A system for controlling an engagement operation between first and second movable machines includes a separation sensor, a relative speed sensor and a controller. The separation sensor determines a separation distance between the first and second machines. The relative speed sensor determines a relative difference in speed between the first and second machines. The controller determines the separation distance between the first and second machines, decelerates the first movable machine when the separation distance is within a deceleration zone, determines a relative difference in speed between the first and second machines, and generates an engagement speed command to operate the first movable machine at a first ground speed equal to a second ground speed of the second movable machine plus a relative engagement speed when the separation distance is within a buffer zone.

A stopper assembly for a machine. The machine includes an implement. The stopper assembly includes a mount and a stopper. The mount is configured to be coupled to the machine. The stopper is configured to be pivotally coupled to the mount. The stopper is configured to restrict a pivotal movement of the implement when the stopper abuts the machine.

A method for loading a payload carrier of a machine includes receiving, from a camera on the machine, a two-dimensional image of an interior of the payload carrier as material is loaded into the payload carrier. The method further includes filtering the image to identify a contour of the loaded material and determining an area of the contour. The method further includes controlling a display device indicate the determined area.

A ground scraper (10) including: a bowl (12) for holding excavated ground material; a cutting edge (14) mounted at a mouth of the bowl (12) for excavating the ground material; an apron (26) pivotally mounted to the bowl (12) for closing the mouth of the bowl (12); and a hitch assembly (28) including a draft tube (32) and a pair of draft arms (34) extending from the draft tube (32) and pivotally coupled to the bowl (12). Each draft arm (34) including a first portion (36) angled with respect to a second portion (38).
