (10) having a rotor rotation axis (A), wherein, in use, flow of fluid past or across the rotor (10) is at a first angle (?) from the axis of rotation (A). The excavation apparatus (5) comprises the rotor (5) and means or an arrangement for dampening reactive torque on the apparatus (5) caused by rotation of the rotor (10), in use. The turbulent flow is provided within, such as within a (transverse) cross-section, of the laminar flow.

A shovel includes an attachment including a working assembly, a diesel engine provided with a supercharger, an oil hydraulic pump connected to the diesel engine provided with the supercharger, and a controller that executes a preload boost function, wherein the preload boost function is for increasing boost pressure of the supercharger prior to increasing a hydraulic pressure load on the oil hydraulic pump, wherein a range accessible by a predetermined part of the attachment includes a partial range at which, upon the working assembly being operated, the preload boost function is to be executed and a partial range at which, upon the working assembly being operated, the preload boost function is not to be executed.

Systems, methods, and apparatuses can accurately determine proper payload transfer from a working implement of a working machine. Such systems, methods, and apparatuses can identify occurrence of a payload discharge event for the working implement; determine whether a position of the working implement at a time of the identification of the occurrence of the payload discharge event is in a preset working area or a preset discharge area; omit the payload discharge event from registration for a tally of discharge material payload amount under a first case where the position of the working implement is determined to be in the working area; and register the payload discharge event for the tally under a second case where the position of the work implement is determined to be in the discharge area. The tally of the discharge material payload amount may be increased by a load amount associated with the load discharge event.

A method for providing a machine operator with an augmented reality view of an environment includes determining a location and orientation of a vehicle. An eye position and gaze of an operator of the vehicle are also determined. Job information to be displayed to the operator of the vehicle is determined based on the location of the vehicle and the orientation of the vehicle. The job information is displayed to the operator based on the eye position and gaze of the operator of the vehicle. In one embodiment, environmental features that can be seen through the windscreen are determined. The job information displayed to the operator is modified based on the environmental features.
