An example work machine control system includes target fill level determination logic configured to determine a target fill level for a container of an earth-moving work machine, fill level measurement logic configured to receive a sensor signal from a sensor that detects contents of the container and generate a measurement metric indicative of a current fill level of the container based on the sensor signal, and control logic configured to generate a machine control signal based on the measurement metric and the target fill level.

A control method to operate a scraper over ground, the control method comprising: receiving a signal indicative of a desired attack angle between a cutting edge of the scraper and the ground; receiving a height control signal to control a cutting edge height; receiving one or more measuring signals from one or more sensors, calculating a measured attack angle based on the one or more measuring signals; comparing the measured attack angle and the desired attack angle; and outputting at least one control signal commanding movement of a bowl of the scraper based on the height control signal and a result of the comparing the measured attack angle and the desired attack angle.

A hybrid power train system for a tractor scraper is provided. The hybrid power train system may include a primary power source coupled to a first set of traction devices, a generator coupled to the primary power source, a first electric motor coupled to a second set of traction devices, an inverter circuit coupled to the generator and the first electric motor, an energy storage device coupled to the inverter circuit, and a controller operatively coupled to the inverter circuit. The controller may be configured to engage a first operation mode enabling electrical energy, supplied by the generator and the first electric motor, to be stored in the energy storage device, and engage a second operation mode enabling electrical energy, stored in the energy storage device, to be supplied to the first electric motor to drive the second set of traction devices.

An earth moving implement incorporating left and right rails; a bucket between the left and right rails; left and right pivot axles interconnecting the bucket and the left and right rails for rotating the bucket between earth scooping and blading position; left and right arms extending leftwardly and rightwardly from the bucket's left and right ends, the arms' proximal ends underlying the left and right rails; left and right linear motion actuators respectively positioned leftwardly and rightwardly from the left and right rails, the actuators having bucket ends pivotally attached to the left and right arms; left and right columns rigidly positioned at the rails' rearward ends, the actuators' base ends being pivotally attached to the left and right columns for rotating the bucket; a plurality of wheels rollably mounted to the rails' rearward ends; and a towing tongue rigidly extending from the rails' forward ends.

A box scraper assembly includes a box scraper that is attachable to a tractor for scraping dirt. A plurality of teeth is each movably disposed in the box scraper to dig into the dirt when the box scraper is drawn along the ground. Each of teeth is adjustable between minimum height and a maximum height. An adjustment unit is movably integrated into the box scraper and the adjustment unit is in mechanical communication with each of the teeth. The adjustment unit adjusts each of the teeth between the minimum height and the maximum height. Furthermore, the adjustment unit is in communication with a control on the tractor for actuating the adjustment unit to adjust the teeth between the minimum height and the maximum height.

An example work machine control system includes target fill level determination logic configured to determine a target fill level for a container of an earth-moving work machine, fill level measurement logic configured to receive a sensor signal from a sensor that detects contents of the container and generate a measurement metric indicative of a current fill level of the container based on the sensor signal, and control logic configured to generate a machine control signal based on the measurement metric and the target fill level.

A stall plow removably attaches to a prior art skid steer using available quick connect couplers. The stall plow has a moldboard that is configured to completely remove waste bedding from a livestock free stall from the area adjacent to the curb and deliver it to the alley, where a prior art machine can then complete removal of the waste bedding from the alley. The moldboard includes a primary scraper section and side cutter that scrapes and lifts waste bedding up and over the curb. A curb section and curb flange then shift the bedding over to the alley and drop waste bedding into the alley, where a discharge spreader levels and distributes the waste. An extensible arm and hydraulic extension cylinder adjusts the moldboard transversely relative to direction of travel. An angle and pitch adjuster sets the moldboard for a particular free stall geometry and bedding material composition.

Described is an earth scraper including multiple buckets to receive earth scraped by a scraper blade. A lifter mechanism is provided to move one of the buckets between elevated and lowered positions.

An implement has a frame. First and second shafts are mounted to the frame and rotate along coaxial longitudinal center axes. A tilt actuator is operatively connected between the first and second shafts such that as the tilt cylinder moves from an expanded to a contracted position, it rotates the first shaft in a first direction and the second shaft in an second opposite direction; and from a contracted to an expanded position, it rotates the first shaft in the second direction and the second shaft in the first direction, thereby changing the tilt of the implement. A height actuator is operatively connected between the frame and the tilt actuator and drives the first and second shafts in the same direction to change the height of the implement.

A control method to operate a scraper over ground, the control method comprising: receiving a signal indicative of a desired attack angle between a cutting edge of the scraper and the ground; receiving a height control signal to control a cutting edge height; receiving one or more measuring signals from one or more sensors, calculating a measured attack angle based on the one or more measuring signals; comparing the measured attack angle and the desired attack angle; and outputting at least one control signal commanding movement of a bowl of the scraper based on the height control signal and a result of the comparing the measured attack angle and the desired attack angle.
