A loader for a work vehicle includes a loader arm, a mast section rotatably connected to the loader arm, an implement removably attached to the loader arm, a first actuator connected between the loader arm and the mast, a second actuator connected between the loader arm and the implement, and a first roller apparatus having a use position and a storage position. The first roller apparatus is positioned nearer a ground surface in the use position than in the storage position. The first roller apparatus is in contact with the ground surface in the use position and spaced apart from the ground surface in the storage position.

Loader with moving apparatus

Method and systems for operating a work vehicle with a selectively interchangeable implement. Image data is captured by a camera (and/or other type of optical sensor) mounted on the work vehicle. The captured image data includes at least a portion of a first implement and the implement type of the first implement is identified by processing the captured image data. Operation information correspond to the identified implement type is accessed from a non-transitory computer-readable memory and an operation of the work vehicle is automatically adjusted based on the accessed operation information for the identified implement type. In some implementations, the implement type is determined by providing the captured image data as input to an artificial neural network and, in some implementations, the artificial neural network is configured to also output an indication of a current operating position of the implement based on the captured image data.

A debris accumulation control system is provided for usage within a work vehicle including an operator station and a work vehicle compartment. In embodiments, the work vehicle debris accumulation control system includes a display device located in the operator station of the work vehicle, a three dimensional (3D) imaging device having a field of view (FOV) encompassing a debris-gathering region of the work vehicle compartment, and a controller operably coupled to the display device and to the 3D imaging device. The controller is configured to: (i) utilize 3D imaging data provided by the 3D imaging device to estimate a debris accumulation risk level within the work vehicle compartment; and (ii) generate a first visual alert on the display device when the debris accumulation risk level surpasses a first predetermined threshold.

Work vehicle debris accumulation control systems

A method of removing debris from a screen cover has a first mode of operation which includes: activating first and second fans to move first and second portions of air through screen cover and into a plenum, and moving the first and second portions of air from the plenum into a heat exchanger. A second mode of operation includes: deactivating the first fan for a first time period, activating the second fan for the first time period to move a third portion of air into the plenum, moving a first part of the third portion of air from the plenum into the heat exchanger during the first time period, and moving a second part of the third portion of air from the plenum through the screen cover during the first time period such that the second part of the third portion of air removes debris from the screen cover.

Method of cleaning an air inlet screen of a work vehicle

Systems and methods are disclosed herein for controlling cooling fans in a self-propelled work vehicle having a main frame supported by wheels or tracks. The cooling fans direct ambient air in accordance with at least one inlet in the main frame, and selectively operate in first and second opposing directions. A perception system is supported by the main frame and configured to provide perception data (e.g., perception data) corresponding to a field of vision which includes the at least one inlet and at least a portion of an associated working area. A controller obtains the perception data and automatically determines characteristics relating to contamination of the cooling system based at least On the perception data. The controller further generates output signals to the cooling fans based on at least one of the determined contaminant characteristics, for example a debris location, type, density, and/or quantity as relating to contamination of the cooling system.

A vehicle, a system, and a method for controlling air movement through the vehicle with a fan of the vehicle is provided. The vehicle includes the fan mounted to the vehicle and configured to move air at a fan end of the vehicle, an object detector mounted at the fan end of the vehicle and configured to detect an object within a detection distance from the fan end of the vehicle, and a controller configured to control actuation of the fan based on detection of the object within the detection distance at the fan end of the vehicle.

Vehicle and system and method of controlling air movement with a fan of a vehicle

A work machine that has a chassis, a payload section, a controller, a payload sensor in communication with the controller, and an orientation sensor that identifies the orientation of the work machine to the controller. The controller determines a center of gravity for the work machine considering a payload weight identified by the payload sensor and sends an alert when the location of the center of gravity and the orientation of the work machine create an unstable condition.

Vehicle stability warning system

A work vehicle includes an engine, a compressor used to compress an air toward the engine, a charge air cooler, a sensor, and a control unit. The charge air cooler comprising or coupled to a fan. The fan can rotate in a first direction to remove a heat of the air and to rotate in a second direction reverse to the first direction so as to blow a debris. The control unit is electrically coupled to the engine and to the fan. The control unit predicts whether a temperature of the air exceeds a threshold based on a signal received from the sensor. When the temperature of the air is below the threshold, the fan can rotate in the second direction. When the temperature of the air is equal to or above the threshold, the fan is inhibited from rotating in the second direction.
