A display system for displaying image data of an environment of a machine includes a display screen and a plurality of imaging devices communicably coupled to the display screen. Each of the plurality of imaging devices generates image data of the environment of the machine and has an associated operating parameter. The plurality of imaging devices stores the image data in an uncompressed form. The plurality of imaging devices compresses the image data and generates signals indicative of the compressed image data. The plurality of imaging devices receives the operating parameter associated with at least one another imaging device. The plurality of imaging devices transmits the compressed image data to the display screen based on the associated operating parameter and the received parameter of the at least one another imaging device. The plurality of imaging devices displays an image on the display screen based on the transmitted image data.

A valve system, including first, second, third and fourth ports, a first flow path connecting the first and second ports, a second flow path connecting the third and fourth ports, with valves connected in the first and second flow paths, and energizable to block the same. A third flow path connects the first and second ports and a fourth flow path connects the third and fourth ports. The third and fourth flow paths are more restricted than the respective first and second flow paths. A fifth flow path connects the first and fourth ports and a sixth flow path connects the second and third ports. When the third and fourth flow paths are open, the first, second, fifth, and sixth flow paths are blocked. When the first and second flow paths are open, the third, fourth, fifth, and sixth flow paths are blocked. When the fifth and sixth flow paths are open, the first, second, third, and fourth, flow paths are blocked.

A work machine includes: a chassis; a backhoe assembly carried by the chassis, the backhoe assembly including: a boom pivotably linked to the chassis at a boom pivot point; a boom angle sensor associated with the boom pivot point; a stick extendably linked to the boom; a stick extension sensor associated with the stick; a bucket pivotably linked to the stick at a bucket pivot point; and a bucket angle sensor associated with the bucket pivot point. A controller coupled to the boom angle sensor, the stick extension sensor, and the bucket angle sensor is configured to: determine a boom angle of the boom; determine a stick extension of the stick; determine a bucket angle of the bucket; and output a bucket location signal corresponding to a current bucket position and a current bucket orientation, relative to the chassis, based on the determined boom angle, stick extension, and bucket angle.

A back guard for a loader bucket is removably mountable to the bucket and can accommodate buckets having different widths. A bucket assembly that includes the bucket and the back guard can accommodate stacked items, such as wood, for transport on the loader bucket. It has a back plate sufficiently strong to hold debris, while not obstructing the vision of the tractor operator. The back plate is slideably disposed relative to left and right supports that are mountable, respectively to the left and right sides of the bucket to provide a sliding mechanism. Each side of the back guard can accept additional implementations, such as left and right side guards useful for further containing the items in the bucket, so that more items can be transported. A method of forming the back guard includes welding components thereof.

A power operated locking device for securing for example a tooth or an adaptor, to a ground engaging system, the lock having an internal motor, and sensing system operated by remote wireless technology to unlock and lock the locking device, and a wireless transmitting handheld device for the locking, and unlocking of the power operated locking device, wherein the motor and drive and electronic response circuits are all contained within the power operated locking device.

A payload management system embodiment may include a force sensing system operatively associated with a bucket of an excavator. The force sensing system senses a magnitude of a force required to hold the bucket at a defined position with respect to a reference datum. An angle sensing system operatively associated with the bucket senses a direction of the force with respect the reference datum. A processing system operatively associated with the force system and the angle sensing system processes data relating to the magnitude of the force and the direction of the force to determine the amount of the payload in the bucket.

A crusher bucket comprising a casing in which there are mounted crushing means comprising a fixed jaw and a movable jaw, in which the movable jaw is supported on the casing by means of a pair of eccentric shafts, wherein at least one of the eccentric shafts is directly fixed to the side walls of the casing.

A tooth adapter defining top and bottom walls and side walls, an adapter recess in one side, a retention means in the adapter recess, a bolt with a fastening inserted in the recess, a collar formed on the bolt of predetermined diameter, a tooth having side walls and defining a hollow chamber fitting over the adaptor, a through tooth bolt opening formed in a tooth side wall of predetermined diameter, the tooth bolt opening being located to register with the adaptor recess, when the tooth is positioned on the adapter. In one version the diameter of the collar is slightly greater than the diameter of the tooth bolt opening, to create a locking effect.

A skid device and a loader bucket assembly includes the skid device, which include a ski-shaped base plate. The skid device is attachable to a front end of a loader bucket including a plurality of mounting holes for securing an accessory, such as an edge plate and a toothbar, to a bottom side of the loader bucket at a front side thereof, with a portion of the accessory extending forwardly of a front edge of the loader bucket when the accessory is mounted to the loader bucket. The skid device is also attachable to the loader bucket without the accessory mounted thereto. Two or more skid devices can be attached to the front end of the loader bucket to enable it to move materials on the ground.
